Customer Questions and Answers for Temperature Sensor by Ge

4.89 (64)
By: Ge
Part Number: OEM9556230
Manufacturer Part Number: WR55X10025

The Temperature Sensor is an OEM replacement part for GE refrigerators, designed to accurately monitor and relay the temperature inside the refrigerator and freezer compartments to the electronic control board. By detecting the slightest changes in internal temperature, the sensor allows the control board to make real-time adjustments to the cooling system, activating the compressor and fans as needed to maintain optimal conditions for food preservation.

Over time, the temperature sensor can fail due to electrical issues, exposure to moisture, or general wear and tear. A malfunctioning sensor can lead to improper temperature regulation, affecting the efficiency of the refrigerator and the freshness of stored food.

Symptoms of a bad Temperature Sensor include:

  • The refrigerator or freezer not maintaining the set temperature 
  • The appliance running continuously or more frequently than normal
  • Inaccurate temperature readings displayed  

This OEM GE part can also be used on Hotpoint, RCA, and Kenmore/Sears appliances.

Tracy for Model Number GSS25GSHECSS

Bought used GE fridge off marketplace for my garage. Freezer display is set at 0 but display reaches 6. Refrigerator is set to 34 but display won’t go below 49-50. Not sure what the problem could be. Is it the temperature sensor, or some kind of fan? When I open the fridge and step on the light to simulate the door is shut I expected the fan to come on thinking the door was shut but I don’t hear the fan on in the fridge. But I don’t know where I should be looking for that? What do you suggest?

Answer

Hello Tracy and thank you for your question. It would be recommended that the temperature inside of the refrigerator and the freezer be verified using a thermometer. This can help identify if the failure is a communication issue where the displayed temperature is wrong, or if it is a cooling failure due to a failed thermistor WR55X10025 or control WR55X40445.
