One morning i opened the refrigerator and noticed it wasn't very cold inside. The light was on and the water and ice worked, but it was luke warm inside and the compressor wasn't turning on. So this video is the 4 things i check and was eventually able to fix the problem. It wasn't the compressor, but the compressor start relay. The compressor and capacitor were still good. Just buy a new part and install it.

Thank you! Because of your video I was able to diagnose and fix my freezer. I'm a 67 yr old woman.
Absolutely gold!
I'm a refrigerator tech and I must say your explanation is on the mark ..welldone
Our Whirlpool refrigerator stopped working after a power outage.. the lights & fans come on but the cooling & freezer isnt working. Could it be a bad Start Relay or Capicator? Or could it be the main circuit board? Thanks

🤣🤣🤣 She said she don't give a fart we are getting a new one. So someone else will appreciate that you fixed it.👊
My garage refrigerator stopped working. Fan was working but not the compressor. I followed your instructions and ordered a relay switch and capacitor from Amazon for $20, and now it's working fine.
Thank you so much. I didn't know how much a repair guy would charge, so I was thinking of trashing it. Thanks to you, it's working now.
Repairman here. Would have most likely cost $150 - $300 depending on your area. Somewhere in that range. Glad you got it fixed!
I had a guy charge me $300 saying he gave me a deal wish i saw this video cuz the part was only 8.99 on amazon😢
@@Queenjess69 he probably did. I wouldn't doubt if some repairmen charge 5-600 as that's about how much all the food in there would cost.
You are one of the best tutors ever, everything you presented was straight and easy to follow! Please give us more videos! Thanks.
Best self help video I've seen so far! Straight and to the point. Thanks for showing how to check things with the meter. Super helpful!
You saved my refrigerator from the landfill. Very grateful for your post!
This was a good video explaining what to check in a no cool situation in a refer. The only thing I would add as a 40 year refer tech(Whirlpool/Sub Zero) is that the compressor sounded noisy after the start relay was installed. The compressor may be going bad and a good check is to put a amp probe on the wiring and see what the compressor is drawing in amps. Overall this video tells you what to look for. Great to see these type of video's helping consumers
@Salvadore Orozco Great question I look for about 3 or 4 amps on startup and about 1 to 3 amps on run. If you have higher amps the compressor will probably fail shortly I also carry a hard start kit which may extend life of compressor
Salvadore Orozco There should be a sticker on the compressor with information including the RLA, that’s the “ rated load amps”, that is about what you should see for current draw for that particular compressor. Invest in a clamp amp if this interests you, it’s a good tool to have along with a VOM. See the difference between 40 years experience and 45 years experience.
Joe Yelda Wow are you off, start amps are much higher, as a rule of thumb start amps are around 5 times the run amps, and they are usually given on the label on the compressor.
Hi Dave! I watched the video and you are really good explaining how to fix!
I have a whirlpool fridge!
My frizzer works fine (bottom frizzer)
But the refrigerator doesn’t work!
Do you think my fridge problem is the same as yours?
Please LMK
Thank you 😊 BTW in case you think I didn’t writing ✍️ well
English is not my first language😊
@@nunyabusiness6746 I’ve only got 38 years of experience. I have learned that you cannot use the RLA value to determine the correct operating amperage. RLA is a mathematical calculation required to meet Underwriters Laboratories Inc. (UL) approval only.
You can use the amperage rating for that compressor either located on the compressor or from the manufacture. Since the start windings are only energized for a few seconds, there is no real near to determine the amps at start for troubleshooting. The Amperage of the run windings more useful in troubleshooting The ohms of both windings are also useful. In fact, ohms of the start windings is ideal vs amps of start. If a compressor is running, the start windings are fine. Easy peasy. But what do I know with only 38 years experience.
Best video I’ve seen so far . Great job explaining how to troubleshoot a refrigerator not working properly.
With the help of your video it saved me spending $2000 on a new fridge. It was the compressor start relay. Thanks for the help much appreciated.
who the hell spends $2000 on a fridge?
@@ThePolaroid669 People that have $2000 to spend on a fridge....
Thanks my man. People like you that help other people are very much appreciated.. Your the best.
Thanks so much! Your diagnostic steps helped us fix a similar GE frig. We’re very grateful since repair service is very hard to schedule due to COVID. Feels so good to fix it ourselves!
Great video. Your step by step approach is easy to follow and understand. Thanks for putting this together, it really helped me figure out what was wrong with mine.
Dave Wirth, this video really helped me. Was able to diagnose and fix my 15 yr old LG fridge for 10 bucks. It was a bad starter relay and protection combo. The multimeter tests you showed were super helpful. You saved me a couple thousand bucks for a new fridge.
This video gave me hope. My old refrigerator died less than a year ago, so my local veteran's outreach group had a member who had a used refrigerator sitting in his storage unit taking up space, so he donated it to me, for which I am eternally grateful. Then a couple of days ago it suddenly stopped cooling--lost probably $200 worth of food in the freezer alone. It's a nice late-model Whirlpool side-by-side, too. I think having a repairman come look at it would be preferable to trying to replace it--I could never afford to replace a fridge as nice as this one. This video makes me realize it would be worth having a professional look at it (I'm elderly and very disabled) rather than buying another used fridge. It could be something as simple as the mice chewed through a wire or a broken relay. Thank you so much!
Great Job. Coming from an leading electrical engineer in the industry for 30 years.
I'm with Minh Leu... you are a fantastic teacher. I've seen factory videos on how to do something, and your video was better. You really have a talent for putting yourself in the mindset of the audience and helps us understand everything you were teaching us. Thanks so much! (Now, if you'll just do one or replacing the AC compressor in a 2007 Saturn Vue, you can take the rest of the day off.
Thank you! Your diagnostic steps helped me fix a similar GE frig, since repair service was very hard to schedule right now. Feels so good to repair it ourselves!
It’s Saturday evening n my renter calls about their refrig not cooling. Your vid was perfectly laid out for troubleshooting the problem. Many Thx Dave!
Great Job Dave 🧰 This is one of the most thorough DIY fridge diagnosis vids I’ve watched. Without a doubt this video will save folks a ton of fridge service charge and replacement cost money 💰🙏🏼🤩
It just saved me lots of money.
You saved another Whirlpool from the trip to the junk yard. Replaced the fancy relay but not the cap. My local appliance parts vendor said this was a commonly replaced part and the cap very rarely needs replacing. My fridg, with it's bottom freezer, also had Very dirty coils mounted across the bottom near the floor. Had to empty it so I could tilt it and properly remove the dust from the coils. Once all sealed up it took awhile for temp to drop because all the food was so warm. So far so good!
Your video is 14.5 minutes long but I haven't watched it for up to 1 minute when I realized I'm watching the right video. This, is the best diagnosis UA-cam video I ever watched. Thanks for taking your time to make this.
I guess you could feel that way if you don’t know shit from shinola about refrigeration like this guy, let’s just hope he doesn’t hurt himself and sticks to his day job !

This video saved me at least $700! This is the best video on the web for sure!
Thank you so much. It’s amazing how you explained the problem in details. It looks as if a professor is explaining the problem in a college class room. Again thank you sir.
This video helped me out a lot. I appreciate the in depth instruction. I can't afford a new fridge/freezer right now and you helped save us the service fee and learn something new in the process :)

Thank you-your explanation and diagnosis is very easy to understand, Good job!
Even though there are many praises for you, I still want to say that you are the best! Clear, easy to understand, and most of all, I fixed my refrigerator.
Thank you!
Thank you Dave, even though my refrigerator freezer is GE, this was the best video I have seen so far, you make so easy to understand! Thanks again!
This is an outstanding video. I"m a DIYer also and this was SO easy to follow. Being curious about circuits, I wanted to see inside that start relay and Dave came through and showed it.
If you understand how a refrigerator (or air conditioner) compressor starts up at each run cycle, it makes more sense that the start capacitor would be bad because that capacitor gives the compressor the extra electrical kick it needs to get it started. Most relays either work or they don't (at all), so I immediately suspected the start capacitor and not the start relay. In this case (and in most newer fridges), the start capacitor is plugged into the start relay and the start relay is then plugged into the compressor, and that means the start capacitor can become electrically disconnected from the compressor if the start relay circuit is damaged. This would prevent the start capacitor from supplying the electrical boost that the compressor needs to start up.
This video convinced me that my nearly new fridge probably needs a new start relay. Mine uses the same type of setup as Dave's does, with the start capacitor plugged into the start relay which is plugged into the compressor - so I'm pretty confident Dave just helped me solve my problem.
Hello Dave, Thank you for your knowledge and clear instruction for troubleshooting, both in easy to understand verbal communication and detailed visual aids! Our Frigidaire refrig/with lower freezer is only 11 years old and still in such wonderful shape that it is hard to think about replacing it, especially when items are so often delayed due to extenuating supply chain circumstances. I'll be working on this now and here's hoping it will be back up and running in no time! Appreciation abounds, sincerely!
Awesome man. My uncle got me a LG fridge when I moved in his apartment and I noticed couple days ago defrosted food and warm fridge and thus here I am. But your checklist and symptom is exactly as I am experiencing right now - the compressor comes on but after a loud click, shuts off. I'm gonna save this video and thoroughly check my switch. Hoping it's that and not yet compressor ! Cheers !
Thank you Dave, I replaced the relay on my GE. Refrigerator & saved having to buy a new one . Much thanks!!!
THANK YOU SO MUCH! EXACTLY WHAT I NEEDED TO KNOW AND I REPLACED THE STARTER RELAY AND ALL IS BACK TO NORMAL
even though i knew you had the fridge unplugged, when you were installing that support wire that locks in the relay/cap to the compressor and suddenly went into fast-forward mode while your hands were in close proximity to all those electrical components (around 12:00 ), i heard a buzzing right away and it still made me jump a little! :) great video, thanks!
Thanks for the video, gave me the insight of what to look for. I'll be attempting a repair and I'll let you know how I make out. Now you have a beer fridge for your garage, that's always a good thing.
Hello Dave, this is a great video! It is greatly appreciated to see someone adding a list of things to check because it makes the diagnosis so much easier. Fix everything until it is unfixable. In Europe the appliances are much better quality and we have to demand that in North America. Thank you!
Thank you for making this video! I was able to fix my fridge within 24 hours!
Dave, I feel your pain. The part I got tickled with is where the fridge showed up in the garage because your wife decided you were getting a new one. DIY guys like us are so underappreciated. I have an old Maytag upright freezer that suddenly decided to get a little warm. This time, I went and bought a new freezer without even diagnosing the problem. But, I'm going to try to fix it and give it to my little sister from another mister or my wife's little sister to make things more clear. Don't get discouraged. Keep up the great work and good luck in the future!!!
Dude, you da man!! a flat box of frozen mussels blocked the air flow over the coils in the freezer side, and it was a block of ice. Made my day. Thanks!! We Dave's rock (especially you).
The best explaination out of 20 previous opinions. I was able to determine it was the relay by testing with the basic meter. I appreciate it.
Hey thank you very much for this video, very well explained and easy to follow, quick and straight to the point. 👍 You gain a new subscriber.
The best refrigerator repair video on UA-cam! 5:38 Mine was rattling and when i opened it, i found a burnt mark with some kind of disintegrated metal bits and pieces.
You saved me buying a new fridge! Thanks so much!
Thank you for this. It was exactly what my fridge was doing and bought the parts of amazon for under $10. It's working again so you saved me the cost of a new fridge.
Hey Dave! I loved the walkthrough. You are a natural teacher, clear and precise. Thanks! I just defrosted the freezer. The evaporator and condenser fans are working and blowing cold air and freezing. However, the cooler isn't really cooling much. Also, I can't hear the condenser buzzing, so as you show, it could be a relay or capacitor problem. Perhaps the condenser is only half working. Great video!
Agreed, great video!
Very good video with information well explained. I've dealt with evaporator dripping water issue (which froze at the bottom of the fridge and my drawer was stuck). This is a new knowledge so I can get well prepared.
I just fixed mine, thanks to your video! Yes, it was the same issue, the compressor start relay. First I removed it, jotted down the #s, did searches, found out they are out of stock, out of production everywhere. But after looking really close at one on Amazon, I noticed it looked exactly the same as mine (the same shapes, same plug shapes, and it was the same brand)..so I bought it (about $78) plugged it in and whammo! I just ordered another one so when and if it breaks again I'll have one. My fridge was made in 2005, so the original lasted 17 years. I did some cleaning in the coils while under there also (they need to be kept free of dust and dirt). I intend to buy a special brush made for fitting in between the coils but for now I just used my compressed air system's blow hose. Mine is a Frigidaire model FRS6R4 EW2, the original part which is now obsolete had these #s on it: 3ARR55C4E2A and is part # 241543958. The new start relay is a Frigidaire part # 241524611 "compressor start relay", it got here in one day Amazon Prime. I used the original capacitor, it fit the new start relay exactly and apparently it was fine. Bottom line: if you have searched the part # for yours everywhere and it can not be found, just search your brand name and "start relay" on Amazon and look at each one, it helps to have your original in your hand for close examination.
Incredible! We don't have a lot of money and I have been searching everywhere to get layman's terms and you nailed it! Thank you, not just from me, but from my family!
Unfortunately, turns out to be the compressor, but glad I learned this!
That is a helpful and informative video. I recently just fixed my Maytag refrigerator which is a 2013 model. it's very similar to your compressor setup. mine ended up being a bad start capacitor. mine was melting on the floor like yours.
One thing I'd like to note when you were doing your continuity test you had your multimeter set wrong, you had it set on the diode test. You just have to select the resistance scale on your meter to check for continuity
Excellent diagnostic and troubleshooting. Excellent repair 👍
331 downvotes must be repairmen that overcharge! Excellent video!
Man I sure appreciate you for this. I thought I was going to have to buy a new fridge. Thanx for saving me some money
Great video! It helped us repair our "backup" frig and saved us a ton.
After so many years you start to love that compressor sound. It's so calming and relaxing!
Compressors have a distinctive tinny sound when there running.
Thanks so much. I was able to fix my refrigerator by myself because of your video. Total out of pocket cost $10 for the part. Appreciate your video.
Hey Dave you have number1 compressor brand on that unit man, I'm 18yrs on fridge repairs I'm busy in such a way that i couldn't even hv time to create my UA-cam channel but today i created my info episode......keep it up bro all the best.
Thanks for this video. You saved my Rs 4K :) The starter relay costed Rs 100 . Thanks again.

Great video! Thanks for your help. Fixed my refrigerator with a $20 part off of Amazon and your excellent instructions!
GREAT JOB ! ! !
5 STAR VIDEO... You explained everything so good, my Daughter could even understand it too.
Mine was the start relay. Had all the same symptoms. Part cost me about 65 and the place I bought it tested my capacitor and it was good. Took less than 10 minutes to take off the old one and put on the new one. 👍
Flawless video. I'll be doing this tomorrow. I think you just saved me $1500! You're a natural and so direct and to the point.Love it when my time isn't wasted. Thank you sir!
Some charged me 120 just work one hour the relay he put doesn't work anymore u think the guy doesn't know everything about it I'll do my self
I'm about to try taking out the relay and capacitor and relay for testing. I just wanted to tell you what a great job you did describing the symptoms and taking us through a checklist! Thank you so much!
FINALLY SOMEONE EXPLAINS HOW TO TEST THE ELECTRICAL COMPONENTS. GREAT VIDEO
Same here, but I wanted to mention, my relay tested fine, but I replaced it on a hunch after testing the capacitor…. Works like a champ! $20. So consider trying a new relay even if the old one tests!
I'm a training appliance repairmen and honestly this video really helped me understand not only how to check voltages on the compressor units, but you actually did what I wish my teacher would've done for me and go down a list of things that could not work, but do in this case. But I haven't been able to see many fridges yet.

Thank you dude, after scrolling for a while, I finally found a video that explains everything perfectly, with explanations as to why you're troubleshooting each part!
Thank you so much you saved me a bundle! One note, my new part took a different wiring harness that was an additional charge. It was easy enough to switch out but just thought I'd pass it along.
Thank you for making this video! I watched a bunch of videos, but almost everyone I watched was about a refrigerator that did not seem to run. Mine problem is exactly as yours was in this video. I'll be ordering my part next! thanks again
D.W. Great analysis & video - my 2021 Frigidaire FFTR2045VB0 would run 9-10 seconds, and then a loud click. Every 3 minutes - same thing happened. The freezer was 41 degrees. I will be taking the relay off tomorrow... I can see where this is going so ... I'll just say THANK YOU now.
Very informative and useful video. I had same problem 2 years ago after a local electricity cut off, after 10. In inspecting , the LG man said replace it with new one the six years old the side by side. We kept it on and forgot about it, after awhile noticed it had started working. Just recently due to massive heat wave, the problem returned. I can not repair it myself but I live in London and happy to pay to replace the relays and / or capacitor. Shado
As per other commentors, Dave, you've done a great job on this video, particularly with editing in the closeup shots. Thank you for taking time to do this. Now I have to see if any of these points apply to the Electrolux here. Both freezer and fridge compartments are too warm even with the temperature setting dials set to max.
Nice job, very thorough diagnosis. Thanks for explaining everything step by step. Great video.
Great video and walk through Dave, mine was dusty coil and frozen "radiator" - Fixing now!
Well done! That was the problem! $20 fix, for my 20 year old model. Here's to 20 more years! Thank you for your efforts!
Thank you Dave that was awesome I eventually had this problem at first I would hear a snapping sound at least 8-10 times a day until this relay failed, I then replaced both the relay and capacitor at the same time since both had to be removed at the same time anyway
Order an extra set. These are “ no longer available” after 8 years. They want you to buy a new unit. All manufacturers do it on GE’s original mandate. If and when they are no longer available, use a 3 n 1 hard start start/run capacitor. Not pretty but they work great. Not expensive either.
Now you have a garage Frig & a New Kitchen Frig.... Everybody is Happy! Me Too! good Video, Thanks!

Was able to fix my refrigerator from this video the checklist was really helpful cost me 50 bucks five stars
Great video, even called a local repair guy *$85 service call to verify that it was not just the capacity (black box), but proably regulator too or even compressor. Ordered both and plugged them in, but didn't initially fix the problem because the plug came off when I pushed it on the compressor. I didn't see the plug come off until I went back to take it off to return it (Amazon returns). The plug was exactly like the original, but did eventually go on with extra force and stayed.
I was about to buy a new fridge until I saw your video, my fridge had the same problem, the compresor will kick on, then turn off, and I would hear the click, I am pretty handy with tools so after seeing your video, now I know what it is!!!! Thank you so much for taking the time to make these video, I feel like I owe you money!!!
Thank you so much for this video. I had the same issue, ordered the start relay and capacitor from Amazon and they worked perfectly. My Frigidaire refrigerator is working beautifully again. Thanks again.
Voltage rating on a capacitor doesn't mean it's giving the compressor a shot of that voltage - it's the maximum voltage it will handle without shorting.
Came to the comments to see this comment. Thank u sir! Capacitors don’t increase voltage they simply hold a charge and are rated for up to a certain voltage
How can to contact U
I have the same "basic" multimeter as in this video and do not understand the logic / explanation on how he validated the capacitor was "good" / "not the issue". Any feedback, please?

Thanks Dave. Your video was the best I have come across and I was able to confirm that my starter relay was bad. We are having a bad freeze here in Houston and keep on loosing power. One of the times the power came back on, the cooling on the fridge stopped. Because of the freeze I just put my food outside. Not ideal but its working and yes.....it's secured from animals.
Same here in Kentucky
Whadda man, good job!
The way you simply explained all the step was amazing because you made it simple to understand. Thank you.

After watching a dozen videos and several Google explanations, this video was the only one that fully explained that both bottom terminals on the start relay should have continuity with starter relay removed. My symptom was no compressor start up but 5.4 amps draw, then relay clicked off. I disassembled mine after finding no continuity. I noticed the disk inside (no electronics board) was burned only on one side. I decided to flip the disc 180° and continuity returned. I reinstalled the starter and capacitor to test compressor power up. It worked fantastic! I will be replacing the starter only as capacitor tested good. Thank you for you thorough explanations.
The capacitor is used to excite the heavy motor into rotation and also suppress any arcing across the relay contacts. The cap’s 250V is merely its maximum rating.
No. It’s not. It’s a run capacitor and has nothing to do with starting that compressor 🤣
I am fairly certain that a Supco "hard start kit" (Part# RCO410) would achieve the exact same results but would cost far less (roughly $12.50).
No. It won’t. Supco 3 in 1s provide ZERO thermal protection for your compressor. They rely on amp draw to pretend to “thermally” protect your compressor and in most appliances, the thermal overload is part of the start relay or is held onto the compressor by the electrical cover for the compressor. Teaching home owners to use them is a disaster waiting to happen. Also, his compressor has a run capacitor, not a start capacitor. 3 in 1s are start capacitor/start relay combos with a half assed overload sized for a range of horsepower compressors.
@@jman0870 With all due respect... 1) You know all of this how? What is your background / credentials? 2) Also (FYI) the supco specs (on their website) states that the part is for "refrigeration systems with or without run capacitors"
@@jotu173 Does it state with or without start capacitors? Why would you install a start capacitor on a low back pressure compressor? Do you like damaging compressor motors? My credentials are I do this for a living.
@@jman0870 Your credentials are pretty vague as a lot of people with almost ZERO actual credentials ( and / or very limited experience) "do it for a living". I'm asking you about specific credentials like 1) How long have you been "doing this" and 2)in what capacity? 3) Do you have an EPA (UNIVERSALLY certified technician) "608 card"? 4) Did you graduate from a trade or vocational school?

You are a god! Lol no, really man. It was more than enough to figure out the diagnosis issues. This video will help repair two items, mini fridge & a defrost issue on my in home fridge. Salute brother.
Good video. Learn to fix your appliances and cars people. You can literally save thousands.
Fun fact - The job of a refrigeration unit is to absorb heat and blow it away. What is left is cooler/colder air. They don't actually 'make' cold air, it's just what happens when excess heat is absorbed and gotten rid of.
It’s why I want to ditch ammonia and hydrogen charged absorption refrigerator and get a compressor driven unit. Absorption units take so long to cool.
That's half way true... As an HVAC tech I can tell you that the refrigerant inside the compressor changes from a liquid to gas state and it does indeed actually make coldness. While it is in a cold gas state, it absorbs the heat and removes it. So the answer is it both makes cold air and take the heat out at the same time.
Well it's even more interesting, when the compressed liquid goes to a gas state, it still doesn't make cold, it just expands. So the same amount of heat energy that was in a small amount of liquid, is now spread out over a much larger volume of gas (which is what drops the temperature - in fact, the amount of heat energy in a volume of stuff is what temperature _is_). Same reason spray on deodorant comes out cold
My ex husband is an HVAC tech. I wish I had a nickel for every time he said something doesn't make cold air it removes heat. Removing heat is how you make cold air. So yes, refrigerators make cold air, air conditioners blow cold air. It's silly to say something doesn't make cold, it removes heat. That's like saying don't turn left, turn away from right.
That's it, when anything flashes from a liquid to a vapor, or a solid to a vapor it absorbs heat. Refrigeration 101.... Compressor compresses the refrigerant into a high pressure gas, condenser turns it to a high pressure liquid, when it reaches the evaporator it passes through a small orifice and flashes to a low pressure liquid/vapor mixture as it passes through the evaporator changing to a low pressure gas/vapor is when it absorbs heat. When the refrigerant Runs through the condenser it blows that heat off. This cycle repeats until the temp control is satisfied then shuts off.
I like the way you put this video together, it's genuine and clear thinking. It was interesting to see the guts of the relay, obviously containing a series of capacitors, diodes, and at least one MOSFET. The days of the simple PTC or current relay are almost gone. I also like the way you searched for the exact replacement part. In the pro world, people won't accept a delay of a couple of weeks to get an exact match, so many carry a so called "3 in 1 hard start kit" on the truck, containing a generic relay, an overload switch, and a capacitor. Those kits are cheaper but are not nearly as reliable or as durable as the OEM version, and they don't necessarily balance the load properly. However by being a general solution, repair guys can get the fridge working within minutes, and if it doesn't work there is no delay. With a quick solution it is easier to resist the pressure to buy another fridge right away, but sometimes the compressor fails a few months later.
Excellent video Sir. Best one I’ve seen lately. Thank you for making it!
