Doug for Model Number GE Monogram - ZIS420D Replaced Compressor and Inverter 2 yrs ago, compressor will not run, thinking its time to replace the Main Board, how can I tell if the Main Board is bad. Also the Tech Data sheet provided with the fridge states Main Board - WR55X10560 is this correct. Thank You
Answer Hello Doug. You will test for power from the main board to the inverter. If none is there, replace the main board WR55X11130 is the correct one. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
