Customer Questions and Answers for Refrigerator Control Board And Harness Assembly by Ge

Hello Wayne,

The first thing to check is to see if you have frost building on the back wall of freezer compartment. If you have frost build on the wall or impacted coils (with frost) behind the walls then you have a defrost failure. You will need to do a continuity check on the defrost thermostat WR50X10068 and defrost heater WR51X10055. If either does not continuity then that part needs to be replaced. If both check good then you would want to replace the evaporator thermistor WR55X10025 and control board WR55X10942C. 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
