Suddenly my 6 year old LG refrigerator quit cooling in all compartments and ruined all my food. I did a lot of troubleshooting with the repair manual and am usually adept at appliance repair, but this has me stumped. So far, I have done the folllowing:
Any help would be appreciated.
- Checked for errors on the display and there aren't any
- Put it in test mode (using the button on the main PCB)
- Checked all the fans are running (the freezer and refrigerator sections are blowing room temp air)
- Condenser fan is running fine
- Compressor seems to kick on and makes about the same humming noise as always. I don't hear any hollow sound, clicking, etc. Since it is a Linear Inverter (ugh!) compressor I Ohmed out the single phase and it was 9.4 Ohms (this is within the specs in the manual). I checked also for shorts to ground and the compressor seems fine. It is a little warm, but not hot. The little copper tube coming off the side of the compressor stays cool though so that may be a bad sign according to some things I have read online.
- I don't see any signs of arc marks on the main PCB and all voltages seem to be there (165 volts on the pins going to the compressor).
Any help would be appreciated.
