Customer Questions and Answers for Temperature Sensor by Ge

Best Seller
Manufacturer Part
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.

Victor, For this model, check the damper to ensure that it is not stuck open and if it is not then this will most likely be caused by a faulty temperature sensor.

Jula for Model Number GWE19JSLGFSS

Is the temperature sensor in the refrigerator behind the led cover? I have replaced one sensor in the freezer, thermistor, defrost heater, and the evaporator fan assembly. The back panel has not frozen over again yet, the fan is spinning, the freezer is freezing but the refrigerator is still warmish. The temperature sensor in the refrigerator seems the last thing but trying to locate. Also how to remove the LED light cover if the temperature sensor is behind it? Thx

1 Answer

Hello Jula, The fresh food temperature sensor WR55X10025 is in the light housing. Take a small screwdriver and pry the light lens off from the rear. It is apparent from there how to remove it. Remove the screws and drop the housing down to access.

Deby, There is a defrost sensor on the evaporator coil of the freezer. If this has also been replaced then the issue will be the control board of the unit which is part number WR55X10942C.

Thomas, thanks for the question. It is normal that the temperature can vary by a degree or even a few at any point during the operation of the refrigerator. It is the long run time that may be of concern. It could indicate a leak in the sealed system or an improper freon charge. If both of those are checked and appear ok, I would not be too concerned as 134a is not the most stable of freons and can vary from charge to charge.

Thao, there will be one evaporator thermistor WR55X10025 located on the top of the evaporator, one freezer thermistor WR55X10025 located on the right side wall behind a grille cover WR02X10647, and one refrigerator thermistor WR55X10025 located on the right side wall behind another grille cover. When replacing the damper assembly WR49X10251, the duct transition WR02X13091 may need to be replaced if it has become deformed or damaged.

Michele for Model Number PWE23KSKBSS

Freezer compartment temperatures are all over the place (typical range when set at 0 is 17-40 degrees. Had GE techs come out 3 times, first time they told me the door was being left open (it wasn’t), then they switched out the main board (didn’t help) and last they told me they thought it was faulty door switches (the computer was telling them the doors had open/closed 600 times in 8 days- clearly wrong). Door switches all replaced and still not coming back into normal tempuratures. We just replaced the temp sensor in the back of the freezer compartment, thinking that might help- nothing. Could they have installed a bad board? Is it more likely a sealed system issue (valve stuck)? They are coming out for a 4th time and I’d like to have some intelligent questions and requests to ask. This unit is only 3.5 years old- it would kill me to have to replace it already.

1 Answer

Michele, For a freezer compartment that is fluctuating between 17 and 40 and not going any lower sounds likely that there may be a sealed system issue. Possible restriction of the lines but would suggest checking to see what the coils in the freezer look like. A frost pattern where there is just a partial frost pattern would be a sealed system.

Vivian, Look for an oval grill on the ceiling or sidewall and the sensor will be located under this grill.

Dave for Model Number ZICP360SRASS

Help,,, After completing the following and checking connections twice my freezer still ices up and refrigerator gets warm: Replaced temperature sensor on evap. coil Replaced defrost heater Replaced Evap. Thermodisc Replaced thermostat Replaced fan motor Replaced Main control board Replaced Inverter Board. I only replaced (1) temperature sensor on the evap coil. Did I miss one? Looks like there is one for the ice maker and one for the refrigerator. Help.....

1 Answer

Dave, there is one thermistor WR55X10025 for the freezer cabin (located near the ice maker), and two thermistors WR55X10025 in the refrigerator section (located behind the left snack drawer). It would be recommended that these thermistors are tested for resistance to identify if there are any that are not operating properly. This can be done from the main control at connection J1. With the refrigerator unplugged and a thermometer in the refrigerator and freezer sections, one probe will go on the brown wire at connection J1 pin 5 and stay there. The other probe would go to the purple wire to test the left refrigerator thermistor, the blue wire for the right refrigerator thermistor, and the red wire for the freezer thermistor.
