Customer Questions and Answers for Board Assy, Main Control by Ge

Imagerep, if the temperature sensors matched up to what the display was showing, the first step would be identifying if there were any bags or items blocking up the return vent between the fresh food and freezer sides. If clear, the freezer and evaporator thermistors WR55X10025 would need to be tested. With power supply to the appliance turned off, the thermistors would be tested from the main control WR55X11130 at connection J1. The freezer thermistor would be tested from the wire at pin 5 to the wire at pin 3. The evaporator thermistor would be tested from the wire at pin 5 to the wire at pin 4. At -4°F, the resistance should measure 48.4K Ohms and at -13°F resistance should measure 65K Ohms. If the sensors do not measure somewhere in that range, the thermistor has failed.
