Finally got around to making a video replacing the bad triac on the control board. Much cheaper fix than replacing the board! - th-cam.com/video/T5OyIWVZFKA/w-d-xo.html
If you put in an LED bulb, it will stay on all the time because LEDs require such a tiny amount of current. Whirlpools dimmer switch design will always let a tiny current through even when it says off. Put the original style incandescent bulb in it and it will likely then shut off. This was my problem.
Thank you for your video. It was very helpful. Have a Whirlpool model WMH31017HZ-0, 10/17. Changed the above range bulb WITHOUT unplugging it. Heard a large pop. Fried the light socket and that part of the control panel. Had to replace the light socket and the electric control panel. Repair vs replacement costs were close. Customer service at Whirlpool was not helpful. This video was what was helpful! Thank you. Side note: If you replace the electric control board, the black mechanism that the green ribbon goes in is “tricky”. The black piece does elevate about an eighth of an inch when you pull those tiny black tabs up. When you carefully put the ribbon into the slot, you have to push down gently on the black mechanism to lock the ribbon connection.
Thanks for this video. I was able to follow it exactly and perform the replacement without major difficulty. I was surprised at the trickiness of getting off some of the connectors, especially the two individual wires (black and red). And just in case someone else didn't take enough pics while disassembling--the black wire goes toward the back.
The Triac P/N BT136-600D on my control board P/N W10800189 was shorted between terminals T1 and T2. There are two triacs on the board. The culprit is 7919 (marked on board). Amazon sells them cheap. Replaced it and all is well. Saved some money. 😁
Thanks for the video. Experiencing the same issue. I pressed the Light button and heard a pop and bright flash. I thought the bulb blew, which it did, but apparently it also zapped the control board. Mine is from 2016 (WMH31017FB - 0) and Whirlpool chat was not helpful once they got my S/N and saw that it was well out of warranty. They won't do much of anything beyond confirming for me that there were no recalls on this model. Before seeing this video, I just bought an LED bulb off of Amazon. It's a 5W LED (40W equivalent) and used about $.52 of electricity per year if left on 24/7, so decided to go that route and will likely stay that way unless I decide to buy the triac. Thanks for the video.
I had the same issue from a shorted board that was the result of changing a burned out light bulb. After researching the cost of the replacement board, I decided it was a better long term solution to just buy a new microwave. No more Whirlpool microwave ovens for my house.
Ya pretty sad. Ours is 2 years old, figured it was just a burnt out bulb. Nope needs this to be replaced. For $120 I might be going with a better made product. I’ll never own another whirlpool appliance again.
I discovered the failed triac a couple weeks ago after locating the schematic online. I ordered the part and soldered it in replacing the tested bad part. This took slightly longer time and required a little more skill than board swapping. The money saved was substantial compared to the board-swapping option. David Shaddock beat me to posting; and wrote a thorough posting at that. I am sure others can make this same fix, or at least try because it is cheap to do.
You can usually find the schematic tucked away inside the microwave- mine was under the top bezel thing in a black plastic envelope...I posted a vid on this
I have this exact model at work. Apartment maintenance tech here. Instead of replacing the whole control board, if you have a soldering kit, you can replace the transistor for the bulb. They usually run around $0.75 a piece and take no longer than 30-45 to do.
TY TY! I have a GE microwave with the same problem and in an apartment. I was worried about leaving the light on until maintenance could get here, the light was getting quite hot, and I couldn't figure out where the plug is. Mine is in the same place as in the video. So, while not fixed, at least I don't have to worry about waking up in the middle of the night to a fire in my apartment. Thank you!
Thank-you for posting this fix. I have a $375 Maytag that has the same design and issue. Same bulb issue after only 5 months. Notice that Amazon doesn’t sell Maytag and Whirlpool microwaves. Amazon would go broke on return shipping. How many people buying these things are able to lift this off the wall replace a microchip board and lift it back on to mount it. Its going to cost the price of the machine to have it repaired.
There is an easy way to take it off the wall and put it back on again. When I installed my Whirlpool I constructed a wood platform to sit on the cook top, 2 " lower than the microwave sits installed. Releasing the front mounting bolts dropped it at a slight angle, enough to lift the back out of the wall bracket clips with it resting square on the platform. I am a 73 year old DIY'er lacking the strength I had when younger, though I am still strong enough to lift it from the lower counter top of the island to the platform or the reverse. It was easy as pie :)
Will it be dangerous to just leave the light on all the time. Everything else works fine, do not want to spend a lot of money just for a light. I can tell it is on "high". The bulb gets a little hot
That was a great video explanation for my problem! Moved into a home the end of last month that has an otr microwave with this exact issue. The bulb was burnt out and been trying bulb after bulb, all staying on as soon as they're screwed in and the power is plugged back in. Nice to know there's a solution, but I'll have to weigh the decision of spending that much to replace a part or just buying a new one, because it is a bit older and who knows what kind of maintenance the previous owners of the home actually did.
You were totally right on about the fix. The control board I purchased had a update to the thermistor . The added an integrated thermistor. Hopefully this will last longer than 3 years.
After going through 10 different bulbs that would not turn off I replaced socket 1st and will do this now. Thank you for this video and I hope it works for mine. Very very similar model microwave
This is a great video that covers the easiest way to fix. The board cost around 100 bucks tho...the component on the board that controls light dimming is called a Triac, and if you can find the schematics and are handy with a solder gun, you can replace just that part for much cheaper. Not everyone can solder tho, so this is best for most folks
@Apartment Maintenance Pro...Thank you for taking the time to post your work around. This is the exact issue I'm having with our Whirlpool microwave! This unit was replaced 2.5 years ago. This morning, I replaced the burnt out bulb with the same: a 40 watt Feit Electric 40-Watt EQ 2.2-in T7 Soft White Dimmable Appliance Light Bulb. The bulb works and that tells me the light socket and wiring works. just can't dim or shut-off the bulb with the control panel on the right side of the unit. Maybe it's the control panel. I'm subscribing to your channel. Helpful.
Hi Carl i had same problem. I fixed my two year old whirlpool by soldering in a new triac on the board. cost $10 for a 12 pack on amazon. Just match the part # on the triac.
Question: The bulb burnt out on my Whirlpool microwave. When I went to change the bulb, the bulb broke off of the base and got stuck in the socket. I unplugged the power and used pliers to unscrew the base that was stuck. It was a challenge because as you know, the socket faces towards the wall, and it's nearly impossible to see directly inside of it without pulling several muscles in your neck and back, or pulling the whole stove away from the wall to be able to stand right underneath it. So after struggling, I finally got it loose and unscrewed it, screwed in the new bulb, and plugged it back in. The button on the microwave that controlled the light worked perfectly fine before the bulb burnt out and I fiddled with it. So my question is...before I go replacing control panels or anything like that...is there something I might've done while I was trying to get the base of the bulb un-stuck? Like maybe loosened a connection of some sort? The microwave is only a year old, and that was the first time it needed the bulb changed since it was installed. Sorry for the novel about my bulb battle. Any advice would help! Thanks!
The bulbs in these microwave take out circuits like crazy if changed when power is applied to them. Check out the pinned comment, if you are good a circuitry this can be fixed for a few bucks.
Same exact thing just happened to me. Came to change the bulb and it exploded on me. Put a new one in and it won’t shut off. The original bulb only lasted 4 months and it doesn’t even get turned on all that much.
Holy. Crap. This is so weird because the same exact scenario to the T just happened to me. Light bulb broke off and everything lol. Wild. Anyone able to have this covered under warranty?
Whirlpool should make such flimflam cheap motherboards. Mine went out only after a year in service, and it wasn’t covered by their warranty..😖 Nice video 👍
🆘 Think twice before you buy the Whirlpool microwave in the above video. When the light won’t shut off the only way to fix it is to buy a new motherboard, and they range in price from $155 to over $350 plus tax and shipping. And it’s an inherent problem in this Whirlpool microwave unit 0:05 wmh53521hz. The guy in the video does an excellent job showing how to replace it but you can buy a new microwave for $450 or LED stick up under cabinet lights for under $10 as a solution.
I have the same problem but my model is different. WMH31017FS0, How do i figure out what part number I need for the control board? Thank you in advance.
What is the part number on the Triac? My model is Whirlpool WMH31017HZ, bulb burned out changed it and it now want go dim or go out. Part # exactly, on triac pls, and was reading all the comments and it appears as the bulb goes bad replacing it seems to cause the problem. Perhaps if it happens again for me I will unplug the oven then replace the bulb. Perhaps that will work, if not a few more slang words @ whirlpool. Thanks for the video AMP, and all other comments (bunches) on here.
Take off the top cover / vent on the front side and grab the tech sheet. This should tell you what triac you need. Keep in mind there's a new model updated almost every year, so going off the tech sheet is the best bet if you can't get the info from Whirlpool
Question, this just happened in the apartment I'm renting. I leave the light on all the time anyways. Is there any harm in just leaving it not turning off?
I have the same microwave it's about a year old. On the inside of the door it's has July 2020. Before the light under the microwave blew out I noticed a few times when I would close the microwave door ( not slamming it) the light would turn on. I would select the button to turn it off. That happened a few times and eventually the bulb went out. I've replaced the bulb... but I killed the power first from the breaker because the internet made me afraid and I thought I was going to get shocked...anyway....I replaced the bulb and now the light won't turn off. I obviously had issues before the bulb went out..and I didn't address it right then as I should have....Has this ever happened to anyone else? Thanks. And BTW great video!
These microwaves are weird with the under light. I've had the same issue after swapping out a new board a few months later. I gave up honestly a 30 dollar under light you can stick on the cabinet from Amazon is where it's at.
@@ApartmentMaintenanceProa whole deferent brand of microwave is the answer. Second Whirlpool I've had in a row that has done this and it's crap on their part. I know one thing for sure, it'll be the last Whirl poo in this house.💩
The question no one has asked: CAN I LEAVE THE LED ON HIGH ALL THE TIME WITHOUT DAMAGING THE CIRCUIT BOARD? Yes, I know that the replacement LED bulb is not dimmable. But it doesn't use much electricity, and makes a great night light.
Great explanation! I can’t believe how unreliable these modern microwaves are. I can’t get my light to turn on. I replaced the bulb, and the bulb socket. Light still won’t come on. Microwave is 8 months old… Maytag.
We just received a brand new KitchenAid microwave. The original bulb gets very hot so replaced with an LED light bulb and having this same issue. At least the bottom of the microwave won't burn us now.
how can you fix one that won't turn on at all, even tho I replaced the build.. its a GE over the range microwave and the microwave works fine but the light over the stove won't come on. how can I fix that?
I have same problem with 3-year-old Whirlpool microwave. Have no interest in replacing board with one that is likely to crap out in a couple of years. The bulb goes, and I will stick on a short LED strip I have laying around; it will probably last longer than I do. So, when is Whirlpool going to fess up, do a recall, and fix it so you don't need a $200 board every 2-3 years, or less? Anybody calling them out, on this?
I have exactly the same problem and I am pretty sure it is the control board. Would you point me out to a source where to buy a new board? My microwave is a Whirpool, very similar to yours, if not the same. And thanks for the video!!
Hi my power went down at my house and now the microwave light timer is very low on brightness... It's a whirlpool model wmh32519hz -4 I don't k ow how to increase the led brightness
I just replaced my oem bulb with an LED bulb... oem halogen bulb works as it should, led bulb shows exactly the results you showed here very dim but still on when set to off. I looked at the replacement LED bulb... "not to be used with dimmers" in very small letters but nowhere mentioned on the packaging The only way to turn it off was unscrew it and screw it back in and then it was off.
David Shaddock 2 weeks ago I found a cheaper fix for my Whirlpool WMH53521HZ-3 over range microwave that the bulb blew out and would not run off after replacing the 40W bulb (8206232A). The cause was on the control board. The Triac (BT136-600D, labeled 7919) had shorted. I unplugged the microwave, removed the control board and checked the resistance between MT1 (pin 1, nearest the white 6 pin connector ) and MT2 (pin 2, middle) there is a low resistance and it should be open with no power to the board. I purchased another Triac from DigiKey (Digikey 1740-1018-ND, $0.63 each), removed the old triac, and soldered the new one in. After installing the repaired control board, replacing the bulb, plugging in the microwave, the light can be turned off and controlled again. This is a lot cheaper than buying a new control board.
Why not use a relay instead of a Triac, to save a few cents? Then this problem could be avoided, and an LED would work. They ship new micros with 25-watt bulbs instead of 40 watts to save a few cents.
@@chrissimon8368 Thanks for the tip! Put the new Triac in and the light works as it should. My microwave is a Maytag but the item was the same. Saved me the $250 Maytag wanted for the control board (plus a 4 - 6 week delivery). Such an easy and inexpensive fix!
I will never again buy a Whirlpool product. I have the same issue with my microwave, It is a manufacturing defect. Whirlpool used to make quality appliances, but those days are long gone. Whirlpool now makes junk.
I just changed the surface lightbulb on our 2020 model and used a 40w LED replacement. It cycles fine from full to half light but now the light won't go off. It worked fine with the old bulb and I can't believe changing the bulb affected the board. Odd though. I don't think I'll spend the $ on a new board, it's very dim when it should be off.
@@ApartmentMaintenancePro Same thing here. The replacement (I got an LED without thinjking about it) will NOT go fully off. Is this an issue, or does it matter? It's very dim, but still on. I assume it won't get so hot it will burn the house down?! Please advise if otherwise...lol
I just either unscrew the LED bulb and screw it again or just unplug and plug micro and it turns it off, I don't use it much so either step doesn't bother me... Update: as someone else suggested I placed a normal bulb and problem solved! Yey!
If the light stays on, then a relay may be stuck in the on position providing constant power to the bulb socket. Removing the bottom panel provides access to the bulb socket. Adding a switch to the positive line to the socket and installing the switch on the side of the case, would allow you to turn the light on and off.
OK, you asked for a cheaper way to fix the light problem. Here goes: I bought a single pole, single throw toggle switch and installed it on the bottom cover and wired it into one of the leads going to the light socket. Took about half hour and it is fixed. There is only one setting (full) but it beats paying a couple hundred bucks for a new board when you can buy a new microwave for a little more than that.
I had the same problem where the new LED light I put in would not turn off so I took it out replace it with a conventional light and it worked properly.
Just replaced the underside bulb on my Whirlpool microwave, and this same thing happened. I know I fried the circuit board because it smelled like something burning. I quickly unplugged it. Didn't even think to unplug it before putting in the new bulb.
The Part# w10892389 - Search that, looks like amazon is sold out. The main site I use is partsselect if Wilmar is sold out of them. Whirlpool also sells them directly on their site. Keep in mind that they are expensive, so a more risky, but cheaper option would be to search eBay, or Facebook Marketplace. I know some techs that sell old used parts but if they have good feedback then it may be worth the risk and save you a bunch of money. Hope that helps.
yeap, better off either installing a switch on the power side of the bulb socket, or just going without the light until the unit totally fails. This is a horrible defect.
Customers need to think twice before buying the Whirlpool microwave- wmh53521hz-5. When the light won’t shut off the only way to fix it is to buy a new motherboard, and they range in price from $156 to over $300 online plus tax and shipping. Also $150 for service call to install it. And it’s an inherent problem in this Whirlpool model. You can buy a new microwave for $450 or pay that much for repairs or buy an LED stick up under cabinet lights for $12 to $18 as a alternative solution.
The original bulb was fine until I changed to LED. Now the light stays on when set to off. Is there a fix for that, or will all LED bulbs stay on? I have a 2016 version of your microwave.
Yeah this happened to to me too. I suppose you could put some kind of resistor in the line. But I just left it as is. Have a night light now. And it doesn't really use any power.
Ya still haven't figured out a way around it, it sucks. Someone in the comment mentioned wiring in a relay/switch under the microwave might be the cheapest/best alternative
Whirlpool sucks... have one just like yours and not too happy with it. Had a recall on it for fire hazard, and I was already having issues with the first one to start with. A few months or so after receiving a new one, the door sensor was acting up where it wouldn't send a signal saying that the door is closed, so I had to do some internet searching and luckily I found a video on You tube. And now, I'm here again trying to figure out how to get the light to turn off after replacing the bulb. It's like the company pushed the product out w/out thoroughly testing it.
@@ApartmentMaintenancePro I might go for a Bosch since one of my family members has a dishwasher and stove and have been using it for five years or more with no issues. They just bought the over the range microwave and we'll see how it holds up over time.
Just bought a Whirlpool 1.9 cf the light was not bright enough for me I switche out to an Led & the bulb would not turn off . Switched back & works fine. Sept 2023. Angry now to dim for me.
Why not use a relay instead of a Triac, to save a few cents? Then this problem could be avoided, and an LED would work. They ship new micros with 25-watt bulbs instead of 40 watts to save a few cents.
Control panels are “cheap plastic”? Well the manufacturer has got to continue making its money through parts exchange/replacement from the customer. I guarantee you that I will break off more than one of those clips when I take mine apart to change that motherboard if I can’t get my bottom light to turn on.
That's too $$$ - I'm just going to leave the cover off with a LED bulb (a regular bulb was super hot)and turn it to the right when I need light and turn it to the left when I don't.
Same problem with my whirlpool WMH53520CS-5 bought in 2016. Looks just like your microwave. Man I hope I don’t have to change the whole control panel. 👎🏻 Booooooo
This is a shit microwave from Whirlpool. Two light replacements, first not unplugged, second was and two board failures. First was covered by the warranty, not the second. Shoddy product from Whirlpool
Omg my bulb went out and then I replaced it - since then the bulb won’t turn off. So i had to remove the bulb. Thank God I seen this video to determine its the circuit board! wish me luck!
Finally got around to making a video replacing the bad triac on the control board. Much cheaper fix than replacing the board! - th-cam.com/video/T5OyIWVZFKA/w-d-xo.html
Did as you said and it works fine with the new Triac, Thanks bunches!

We don't use the LED bulbs in ours but good call if it helps others with this issue 👍

The bulbs in these microwave take out circuits like crazy if changed when power is applied to them. Check out the pinned comment, if you are good a circuitry this can be fixed for a few bucks.
Same exact thing just happened to me. Came to change the bulb and it exploded on me. Put a new one in and it won’t shut off. The original bulb only lasted 4 months and it doesn’t even get turned on all that much.
Also my problem! Maybe this should be whirlpools problem.
Holy. Crap. This is so weird because the same exact scenario to the T just happened to me. Light bulb broke off and everything lol. Wild. Anyone able to have this covered under warranty?
Have the same issue. My understanding is when the bulb burns out especially if it breaks from the housing it must short out this Triac
I appreciate your time to show how remove the microwave parts plus change the light issue thanks buddy
Thanks for watching Lu
Will it hurt to leave the light burning all the time? Is there risk of a fire in control board area? This seems to be a design defect by Whirlpool.
Do you need the P4 the one on Amazon doesn’t have one
Take a picture of the plug connections on the panel before disconnecting. Once the plugs are reconnected, test the functions before final assembly.
Thanks for the tip 👍
Whirlpool should make such flimflam cheap motherboards. Mine went out only after a year in service, and it wasn’t covered by their warranty..😖 Nice video 👍
🆘 Think twice before you buy the Whirlpool microwave in the above video. When the light won’t shut off the only way to fix it is to buy a new motherboard, and they range in price from $155 to over $350 plus tax and shipping. And it’s an inherent problem in this Whirlpool microwave unit 0:05 wmh53521hz. The guy in the video does an excellent job showing how to replace it but you can buy a new microwave for $450 or LED stick up under cabinet lights for under $10 as a solution.
Is this for all whirlpool microwaves or would I need to find the exact model number and information on my exact one?
I always use the exact model as parts tend to change on updated models
I have the same problem but my model is different. WMH31017FS0, How do i figure out what part number I need for the control board? Thank you in advance.
What is the part number on the Triac? My model is Whirlpool WMH31017HZ, bulb burned out changed it and it now want go dim or go out. Part # exactly, on triac pls, and was reading all the comments and it appears as the bulb goes bad replacing it seems to cause the problem. Perhaps if it happens again for me I will unplug the oven then replace the bulb. Perhaps that will work, if not a few more slang words @ whirlpool. Thanks for the video AMP, and all other comments (bunches) on here.
Take off the top cover / vent on the front side and grab the tech sheet. This should tell you what triac you need. Keep in mind there's a new model updated almost every year, so going off the tech sheet is the best bet if you can't get the info from Whirlpool
Question, this just happened in the apartment I'm renting. I leave the light on all the time anyways. Is there any harm in just leaving it not turning off?
Nope
Bulb will burn out after about 30 days. Will keep buying bulbs.
@@StevesSpot the bulb is rated for 20,000 hours when fully on. Pretty sure it will take more than 30 days to burn out.
The incandescent bulbs run very hot. Considering switching to led and let that stay on.
How much is the board? The microwave is only 130?
Took socket out. Line is constantly powered...so something wrong with switch or short/arc? Somewhere.
Thank you! Now I can sleep in my hotel in complete darkness, just how I like it!
Where you get the board?
Where is the link for the board
I have the same microwave it's about a year old. On the inside of the door it's has July 2020. Before the light under the microwave blew out I noticed a few times when I would close the microwave door ( not slamming it) the light would turn on. I would select the button to turn it off. That happened a few times and eventually the bulb went out. I've replaced the bulb... but I killed the power first from the breaker because the internet made me afraid and I thought I was going to get shocked...anyway....I replaced the bulb and now the light won't turn off. I obviously had issues before the bulb went out..and I didn't address it right then as I should have....Has this ever happened to anyone else? Thanks. And BTW great video!
These microwaves are weird with the under light. I've had the same issue after swapping out a new board a few months later. I gave up honestly a 30 dollar under light you can stick on the cabinet from Amazon is where it's at.
@@ApartmentMaintenanceProa whole deferent brand of microwave is the answer. Second Whirlpool I've had in a row that has done this and it's crap on their part. I know one thing for sure, it'll be the last Whirl poo in this house.💩
My microwave’s tray doesn’t stop turning and even with door open it sounds like it’s running and the round tray keep turning ???? Any advice ?
The question no one has asked: CAN I LEAVE THE LED ON HIGH ALL THE TIME WITHOUT DAMAGING THE CIRCUIT BOARD? Yes, I know that the replacement LED bulb is not dimmable. But it doesn't use much electricity, and makes a great night light.
These circuit boards are weak sauce so do so at you own risk :)
Great explanation! I can’t believe how unreliable these modern microwaves are.
I can’t get my light to turn on. I replaced the bulb, and the bulb socket. Light still won’t come on. Microwave is 8 months old… Maytag.
Might be a bad relay on the board I would trace it out . Will need to be handy with a multimeter
Has anyone mentioned how dangerous it can be if the capacitor is not discharged?
It can be dangerous yes. The capacitor is behind a metal frame though that has warning tags all over it
Muchas gracias 😊 en mi trabajo tengo mucho ese problema y asta hoy me doy cuenta como repáralo🙏🏻
Thank you 🙏🏻🙏🏻
I’m sorry what’s wrong with a nightlight?
How much does a control board cost? Is it a very expensive part.
We just received a brand new KitchenAid microwave. The original bulb gets very hot so replaced with an LED light bulb and having this same issue. At least the bottom of the microwave won't burn us now.
how can you fix one that won't turn on at all, even tho I replaced the build.. its a GE over the range microwave and the microwave works fine but the light over the stove won't come on. how can I fix that?
Make sure the bulb is good. Electrical troubleshooting with a meter will probably be necessary if that’s not the case
I have same problem with 3-year-old Whirlpool microwave. Have no interest in replacing board with one that is likely to crap out in a couple of years. The bulb goes, and I will stick on a short LED strip I have laying around; it will probably last longer than I do. So, when is Whirlpool going to fess up, do a recall, and fix it so you don't need a $200 board every 2-3 years, or less? Anybody calling them out, on this?
Led strip is a good idea and much cheaper than a board
I have exactly the same problem and I am pretty sure it is the control board. Would you point me out to a source where to buy a new board? My microwave is a Whirpool, very similar to yours, if not the same. And thanks for the video!!
Hi my power went down at my house and now the microwave light timer is very low on brightness... It's a whirlpool model wmh32519hz -4 I don't k ow how to increase the led brightness
I would try replacing the bulb 👍
@@ApartmentMaintenancePro its working again.. I did nothing.
Dude ,that was so easy ,your explanation was right on the money thanks for sharing 👍😉
No problem 👍 Glad it helped
same problem but the model number is different 2018 but everything looks the same as what you have
How much did the control board cost?
might be few fingers hahah
Haha..bro you got a like just for the sound effects. 🤣
Sweet! Glad someone other than me likes them 😂
I just replaced my oem bulb with an LED bulb... oem halogen bulb works as it should, led bulb shows exactly the results you showed here very dim but still on when set to off.
I looked at the replacement LED bulb... "not to be used with dimmers" in very small letters but nowhere mentioned on the packaging
The only way to turn it off was unscrew it and screw it back in and then it was off.
Yep, that's exactly what I do
So how much did it cost?
I was hoping I wouldn’t have to change the whole board. Damn, I saw your comment you’re in Denver. So am I
Ya I havent figured out a way around it without adding extra wiring and a switch. Gonna be a cold one in Denver this weekend !

I found a cheaper fix for my Whirlpool WMH53521HZ-3 over range microwave that the bulb blew out and would not run off after replacing the 40W bulb (8206232A). The cause was on the control board. The Triac (BT136-600D, labeled 7919) had shorted. I unplugged the microwave, removed the control board and checked the resistance between MT1 (pin 1, nearest the white 6 pin connector ) and MT2 (pin 2, middle) there is a low resistance and it should be open with no power to the board. I purchased another Triac from DigiKey (Digikey 1740-1018-ND, $0.63 each), removed the old triac, and soldered the new one in. After installing the repaired control board, replacing the bulb, plugging in the microwave, the light can be turned off and controlled again. This is a lot cheaper than buying a new control board.
Why not use a relay instead of a Triac, to save a few cents? Then this problem could be avoided, and an LED would work. They ship new micros with 25-watt bulbs instead of 40 watts to save a few cents.
@@chrissimon8368 Thanks for the tip! Put the new Triac in and the light works as it should. My microwave is a Maytag but the item was the same. Saved me the $250 Maytag wanted for the control board (plus a 4 - 6 week delivery). Such an easy and inexpensive fix!
I will never again buy a Whirlpool product. I have the same issue with my microwave, It is a manufacturing defect. Whirlpool used to make quality appliances, but those days are long gone. Whirlpool now makes junk.
I just changed the surface lightbulb on our 2020 model and used a 40w LED replacement. It cycles fine from full to half light but now the light won't go off. It worked fine with the old bulb and I can't believe changing the bulb affected the board. Odd though. I don't think I'll spend the $ on a new board, it's very dim when it should be off.
Right on, thanks for sharing with us 👍
Yes I think I will just let light on save 300 plus as well
I had the same problem but I switched back to a conventional bulb and it stopped so just try switching back to a normal bulb.
@@ApartmentMaintenancePro Same thing here. The replacement (I got an LED without thinjking about it) will NOT go fully off. Is this an issue, or does it matter? It's very dim, but still on. I assume it won't get so hot it will burn the house down?! Please advise if otherwise...lol
I just either unscrew the LED bulb and screw it again or just unplug and plug micro and it turns it off, I don't use it much so either step doesn't bother me...
Update: as someone else suggested I placed a normal bulb and problem solved! Yey!
I replaced the control board and the bulb still won't turn off. It will go on and do high and low, but still won't turn off. Any other ideas?
If the light stays on, then a relay may be stuck in the on position providing constant power to the bulb socket. Removing the bottom panel provides access to the bulb socket. Adding a switch to the positive line to the socket and installing the switch on the side of the case, would allow you to turn the light on and off.
wouldn't a switch on either cable do the job?
@@zaratron dude!! You never put a switch on the return line. Always on the supply line.
no he means if there is 2 bulbs@@dummgelauft
OK, you asked for a cheaper way to fix the light problem. Here goes: I bought a single pole, single throw toggle switch and installed it on the bottom cover and wired it into one of the leads going to the light socket. Took about half hour and it is fixed. There is only one setting (full) but it beats paying a couple hundred bucks for a new board when you can buy a new microwave for a little more than that.
Thanks spitlist!!
It’s actually a bad solder on the board. Very common
can we fix the board instead of replace it ?
I had the same problem where the new LED light I put in would not turn off so I took it out replace it with a conventional light and it worked properly.
From what I gathered from reading about the dimming technology, it appears not to be compatible with LED dimming technology.
Mines a regular appliance bulb and it still won’t turn off
Just replaced the underside bulb on my Whirlpool microwave, and this same thing happened. I know I fried the circuit board because it smelled like something burning. I quickly unplugged it. Didn't even think to unplug it before putting in the new bulb.
Where can we purchase one of those control boards (sites?). Just changed my bulb and now its doing that exact thing.
The Part# w10892389 - Search that, looks like amazon is sold out. The main site I use is partsselect if Wilmar is sold out of them. Whirlpool also sells them directly on their site. Keep in mind that they are expensive, so a more risky, but cheaper option would be to search eBay, or Facebook Marketplace. I know some techs that sell old used parts but if they have good feedback then it may be worth the risk and save you a bunch of money. Hope that helps.
@@ApartmentMaintenancePro Amazon has them back now but my gosh. $300???
@@chefcjnobles2423 Wow, I only paid $199.00 for the microwave.......cheaper to buy a new one.
yeap, better off either installing a switch on the power side of the bulb socket, or just going without the light until the unit totally fails. This is a horrible defect.
Customers need to think twice before buying the Whirlpool microwave- wmh53521hz-5. When the light won’t shut off the only way to fix it is to buy a new motherboard, and they range in price from $156 to over $300 online plus tax and shipping. Also $150 for service call to install it. And it’s an inherent problem in this Whirlpool model. You can buy a new microwave for $450 or pay that much for repairs or buy an LED stick up under cabinet lights for $12 to $18 as a alternative solution.
The original bulb was fine until I changed to LED. Now the light stays on when set to off. Is there a fix for that, or will all LED bulbs stay on?
I have a 2016 version of your microwave.
Yeah this happened to to me too. I suppose you could put some kind of resistor in the line. But I just left it as is.
Have a night light now. And it doesn't really use any power.
I just held down the stop /clear button for a few seconds and it worked
Excellent n genuineness
Thanks!!
I have same issue. Whirlpool but slightly different model.. Could the bulb be removed? As in general I don't see much of a need for this light.
LOL ok so the replacement control board costs $150 + . Junk microwaves, never buying Whirlpool again.
Ya still haven't figured out a way around it, it sucks. Someone in the comment mentioned wiring in a relay/switch under the microwave might be the cheapest/best alternative
Whirlpool sucks... have one just like yours and not too happy with it. Had a recall on it for fire hazard, and I was already having issues with the first one to start with. A few months or so after receiving a new one, the door sensor was acting up where it wouldn't send a signal saying that the door is closed, so I had to do some internet searching and luckily I found a video on You tube. And now, I'm here again trying to figure out how to get the light to turn off after replacing the bulb. It's like the company pushed the product out w/out thoroughly testing it.
All appliances have there faults, this particular one though is pretty annoying, wish there was an easier fix.
@@ApartmentMaintenancePro I might go for a Bosch since one of my family members has a dishwasher and stove and have been using it for five years or more with no issues. They just bought the over the range microwave and we'll see how it holds up over time.
The best fix is not buying Whirlpool junk.
I replaced board , but problem still remains.
How much was the board?
I replaced the board and the light still won’t go off. 🤔
Just bought a Whirlpool 1.9 cf the light was not bright enough for me I switche out to an Led & the bulb would not turn off . Switched back & works fine. Sept 2023. Angry now to dim for me.
I installed a toggle switch in series with my hot wire. It breaks the hot and I saved myself a couple hundred dollars.
Great idea!
What if the light inside, won’t turn off??!! Help :)
It may be your lower door switch. Does the microwave feel like it's latching all the way?
Why not use a relay instead of a Triac, to save a few cents? Then this problem could be avoided, and an LED would work. They ship new micros with 25-watt bulbs instead of 40 watts to save a few cents.
A relay makes a click sound, a trial is silent
Can't turn a relay on half way as you can a triac.

This happened to me 5 minutes ago...same microwave and everything. First microwave I've *ever* had this happen with...so weird.
Check out the top comment there’s a fix for it I’m waiting on a bad board with similar symptoms to make a video on it
Not weird, just Whirlpool junk.
M
Microwave above range won’t turn on
Ensure correct voltage to microwave
Control panels are “cheap plastic”? Well the manufacturer has got to continue making its money through parts exchange/replacement from the customer. I guarantee you that I will break off more than one of those clips when I take mine apart to change that motherboard if I can’t get my bottom light to turn on.
Thanks so much!!
That's too $$$ - I'm just going to leave the cover off with a LED bulb (a regular bulb was super hot)and turn it to the right when I need light and turn it to the left when I don't.
Sounds annoying
What garbage... A whole control board for a light bulb that wont turn off.
Thabks for making the video
There’s a cheap fix if you can solder on a circuit board check out my other video on this
Whirlpool is not what it was. Now the products last long enough for the warranty to expire then you get a middle finger.
Thanks!
Same problem with my whirlpool WMH53520CS-5 bought in 2016. Looks just like your microwave. Man I hope I don’t have to change the whole control panel. 👎🏻 Booooooo
Just get an incandescent bulb before you tear your microwave apart and work on it as if you or any of us are electricians. 😅
Just replaced with an Incandescent, same problem genius
This vido really help
This happened to me too recently. Whirlpool makes trash. I will never buy anything from them again.
Sir I think that was 5 screws 😂😂😂
Exact microwave I have!!!!
This is a shit microwave from Whirlpool. Two light replacements, first not unplugged, second was and two board failures. First was covered by the warranty, not the second. Shoddy product from Whirlpool
Ya not my favorite microwave for sure
Jesus. 9 minutes for a basic explanation. Might have been better as bullet points.
I’ll keep that in mind for future videos
Omg my bulb went out and then I replaced it - since then the bulb won’t turn off. So i had to remove the bulb. Thank God I seen this video to determine its the circuit board! wish me luck!
