LG fridge compressor not starting

[unimatrix93]

I disassembled the froster to get to the temperature sensor and fuse.
Turns out both of them are good.
I decided to re check the main power board.
Turns out I made a soldering mistake at the heaters relay,(I replaced all of the relays to new ones) one of the coils leg were not soldered properly.
So I resoldered it and reassembled it into the fridge and the error is gone. The compressor is working and the fridge is cooling too. I wait until monday to test it before I completely reassemble it.

And I will return with the reports.
Thank you all and wish me luck please!

Bad soldering trace joints will get you every time what is that relay powering the hole circuit for the compressor or just part of it

or was it just for the heater for defrost circuit that would explain the defrost error message that you were getting

Do not run the refrigerator very long if you have the panel for the evaporator coil off because you could damage the compressor if you were to run it that way for a long time

Make sure that the controller board is functioning correctly and you do not have any other issues like the display not coming on correctly or not going into defrost every so often it might be every 6 or 8 hours depending on how it is programmed
