I made a service call yesterday on this GE SXS refrigerator.
According to the customer, my visit makes the tenth
time that someone has worked on this frig in the last 12 months.
According to the customer, the frig will go into a deep freeze mode
followed by a strong defrost mode that will thaw the freezer and warm up the frig section. The other techs have replaced the main control board, the temp control board, the heating element, the defrost terminator,the freezer thermiostor.
When I examined the unit, I found a wire on J2 of the main board that had been cut. This wire is supposed to be for the fresh food (FF) section. I believe that the main PCB is not receiving the signal from the FF thermistor so it try to cool more, resulting in the system over-freezing and then going into an extended defrost cycle.
Any thoughts would be appreciated.
