This 642 has temps around 18f at freezer and 45f + at FFside. The compressor for the freezer runs fine, the compressor for the FF is cold and there is not 120vac at the wires to the relay.
The display says 'Service' and there is a EC on the right of the display where the temp should be for the FF section.
I found the control board test sheet and ran all the test listed, seems I got 120vac at every test that I was supposed to get 120vac.
I couldn't get any other error codes other than EC and service to show up on the display. Are there some test points on the board I can check for the compressor and wouldn't that tell me if its the board, or something else?
Does anyone happen to have the service manuaul?
Thanks in advance.
