How To Test Refrigerator Compressor
START RELAY / OVERLOAD
(Compressor clicking won’t start)
The start relay can also cause the fresh food and the freezer sections not to work. If the start relay is bad, the compressor will not start and you will hear a clicking noise in 2-5 minute intervals. The clicking noise is the overload cutting the compressor off when it overheats from trying to start with a bad start relay. To find out if this is bad first unplug the refrigerator. Then take the cover off that is on the side of the compressor. Now you should be able to see the start relay plugged on to the side of the compressor and unplug it. Now the best way to tell if it’s bad is to shake it. If it rattles, it’s bad and needs to be replaced. If not, most of the time it’s ok. But rather than saying the compressors bad, you might want to replace it anyways because it doesn’t cost much.

the second you take it off ..is the precise moment the camera moves just enough to no show how to actually take it off.
nice
I have checked the current using tester but there is no current
is there current in relay switch in my compressor there is not current coming to relay
I removed my starter and it made a rattling noise when I shook it. I replaced it and it didn’t work. So I took off the overload and that also rattled when I shook it. However, I’ve purchased about 3 overload replacements and they all rattled as well. Is it normal for the overload relay to rattle? Either way, after changing the starter and the overload relays, the mini fridge still doesn’t work.
I’ve done this and it still doesn’t start. Does that mean compressor is bad?
Hey Hey Hey you didnt put the part number in your more info like you said you would of the one you bought. I don't want to pay 44$ on F amazon, I f hate amazon, shit is always more expensive there. and i dont see one on ebay. There has to be a cheaper option…I will prob have it fixed by the time you reply haha
If you test it, you don't need to scape the paint. Just touch the copper process tube. the terminals on the compressor are Common (where the overload is connected) Start and Run. When testing for an internal short, test all three terminals, a short can exist in any of the windings.
We call them "Peanut relays".
While in HVAC/r school we practiced on a lot on donated refrigerators from Kelvinator. They also authored many learning articles. Just remembered them to be bulletproof that used quality parts like Tecumseh USA compressors. So after school when the family needed a refrigerator we bought a no frills Kelvinator. That was 25years ago! Not a single hiccup. Not even sure if this company is still around.
I will try this. Freezer left open, defrosted everything..turns on but no noise…
Do you have exact wiring diagram ?. I have tree wires going in relay (Black, White, Grey) and two wire going in Overload (Black and Blue). How do I retrofit these wires in new Overload/relay which has only two wire ?
sir i nee ur help..
ur WhatsApp number
Sheese $40 for the parts when you could have spent $12 for a capacitive start kit and achieved the same thing..
Also continuity tests do not determine if a compressor has gone bad, You could have a locked rotor, thats why you put a clamp amp meter on it and see what the compressor draws while starting.
samsung single relay and overload kitna price hoga ? kharb he fridge ka
Those technical guys so crazy, they always wanted to replace a new compressor or new refrigerator, but this start relay is cost only $10-$20.
Why dont ur camera stands still nd show what is going exectly….????
As a refrigeration tech, explaining taking covers off and talking someone through a service call or repair, or for those who are a diy kind of person, turning the power off before should be explained before… Some people get in a hurry, or just don't think about turning the power off because they just don't realize how bad it can hurt them if its not off before diagnosing a bad compressor.
Can I use a 250vac-15mf in a 180vac-12mf refrigerator start relay?
man i have the same relay as yours but its only one prong thats connected to a wire is that ok? im still new to this and im tryin to fix by myself
If I have to connect three wires to two black wires on a hard start what should I do
Bahasa Indonesia dong
This appears to be my issue, however my problem is I have a sub-zero mini fridge and can't find a replacememt anywhere on line or in appliance stores. any tips?
Great video man! Thank you so much. Suscribe
I wanted to add my two cents since I appreciate this posting because it has helped me save my fridge and I have done a lot of research since then. The first thing you should do is a continuity check on the three compressor terminals to see if any of the leads are shorted together. If they are then you need to replace the compressor since the transformer windings are shorted. If the compressor is ok then it’s likely the Overload Heat Protect part which is failing likely because there’s a design flaw with the part. I was able to remove mine then reinsert it to get the freezer to work again though it didn’t work well (compressor kept turning on and off and when I replaced it the compressor is staying on). But it gave me enough time to order a new part. The part sells for less than $9 on ebay. Do a search for these part numbers since they will all work for the 110V part: 6750C, 4387913, 2154759, 4357207, 4387766, 4387836, ER4387913, AP3108669, PS371538, SZ4387766, 77600, 586521, AH371538, EA371538. The 220V part is cheaper (has the terminal in the center vs off to one side like the 110V part). Now the 220V part is cheaper (less than $1 each from China) and may work but I was concerned that it could draw less current than the 110V part needs but it could still work so you might want to try it. Do a search for this part number on ebay: R600A. If the Overload part isn’t the issue then do a search for QP2-4.7 3 pin or 4 pin and they sell for under $4. In addition I was able to get the manufacturer to send me the two parts since the freezer was still under warranty (it was either that or ship the freezer out which would be a huge shipping fee). Happy hunting!
Update on this. My freezer stopped working 1 week after I replaced the Overload Heat Protect part so I replaced the QP2-4.7 3pin Start Relay and it’s been weeks and it’s going strong. I also re-installed my old Overload Heat Protect part that I could shake and it made the shaking noise and it works fine. The diagnoses that a shaky Overload Heat Protect part shows you the part is bad is dead wrong. It’s the Start Relay that was replaced which is defective and they are really cheap to buy (likely why they fail so often!). I actually still had the freezer under warranty but they said I had to ship the freezer to Canada at my expense. I asked them to just send me those to parts and I am still waiting for the parts…………..waiting………
Hi,
my GE side by side fridge the compressor is not turning ON I don't hear NO clicks from the motherboard
Thanks… worked for me…
Compressor not stop work continually
