Customer Questions and Answers for Temperature Sensor (Thermistor Assembly) by Ge

Steve, The best option would be to purchase a multi meter TJMA-DM1 and test the resistances and circuitry of the heater, thermostat, and sensor. it will be less expensive in the long run, and you'll have a "tool" to use around the house or car, etc. You'll also want to check a couple of other things once you're inside the evaporator cover. After you have determined what component you need, also check to make sure the WR51X10105 defrost drain clip is attached to the bottom of the heater and is positioned in the defrost drain opening, and check to make sure the drain tube inside the wall isn't clogged with debris( hot water and a turkey baster works pretty well just be ready to clean up the water). Then check and make sure all the door gaskets are sealing against the front flange of the openings, especially along the bottom of the doors.
