Brian for Model Number GDL22KCWASS I recently had to manually defrost my condenser in my bottom freezer. A layer of ice had built up blocking air from reaching the refrigerator. Ever since, the refrigerator seems to be constantly running. I suspect the thermal sensors have gone haywire, but I'm not sure how or which one. My J1 plug on the circuit board has white wires on pins 1, 3 and 4. Brown wires on 5 and 9. Assuming the common wire is in pin 5, I'm getting readings at pin 1 of 7.4k ohms , pin 3 at 10k ohms and pin 4 at 4.2k ohms. Fridge temp is 35 and freezer at -10. What are the chances both sensors went bad?
Answer Brian, pin 4 is for the evaporator thermistor, pin 3 is for the freezer thermistor, and pin 1 is the refrigerator thermistor. Based on the resistance readings they have all failed as the RF sensor is registering 59°, the FZ thermistor is registering 50°, and the evap sensor is registering 83°. You will want to verify the temperature of the cabins with a thermometer to ensure that there is not a control issue. The sensors are all part number WR55X10025. Read More...
