- In this short video, I diagnose a non-functioning mini refrigerator, and fix it by replacing the PTC starter relay.
Here is the replacement part I used in this video:
4.7 Ohm 1 Pin Refrigerator Start Relay amzn.to/3xHZD6V

Thank you. I am legally blind and could not figure how to remove the relay. You video was the only one I could find that showed how to remove it. Thanks again.
Dude thanks so much for sharing this video! I have a mini fridge at my one-chair salon and it stopped running. Same thing happened to me! I opened my fridge to grab a drink for a salon guest and it was warm. I watched your video and fixed my fridge. Woohoo! The part was only $10. Thanks again!😊
Wow thank you so much. You helped me fix my wine fridge for only $9 and 5 minutes if work.
When this failed did it cut all power to your wine fridge?
This video helped me diagnose and repair my 9-year old Hamilton Beach mini fridge (REFHB43B). I needed the exact same part. The old starter relay was rattling.
Big thumbs up!
Thank you! I was looking for how to actually replace the relay switch. I have the same mini fridge
I just repaired my mini fridge with the same part. Note when you remove the old part, shake it and if it rattles, its bad. I opened up my old part and the ceramic disc inside was broken into 2 pieces, thus the rattle. Easy to diagnose, cheap and easy to fix vs buying a new one!
My relay switch was bad but had no rattle.
Yep, not all that rattles is defective and vice versa.
It may be possible to just clean the contacts. I cleaned the oxidation off the MOV disc and now it's working, even though I snapped off part of the MOV while removing it.
+1 did the exact same thing. thx
This video saved me. I knew my PTC relay was bad but didn't realise this was NOT a proprietary part as it's not longer available from Midea. I had advertised my freezer for junk and found this and ordered the part. thanks!
Still haven’t received the relay, once I do . I will install it and give you the good news .
My Magic chef dual zone mini frig would initially cool down to 39 & 50 but over a few hours would not stay cool. So I took out the start relay and it sounded like a baby rattle!! For $7 got a new one off Amazon and - now operating like new - thank you, thank you - saved me $$$$ as I was about to trash the unit and order a new frig. Thanks again Vance.
Thank you thank you. I’ve trashed many mini refrigerators. Thanks to you I can keep them longer. Your video works.
Thanks! Glad I could help!
thanks man, you honestly saved me close to a g note! I had 2 of same fridges. Pulled the relay out of the good one to check the broken one and voila! ordered 1 on amazon and a day later back in business.
Great video. The bad relay rattled which is common i guess....so i knew i had a good chance!
Cool!
Great Video Vance! Fixing to tear into a little Bud Light Mini Fridge I took a chance on and see if this fixes it. God Bless and Keep the Videos Coming 😁
Thanks Vance for a great learning video. I'll share your info with my appliance customers.
Project #22 on how to fix the Mini Refrigerator gave me the confidence to order the part & fix the fridge! Of course I had a helluva time getting the plastic housing thing back on--never really got it right--& lost the original screw in the process. Typical :( I found that the identical new part didn't have the exact same number as the broken part except for the top section: P6R8MC was a match. The bottom section, OR0504 was the number of the old part; the new part was labeled OR1001.The part looked the same so I ordered it despite numbers not matching. Thanks for the great quality of the video itself as well as the information provided. You saved me a lot of $$$!!! Keep up the good work, it is much appreciated by a lot of us wannabe DIY-ers.
Can you tell me how you got your plastic cover off? I can't for the life of me get mine off and I've taken the screw out - nothing else is there, but something is holding on!
My wife spend a more than what I thought a custom 49er mini fridge would cost and it died. Thanks to this video, my wife's present is no longer a giant paper weight. It's working again thanks to your help. It is greatly appreciated.
Awesome!
Great step-by-step, and it totally worked for me! Thanks!
Thanks a lot. I had given up on my midea refrigerator but you helped me fix it. I didn't actually replace my start relay, i rotated the ceramic in it like someone suggested in the comments and everything is ok now.
That's what I'm planning on doing. I wonder if you can buy like 5 of these ceramic disks for future use?
Thank you for the tip. Fix my mini fridge from going to the dump and having to buy a new one. The relay was the problem. Replaced with amazon purchase. Saved me money.
By the way my relay didn’t Rattle inside old one. but it was the issue with the replacement part fixed it.
That's great!
THANK YOU!, THANK YOU!, THANK YOU! I wasn't sure of how to take this off until I watched your video. Thank You Again.
Wow, thanks man, $158 on Ebay, and free shipping!! couldn't believe it.
Thanks for the video man! Ordering the piece right now for $7 hopefully that’s the issue with my mini fridge 💯
Good luck! Hope you get it fixed!
Thanks for the tip. Repaired my Magic Chef bar fridge for $16 vs a $600 replacement!
Awesome! Glad you got it fixed cheap!
Awesome vid! I was wondering how that part came off! Thanks!
using your video, I now have a working fridge again.... Thankyou
Great! Glad it helped you!
Brilliant educational video. Thank you.
Awesome. You just helped me figure out my refrigerator problem. Ty
great clear informative video thanks.
Thanks for the video. I switched out the relay but must have different issue. The compressor seems to start for 2-3 seconds and clicks off. Same issue with old and new relay. Not sure what that could be. At least the fridge light works :) I've the same fridge as in the video. The overload protector rattles so gonna replace that. Assuming rattle means broken.
My part is P6R8MCor0605
Model number
Magic Chef
MCBC580DBT
2582
PS I got both the overload part and the relay but it's so hard to see in there and i was glad your video showed it with plenty of light for me to see how the two parts went together and pushed on to the compressor.
Made it easier to know where they go, but now with bad diabetes hands I am going to have to try to fit the parts on and put the cover back. Thanks
thank you! in our frost-free type, the problem was also the PTC.
Just got a free mini fridge due to the exact part. Ordered both in a set. Thanks for sharing
Where do you order the parts? i been looking and seems to be harder to find them now.
@@hwarangdrac I ordered on Amazon. Was very inexpensive and got both parts in kit. Fast deliver and easy access for repair.
Hi! Nice work! I was just about to trash it and fixed mines!! Yay!!! Only thing is...what noone is telling the ladies is 1. where to put the wires back if you forget to take a pic and most importantly after the install if you plug it in and you still don't hear the compressor... turn you dial (inside the fridge) to zero and then to your desired setting to reset it. Sfter I did that mines then kicked back on. So happy I am back in business!!👍Thanks for your awesome help!!
Cool. Glad to hear you got it fixed!
In this model switching the wires wouldn't make a difference, since it is 120VAC.
Yeah, I just completely destroyed the plastic housing just trying to get the wire off of it (in this video it's blue and you don't show it's removal). It won't wiggle off or let me pry it off. I don't know what I'm going to do except maybe cut the whole danged wire off and try to find a fresh clip while I'm at it. Maybe melt it off. Fire's always good, right?
@@calciumchloride710 my fridge died earlier this week, and yesterday finally found videos of how to fix. I to did that same exact thing you did. I couldn't find any videos anywhere on how to remove that plug, so I pretty much got pliers, and broke up the entire rely just to remove that plug. It's a tad bent, but should be ok sliding back onto the new one I ordered coming in today. It would've been nice if it showed how to remove it. After destroying it. It would've impossible to slide that plug off. There was way more attached to it.
Great video! I did this yesterday! The schematic shows this is an RSIR (Resistor Start Induction Run) compressor with no capacitors. It uses a PTC resistor to provide Start winding current and then, as the resistance increases, decrease the Start winding current to prevent it burning out. It is probably a 4.7 ohm PTC. I found this video while attempting to repair a slighly larger mini-fridge that had the same symptoms. The compressor got very hot and hummed but wouldn't cool. I believe it was failing to start because of a failed PTC and just sat there with current flowing through the Run winding but not rotating, until the Thermal Overload cut it off. The cycle repeated when ever it cooled off enough to reset. It was drawing about 9 amps while sitting and humming with an LRA rating of 11 amps. I checked the PTC device and was reading about 60 ohms while it was supposed to be 4.7 ohms when cold. I disassembled it and found a coin shaped PTC sandwiched between 2 flat spring contacts. One side showed signs of arcing on the PTC disc and its contact. I sanded/scraped the PTC and the contact and got the PTC down to 11 ohms and reading 9 ohms when the device was reassembled. I reinstalled it to check my hypothesis. The mini-fridge started right up and is showing its rated RLA of 1.3 amps. The new replacement should arrive in 2 days but the fridge is still running.
Thank you for the Technical information Henry. I hope this works for me as well 😁
Great story, Henry. This video is very good, but to actually prove the diagnosis before shooting off the parts cannon takes very little time and is so much more satisfying. I've been reviewing refrigerator circuit drawings, and their engineering is no less than fascinating. The downside to those PTC devices is the way the resistor stays in the circuit for the duration of the cycle, drawing power and heat that has to go somewhere. Even though there are no moving parts, it is no surprise the heat eventually gets to them.
@@spelunkerd I wonder if you can order just the ceramic disk (and get like 5 of them for future replacements)
S
Smh!! Crazy how such a cheap lil part that can b replaced can save u a whole new fridge! Thankz-!
Great video! My mini magic chef fridge is doing the same thing . I’m going to order the same part and hope it works . Thank you!
Glad the video help you out! Check out the electrical diagram in my video at 1:03. It could also be the overload protector or thermostat. They are also inexpensive parts to replace. I recommend some quick diagnosis before ordering a replacement part.
My magic chef has a light on but compressor not running any idea of what this is?
I was able to open the starter relay and rotate the ceramic contact disc 90 degrees which provided new contact area for the leads. May need a new part in the future, but works for now.
mate your a legend mine broke this morning and just did what you said and it worked thankyou soooo much
@@fuckadodarday No worries!
BROOOO I JUDT DID THIS AND IT WORKED YOU SRE A FUCKING G UNIT
@@Setttle I know, right? I've been picking up "Broken" mini fridges, fixing them and selling for profit!
..thanks for sharing,..thought you may have mentioned the overload could be checked too.
However, the starter relay was the component that was bad. In my case, it was the overload that failed.
That was due the cooling coils being completely clogged with dust.
Most helpful. Thank you. 👍👍😊
Great video I will try the same repair
I have a Hisense mini freezer would the way of removing would be similar.
Great video
Awesome video, very useful. 😎👍
I plan on checking my mini fridge tomorrow
Excellent video Vance. I fixed mine yesterday, but the compressor didn’t come on. So I came here to see what you did. Thanks to Mrs.Shakur all I had to do was press the reset inside the door.
Yay! Hi 5
That's awesome! And thanks to MrsShakur for a great tip!
Thank you great video saved my fridge
Good job mate 👍
I cant believe this , I bought the same exact mini refrige same color & brand from Homeport was display unit was on the floor had some dents on it here & there ..the guy sold it to me for $50 i bought it real quick is F*N BRAND NEW & is worth it $150 new in box ...so i just plugged it & works like a charm well is BRAND new ...so i know what gonna do if is stops working. Cool thanks
Thanks great video ....simple and direct . I subscribed !
Thanks!
Thank you. Question? My refrigerator runs good temps,but the freezer goes from 0° to 26° then back to 0° in a day. What could be the problem? thanks for any help. Chuck.
Thanks for the video.
Nice video, thanks.
Super thanks to you man great video
Thank you so much!!!😊
Thank, very nice your help,
I have a Haier freezer that "just stopped working" and we lost a bunch of frozen food. The schematic on the back of my freezer (HNCM035C) looks nearly identical to your fridge. As my unit does not have a starter capacitor, and it "buzzes" when plugged in, it must be the PTC (Positive Temperature Coffecient) starter. From my read of the schematic, the "S" coil, S=start I assume, which is connected to the PTC must get current to start the compressor turning. Once the PTC heats up, the resistance drops and nearly no current flows through the start coil, and the main current flows through the "M" coil, M=motor, again I assume.
I watched your video to see how this unit comes off. I figured it was "just pry with a screw driver" but I didn't want to use "enough brute force until it came off" without first knowing that is the right approach.
Stupid $10 part cost us a 3/4 full 3.5 cubic ft freezer's worth of food. Wife thinks I'm nuts trying to repair this. It can be a "backup freezer" for when we defrost our main freezer. Trying to decide if this is worth fixing before we buy the replacement. The decision is "do we have the old one hauled off for disposal, for fix it?" I think fix it is possible.
Your video agrees to other's on this topic. Very useful. Thanks for sharing!
Awesome video
Thanks for the video. Question: I am getting the rated voltage (220v) out of the relay when I put a multimeter on it: does that mean that my relay is ok?
Just the vid I needed👍🏽👍🏽
Which overload would you suggest?
We have a magic chef mini fridge and it started clicking so we took the relay part off it had like 4 things plugged into it so it was different then yours as yours only had one plugged into it we are trying to find another one to order nothing was rattling in the start relay but we read it still could be why it quit cooling? Any ideas I sure hope we get everything plugged back in correctly?!?
Thank you so much this video help me out
Good job !! Love it
Thanks for watching!
JPQ relays are very specific, make sure to get the correct number of pins
I replaced the starter relay, it ran about an hour then stopped. What do you recommend?? Thank you!
Your a legend mate. Watched your vid, took the same parts to the local parts shop, plugged it all back together and boom fixed. I replaced the Starter Relay and Compressor Overload Protector. It was prob just the C.O.P but might as well replace em both while I was there.
Thank you! Glad you got it fixed up!
I have a mini cooler fridge without the freezer compartment. Lately, it started making gurgling and humming sounds which is quite annoying at nights during sleep. Noticed the condenser is watery and dripping water, so I cleaned the drainpipe which was clogged and wiped the condenser. Turned it back on and the gurgling and humming sound can still be heard loud and clear. Also noticed that this fridge does not come with a fan to cool the compressor which seems quite hot to touch. The fridge is otherwise cooling good. Any suggestions? Thanks.
What does the little piece on the single pin above the starter relay do? Also has a single wire plugged into it.
Elexelent video ,thanks!!
I have a question, I replaced both the overload and start relays, and my wine chiller s still doing the same thing, the compressor turns on, then clicks off after a moment, I filed down the female connections a bit but that didn’t help, any suggestions would be much appreciated.
Can I install 1 pin relay eventhough my fridge starter relay has 3 pins?
So that other piece, the overload protector, does anyone know if these go bad? I can shake it and it rattles. But it may just be the metal prongs I side rattling. The starter relay does not rattle when I shake it. There's no clicking on the relay when I plug it in
Thanks for the video, i found one WDW 800 from cuisinart and just wondered if i can make it work (love tinkering with stuff) any recommended place to get the parts?
I took overload relay it has part #s on it & googled & nothing comes up..how would you order your overload relay,i need to replace that bc mine is rattling,my start relay doesnt rattle
I realized after I received the relay it was a 3-pin type can i just not use the 3rd pin or I need to get the 2 pin.
Any chance you can tell me what to do? I unhooked the ptc without remembering where everything goes and now that I have replaced it I seem to have 2 extra wires and cannot figure out what they connect to. I have a 2 pin ptc, 2 white wires, 2 black wires, both of which have one wire with a "boot" type cover and the other with a smaller connector. I have put 1 white with boot and 1 back with boot back onto the 2 pins, but don't know what to do with the other 2 wires.
What is the round tube on the left? Is that replaceable?
Hey Vance great video. I have a Galanz fridge and the relay switch has 2 pins on position 1 and 2. I can't seem to find the exact match anywhere. Any suggestions???
Thanks a lot!
Did you get the cover removed? Mine wont come off either the clip seems to be released from the side but nothing woks
Any tips to remove the cable from the relay I’m afraid im gonna break the cable
I gonna install my relay tomorrow!
Thanks for watching! Hope this helps you get your fridge fixed!
have you done a defrost sensor? with en e4 error
잘 보았습니다. 오버로드 는 문제 없었나요?? 고장나면 흔들면 소리가 난다고 하던데 그런가요??
If the compressor is working, but makes a water sound, and dosnt cool fridge enough... will replacing the relay fix my issue?
the overload on mine is labeled Wanbao 2667P-6 DRB16N61A1 I cant find it anywhere. are the overload protectors mostly compatable?
I didnt have the same luck.It kicks on but shut back off.What that means?
Wonderful
Great video
Thanks!
Hey, mine started but it’s constantly tripping. Any ideas
Hi. You know what, I've got 3 relays: a starter, overload, and the third one looking similar to the overload one. So, I don't know how to connect them all to my compressor of a Japanese fridge. Please, help me if you know how to do it. I'm confused having 3 of then insead of 2.
hardest part for me is getting the plastic cap off on a RCA mini fridge. I cant seem to get it off and i dont want to hurt the wires or anything else. i need help. rca model rfr322-e refrigerator
My fridge door was left open for maybe 9 hours and 2 days after it's not cooling. What could be the cause of that. The compressor is clicking on and off.
I have many mini fridge and then it's stopped working but when I punch the knob/light housing it will start back up what is issue is that
Hello do you know where can I find MS2-4 7L-01
Hi.
My compressor also gets warm. I replaced the ptc. All it does is click every now qnd yhen. Compressor stil gets warm. But doesnt turn on.
I have a frigidaire refrigerator mini the model they say not there it takes three-pin and a new white thing that goes on first it looks like it got hot the on starter have have the same number as my three-pin. than k hope i can
Hello,
I was given my mini fridge . On the left side of the black box the copper tubing doesn't attach to anything but the black box. Is that ok or not?
My mini will not cool. I think the relay is bad. I'm getting ready to take it out and check it.
Thank you 👍❤️
Can this cause an intermittent problem?
What is function of running capacitor in refrigerator? Can it fix with national rely? Can it reduce fridge watt?
The housing on mine is very difficult to remove.
I took apart the QP-2 4.7 2-pin relay to a Galanz 3.7 mini fridge (2 door), found out the white wire is the main wire goes across both pins, the black wire is a stand alone-it does not connect to nothing...so when your 2 pin relay goes out, I recommend a 1 pin relay [connect white wire only]...the black wire needs to be wire capped...To find this part try Ebay its cheaper 👍
Hi i have a galanz 3.5 and the relay has 2 pins (2 , 3). It has 2 black wires to one pin and 2 white ones to another. So your saying the 1 pin relay will work?
@@charliehorse11 I have this same issue. Any help out there?
Great video. I struggle to recover the cover to access the overload relay. But the parts number is not avaiable or not found on search engines, but the results have parts that look the same but different number. Will it still work or could cause damage to the unit.
Looking for ZHB54-120P4-7, result is for ZHB35-120P15 (looks identical on the outside).
@Tony Tsai I have the same problem, did you end up trying ZHB35-120P15 and did it work?
