I am trying to fix a GE refrigerator model number GSS22IFPHCC. The compressor is not receiving any voltage when I plug it in only the inner lights come on. I changed the evaporator thermistor because it was out of range. I also changed the temperature control ($$$ dollar expense so far) but still it would not work, only the inner lights come on, but none of the fans work not even the compressor. Could the mother board - also called "main control board" - be the problem? It is located on the bottom back of the refrigerator. Can anybody tell me how to troubleshoot the mother board to be certain that it is bad or any other solution? Thank you in advance for your assistance.
