Compressor not running. Check power going to it and nothing. Tested ohms on the compressor. 8-10 ohms approx
Lights and display all working normal so I assumed the main board was ok
Replaced the inverter board. Confirmed there was 4-5bdc on the red and white trigger plug on the inverter. It’s a waveform that is there also but having voltage on the red and white wire of the inverter is a good sign the mother board is ok.
I wanted to confirm the damper door was working properly. The damper is located on the top right side of the freezer compartment and it’s harder to confirm it’s functioning from the refer or food compartment side.
Tested the 2 temp sensors and replaced anyway as a precaution.
You have to cut out and re soldier them back in a shrink tub the connection for a clean install. You can use gray twist caps if you don’t have soldier.
I replaced the main board as a preventative maintenance.
