Fridge and freezer not cooling properly. It will get cold initially then compressor will shut down. Seems to work again when I open door then shut again, but it cools intermittently and not sure what causes it to work vs not work. Replaced main PCB, all thermistors were checked and read right ohms at room temp. Compressor seems to work, but feels hot when running. Compressor reads 10.5 ohms.
Any help?

Is the condenser fan motor running? It mounts next to the compressor.

Condenser fan runs when compressor runs. Both evap fans also operating fine. However Compressor seems to “power down” intermittently and doesn’t power back up. It is a variable speed compressor so I’m assuming something is telling it to power down and isn’t getting the speed up signal again.
