LG fridge lmxc23796d/00 not cooling, tried it all

[makocze]

So, all of sudden my 5year LG fridge stopped cooling in both parts. Like many went to YouTube and seems now foolishly believed that doing second test from switchboard, '22' means error or relay so I bought part and replaced it. Result, still not cooling. So I found this forum and one old thread where Vance R explains things more clearly and took steps but reached dead end. Run first 3 minutes test, no error issue whatsoever on the display, besides changing air filter and water filter, and air was blowing through fans inside in both parts with no issue, second time pressing, 22 22 on the door, third time, nothing as it's defrost and was switched off for week waiting for part. So why the air inside doesn't blow and cool it down? Fridge was on whole night with new relay didn't get colder at all (though relay probably wasn't problem).

my observations:

- compressor is vibrating,

- fan inside at the bottom of fridge is spinning

- cleaned coils too

- fridge is empty and cleaned, doesn't seem to have lock issue as alarm would go off

- cleaned inside to make sure there is no ice on coils and inside fan

- when in first test mode, fans inside are blowing and cooling fine so what the pickle?

- nothing blinking on the motherboard

- walls are not moist inside and outside walls seems cooling when plugged in but inside not cold, no air circulation

- this model doesn't seem to have the relay overload protector near compressor just harness (attaching picture), may be it's somewhere else but can't find it

- nothing uneventful happened for it to stop, though may be door closed in smashing manner where I was pulling the turkey out

 

I would appreciate any input and ideas that can point me to the right direction. Been without fridge for Xmas and now New year which is depressing as whole situation is starting to look like my love life, everything seems to be fine but nothing is working so, cheers to all and best for upcoming year

Will take the statement "cooling fine" as the compressor is running with no cooling. 

Most likely a sealed system issue with a inefficient compressor at the top of the list. The next 2 most likely possibilities are a leak or restriction.

May want to check the warranty on the sealed system.

I was hoping may be it's just a $10 temperature sensor inside  Thank you. Just noticed fridge is 3years old may be something can be done without cutting arm and leg. All the best

There's a good chance that an only 3 year old LG has a full parts and labor warranty on the sealed system.  It's highly probable that the compressor is bad, (internal valve problem - the linear compressors are well know for this).
