My god this video was one of those rare gems. Straight to the damn point without any stupid history. Plenty of cuts showing the pertinent information and how to actually fix it before falling into a coma from boredom. Bravo sir, bravo.
Whether or not this helps me fix my dehumidifier, thank you for sharing. Fantastically clear, very helpful vids like these deserve 10k likes at a minimum.
Very easy to the point video for we inexperienced people, Thank You! Now if I just understood the 'technical words' I wouldn't be so nervous to try this fix. You just gained a like and a new subscriber.
First, a very informative video. I bought a brand new Frigidaire dehumidifier early 2022 from BJ's. It was manufactured October 2021. We didn't buy a warranty. A couple of weeks ago, it gave EC error. I turned the power off and on and the error went a way. However, it would collect any water. I called BJ's but was told that the manufacturer warranty was for one year and because I didn't buy extended warranty, I have to pay for cost of repair. I then started looking online and one of the videos that I found very useful was yours. So, I followed the instructions in your video (every step) until I thought it would need refrigerant. Unfortunately, I didn't see anything on the compressor or other places that I researched to find out what kind of refrigerant if any the new Frigidaire uses in their dehumidifiers. I went ahead and added R-134a until it got to end of the blue zone. After a few hours, I saw a few drops of water in the bucket. It was clear that it didn't work. I noticed that regardless of the humidity in the basement, it shows 55 and never changes even after running it for 4+ hours (no water). I have another Frigidaire dehumidifier running s few feet from the one that doesn't appear to work and the bucket is full after a day or two. I hate the idea to get rid of what I paid $300+ just a year and half ago. Any suggestions?
The newer units I have bought from HD are labelled that they use R-410a. Mixing car refrigerant with the R410a probably doesn't compress and evaporate correctly in the system they are touchy like that.
Very helpful. I wasn't aware they made piercing valves for refrigerant lines. Ordered one today. Will save $$ on my dehumidifier repair. Thanks a bunch!!!
@@LBizKid04 Yes. Those piercing valves aren't great either. Preferably, you would evacuate all of the refrigerant, solder in a proper fitting, and then vacuum and recharge it, but with these, it isn't really worth all of that. But just expect it to continue leaking, so you are going to have to keep filling it back up.
@@LBizKid04 The way they work is that they have a small pin, which punches a hole in the copper tube, and there is a rubber o ring around where it punches the hole which gets pressed onto the copper tube. Originally, without the piercing valve, the system is 100% sealed and all of the fittings are soldered together (or brazed). but with the piercing valve, you are holding the pressure purely with a small rubber o ring, which very rarely seals 100%, so you will almost always have a slow leak. Piercing valves are really only designed for temporary use or evacuating a sealed system so you can then install a proper service port which is soldered in. Although, in this case, there is already a leak in the system which likely formed due to corrosion or a manufacturing defect, and these appliances aren't worth the time or tools required to do the job "correctly", so a piercing valve is fine, just expect to have to fill it back up every now and then.
@@LBizKid04Another fun fact is that if the dehumidifier is designed for R-134a (which most of them are), you can use R-152a which is just the "canned air" which is used for dusting out computers. It is actually a gas which can be used as a refrigerant. It is a drop in replacement for 134, and cost a lot less, so if there is a leak and you have to fill it up every now and then, it will cost a lot less in the long run.
😀Thank you sir! I took mine apart and that was the problem, more specifically the wire connecting the thermal switch to the compressor as it was corroded off. I removed the old wire, cleaned the contact, soldered a new wire and end on it then I connected it back up and PRESTO! it works again! 😀
Brilliant! Thanks SO much. I was told "they are disposable, get a new one". Not my styles, this will help tremendously and it actually even looks like my Danby DDR4007EE so I am excited to give it a go. You're a godsend sir ... TYVM Lou.
Sir: You are a steely-eyed rocket genius. Great info and I knew nothing about the switch you replaced or that these units can be recharged. Thanks again.
Went through about 50 videos before getting to yours. First one to fully explain which line is which for the refrigerant and which one you put the valve on. I was pretty sure I had the right line from doing a few fridges but wanted to make sure before I pierced the line.
Good video. Bought the adapter to allow refrigerant refill. Installed adapter. Before adding refrigerant, wanted to make sure it needed 134A that I had. Found a little label stating it used R-22. R-22 not widely available anymore nor recommended. End of project. Now another $42 to recycle it after all. I would update the video with a comment about refrigerant before showing how to add it. Thanks.
Bullet valve... Exactly the thing I've needed every 1.5 years when my dehumidifiers break. Thanks for the info. These aluminum units leak their refrigerant out after a year.
this was actually helpful, thanks! I may have accidently thrown out a dehumidifier a couple years ago. I didn't know about the piercing method for the pipes. I was looking for a fill port like on cars and assumed they intentionally made it not serviceable, whoops!
@@LBizKid04 That piercing adapter has a special seal that is supposed to keep it sealed. The piercing adapter stays on the dehumidifier after you are done. How long the seal properly seals the system is another question. My guess, not that long. That is why those systems are supposedly closed. Also, if your refrigerant is "low", you have a leak someplace in a closed system like this.
Thank you sir for giving us the great information and to fixing it in the most cheapest way by us. It is soooo simple to do it. Once again my sincere Big Thanks Again.
Thank you for the video, great information. I had planned on throwing away three old units away that was here when I moved in, but I'm going to open them up and see if I can get them working again
i have this exact model of dehumidifier.. i'm now happy to see how my repair guy is going to fix it! lol everything about this DIY seemed scary to attempt as laymen. But thanks anyway! Thank you for teaching me I need a professional. lol
Cool repair. Was going to attempt this, but most of the newer dehumidifiers use r410a rather than r134a. These 2 coolants are not interchangeable and r140a is extremely difficult to find for the DIYer and even if you can find it, a small can costs about as much as a new dehumidifier.
That little gas tap thing is amazing. I never knew they existed. I have a water dispenser where the thermal overload keeps tripping every few seconds. I tried to just replace it, but the same issue exists. I wasn't sure what to do beyond that.
You might try running vinegar through it. They build up calcium just like coffee makers. The tubes get restricted and the water can flow fast enough and that can cause overheating
@@HowToLou sorry I should have been clearer. It's a hot/cold water dispenser like you find in an office. I guess many would call it the water cooler. I don't use the hot mode, just the cold mode which uses the compressor. Everything seems to be flowing okay.
Ok got it, so it cools the water. That should be just like the dehumidifier then. I would try exactly the same steps I did. Wire around the overheat sensor to get the compressor going. If you can’t feel it vibrate, it’s not running, and I guess it’s possible the compressor is dead, in which case the whole thing is junk. It’s probably not worth replacing a compressor. If you can get it going, and you’re not getting pretty hot on the hot side and pretty cold on the cold side, you probably need to add refrigerant. Honestly, that’s typically what happens to these things. The refrigerant slowly leaks out over years of time
Video was so helpful! GREAT JOB!! I have 2 questions: First: How much r134a should you put in? Do you stay in the blue area on the guage? I am worried about putting in too little or too much. Second: Do all the coolant cans have the same top? I am wondering if the cans are interchangeable with the guage hoses. I was not able to find all three parts (bullet peircing valve, guage and r134a) sold together. THANK YOU SO MUCH!!!
You add coolant slowly until the coils frost over, then more until they loose the frost, and you are done. I have the parts listed in the description of the video
Interesting I have two of these same model and design one is large and the other is a small version of it great video but how do I know what pressure to fill the freon to?
Alot better than the last video I just watched for like 30 minutes and all he did was talk about what a piece of junk it was and gave a couple hints of what maybe the issue with it. lol
Thank you for letting me know what to do and save my dehumidifier. Quick question fella, Why do some dehumidifier really work super and put out loads of water?? Design is better for a commercial unit as compared to a home unit????
@@HowToLou What would make the unit super great on an average dehumidifier in the 20 to 30 pint range. This one unit outperforms the other three units I have. The compressor seems to run way more than the others, is what I noticed. Thanks fella.
Exactly what I said above. Dehumidifiers work by moving air across cold metal fins, where the water condenses out. More fins mean more cold surface area for the water to condense. This also means you can run the fan a little faster. This also means your compressor needs to work harder to keep more fins cool. If you really want to understand the difference, you need to open up both units and compare the components. And I suspect you will find all the difference is I mentioned in my first response.
My model machine takes R410A refrigerant, which has been discontinued for environmental reasons, is there some other type that I can use? My dehumidifier is a Delonghi DD30P
This was beyond cool to watch..I didn't even need a repair, came across video after looking for filter. I bought mine from a yard sale so no instructions
Great info Lou! And exceptionally well-done video! Thank you! No to search and see if you mention what to do if the unit blows but gets blocked by ice build up! Help?
HI Lou. This is a great instructional video! I have two dehumidifiers, a Fridgidaire and an Amana, that I run in our basement to try and keep the mold and miidew in check. They are both getting up in age and I have to take them every year, or every other year to someone to refill the refrigerant. Obviously, they both slowly leak the coolant, and I know it would be cheaper to just replace them, but I'm the kind of guy who hates to throw anything away. Hopefully, I can use your excellent tutorial and fix these myself. What do I have to lose? :) Thanks for sharing.
After you added refrigerant, you still had frost showing on the bottom coil and the line going to it. Add just a touch more, until that frost flashes off, and you've recharged it correctly. I have the Keystone 50 pint model and it has refrigerant 410A. Did you mix 134 with 410A?
@@k30v6xxzeapm The problem most will find is that buying what you need to keep one of these going is just as much as buying a new one. OBTW, despite its rave reviews, my Keystone 50 pint unit is 2 years old and they will not honor their warranty. You're led to believe the refrigeration system is warranted for 5 years - it's not! They could care less.
This is correct. The person who made this video really skipped over the fact that 134A may not be the correct refrigerant for your model. Older units used to use 134A but most of the units people have are 410A. I don't think people can even buy 410A without a license. There is an entirely new refrigerant that is not a fluorinated hydrocarbon which will be in dehumidifiers soon. This will make adding the wrong refrigerant even more dangerous.
@@ianwarren5297 Even if you were to buy 410A, it’s expensive to buy when you only need a few ounces and then you need all of the stuff to add it. I got nowhere with the idiots at Keystone and bought a Hisense ( Lowes). At least they give you a 2 year warranty.
Grreat video! I have a 2016 dehumidifier. The thermoswitch is not where you show it. Looks like it is in a cylindrical unit in the electrical box area but not sure. My compressor works for a few minutes then turns off. Where would the thermoswitch be? I assume I will need to add more coolant (410a).
Very helpful, sound advice in general but if you need to add refrigerant you should *not* be adding R134a as that is automotive refrigerant with a different chemical composition to the R410a used in most residential applications including in most dehumidifiers. Some older units use R22, so it's always best to check the label which is usually on the back of the unit and it'll say what refrigerant it takes and the total refrigerant capacity. These have a very small refrigerant capacity, usually between 5-10oz, so they are very easy to overfill and if you do it'll cause refrigerant pressure to be too high, wearing out and eventually damaging the compressor.
@@charlesquinn7622 I know, I mentioned in my comment to check the label. R410a is what's used in the overwhelming majority of dehumidifiers manufactured in the past decade, though. I know there's a few that use R134a, it's just not the norm.
@@deyeatdapoopoo7582 Just saw this video, can't find r410a in amount needed, can 134a be used instead safely or do you have a vendor recommendation for 410a
that red wire when connected to main board and overload it trips the breaker. when disconnected ,blower works no problem but not the compressor. is it board or that overload? problem?
You can try running power directly to compressor to see if that trips the breaker. If so, bad compressor. If not, bad board. But can you even buy a new board? It may not be worth diagnosing, if you can’t buy parts to fix it.
My 32 y.o. Creda dehumidifier has just stopped dehumidifying. The pump is still running and so is the fan, so I'm guessing it's low on refrigerant (don't they have a pressure safety switch?). Probably time for a new one anyway!
My god this video was one of those rare gems. Straight to the damn point without any stupid history. Plenty of cuts showing the pertinent information and how to actually fix it before falling into a coma from boredom. Bravo sir, bravo.

Do you leave the bullet piercing valve in place?
Absolutely. It actually punches a hole into the tubing, so if you take it off, all of your refrigerant will quickly leak out!

so basically, 1.) the refrigerant escapes, and then 2.) the compressor over works but then eventually blows a fuse?
Exactly
Thanks ! Any ideas on how to find the gas leak ?
Wasn't this unit recalled? I have a soleus 45 pint dehumidifier that I just found out was recalled quite a while back. They are still refunding
Will the cover fit back on over that port you added?
After you added refrigerant, you still had frost showing on the bottom coil and the line going to it. Add just a touch more, until that frost flashes off, and you've recharged it correctly.
I have the Keystone 50 pint model and it has refrigerant 410A. Did you mix 134 with 410A?
Agree, It still little low on refrigerant, it flashes too early after capillary, there should be no signs of frost on warm day after ~5min.
@@k30v6xxzeapm The problem most will find is that buying what you need to keep one of these going is just as much as buying a new one. OBTW, despite its rave reviews, my Keystone 50 pint unit is 2 years old and they will not honor their warranty. You're led to believe the refrigeration system is warranted for 5 years - it's not! They could care less.
This is correct. The person who made this video really skipped over the fact that 134A may not be the correct refrigerant for your model. Older units used to use 134A but most of the units people have are 410A. I don't think people can even buy 410A without a license. There is an entirely new refrigerant that is not a fluorinated hydrocarbon which will be in dehumidifiers soon. This will make adding the wrong refrigerant even more dangerous.
@@ianwarren5297 Even if you were to buy 410A, it’s expensive to buy when you only need a few ounces and then you need all of the stuff to add it. I got nowhere with the idiots at Keystone and bought a Hisense ( Lowes). At least they give you a 2 year warranty.
Well, my Hisense is out of warranty and only part of the coil is cold enough to do anything. You just can't win with these stupid things!!!!!!!!
If you need to add refrigerant that means it has a leak correct? Won’t it all leak out again?!? Is there a refrigerant system sealer?
Any idea how much running pressure should be will recharge r4010
Charge until coils frost up and then a little more until they unfrost.
Man, that was a good video.
Grreat video! I have a 2016 dehumidifier. The thermoswitch is not where you show it. Looks like it is in a cylindrical unit in the electrical box area but not sure. My compressor works for a few minutes then turns off. Where would the thermoswitch be? I assume I will need to add more coolant (410a).
Great video , my compressor doesn't seem to vibrate but it just got so hot couldn't touch it?
Great video. Need a little help with details on the bullet valve and where to purchase one. Thank you!
All parts are listed in video description
Found it - thank you!!!
Very helpful, sound advice in general but if you need to add refrigerant you should *not* be adding R134a as that is automotive refrigerant with a different chemical composition to the R410a used in most residential applications including in most dehumidifiers. Some older units use R22, so it's always best to check the label which is usually on the back of the unit and it'll say what refrigerant it takes and the total refrigerant capacity. These have a very small refrigerant capacity, usually between 5-10oz, so they are very easy to overfill and if you do it'll cause refrigerant pressure to be too high, wearing out and eventually damaging the compressor.
My Waykar brand dehumidifier uses R134a so really you need to check the label that's on the back of your humidifier...it's clearly listed there.
@@charlesquinn7622 I know, I mentioned in my comment to check the label. R410a is what's used in the overwhelming majority of dehumidifiers manufactured in the past decade, though. I know there's a few that use R134a, it's just not the norm.
@@deyeatdapoopoo7582 Just saw this video, can't find r410a in amount needed, can 134a be used instead safely or do you have a vendor recommendation for 410a
Super easy ! I’ll go buy a new one .. great video though!!
Great video , very informative ....My dehumidifier is showing 410A how has the 134 been doing since its been almost a year...
I was wondering the same, they are not meant to be equal, but if the 134 is just 15-20% of total,(guessing from top off) I wonder if it matters.
that red wire when connected to main board and overload it trips the breaker. when disconnected ,blower works no problem but not the compressor. is it board or that overload? problem?
You can try running power directly to compressor to see if that trips the breaker. If so, bad compressor. If not, bad board. But can you even buy a new board? It may not be worth diagnosing, if you can’t buy parts to fix it.
Well done sir.
Thank you, Lou. Do you have a website? Where are the links for the parts/supplies for the fixes you talk about?

Great video can I use r134 on r22 portable dehumidifier?
My 32 y.o. Creda dehumidifier has just stopped dehumidifying. The pump is still running and so is the fan, so I'm guessing it's low on refrigerant (don't they have a pressure safety switch?). Probably time for a new one anyway!
