WR55X10025 Genuine OEM GE Refrigerator Temperature Sensor
The WR55X10025 is a genuine GE OEM temperature sensor, also called a thermistor, for GE, Hotpoint, and Kenmore refrigerators. This sensor measures air temperature inside the refrigerator or freezer compartment and reports it continuously to the main control board, which uses that reading to regulate the cooling cycle. On some models, this same sensor design also serves as the defrost sensor mounted on the evaporator coil, monitoring temperature there to help manage the defrost cycle.
Because the control board relies entirely on this sensor's reading to make cooling decisions, a failing or inaccurate sensor can cause the refrigerator to run too cold, too warm, or run for excessively long periods as it tries to correct a temperature it's misreading. On models where it doubles as a defrost sensor, a failure here can also contribute to frost or ice buildup in the freezer. This is a relatively inexpensive part, and it's commonly the actual cause behind symptoms that get mistakenly blamed on the main control board. It directly replaces AP3185407, 914093, AH304103, EA304103, PS304103, WR50X10027, WR50X10034, WR50X10055, WR50X10067, WR55X10025B, WR55X10026, WR55X10027, WR55X10028, WR55X10030, WR55X10087, WR55X10088, WR55X10089, WR55X10367, WR55X10380, WR55X10661, WR55X10711, WR55X10735, WR55X10736, WR55X10737, WR55X10937, WR55X10938, WR55X10939, WR55X11121, WR55X11141, WR55X11150, WR55X11151, and WR55X11152.
Quick Answer
The WR55X10025 Genuine OEM GE Refrigerator Temperature Sensor fixes GE, Hotpoint, and Kenmore refrigerators that run too cold, too warm, run for excessively long periods, or (on models where this sensor doubles as a defrost sensor) show frost or ice buildup in the freezer. A healthy sensor reads approximately 5,000 ohms at 77°F. Replaces AP3185407, 914093, AH304103, EA304103, PS304103, and a wide range of WR50X/WR55X-prefix numbers listed below. This is an inexpensive part that's frequently the actual cause behind symptoms mistakenly blamed on the main control board — worth testing or replacing before assuming a costlier board repair is needed.
Common Problems This Part Fixes
- Refrigerator running too cold
- Refrigerator running too warm
- Refrigerator running for excessively long periods
- Freezer not defrosting properly (on models where this sensor also serves as the defrost sensor)
- Freezer too cold or showing frost buildup

Installation Notes
⚠️ Danger — Authorized Service Part Required For Flammable Refrigerant Systems GE's own service guidance carries an explicit warning for this component: it is a manufacturer-authorized service part intended for use in refrigerator models that use a flammable refrigerant, such as R600a. Using an unauthorized or incorrectly rated service part in a unit that uses a flammable refrigerant could lead to a risk of fire or explosion. Before ordering or installing, confirm your refrigerator's refrigerant type and verify this part is correct for your specific model. If you have any doubt about your refrigerant type or the correct part for your unit, contact our support team with your model number before proceeding, or have a qualified appliance technician perform this repair.
⚠️ Unplug Refrigerator Before Starting — Test With A Multimeter Before Replacing Disconnect power at the outlet before beginning, and move perishable food to a cooler for the duration of the repair. Wear work gloves. Before replacing, it's worth testing the old sensor with a multimeter set to ohms — a healthy sensor reads approximately 5,000 ohms at 77°F; a reading well outside that range, or an open circuit, confirms a failed sensor. Locate the sensor, typically mounted on an interior wall of the compartment or clipped to the evaporator coil depending on your model. Photograph the wiring and mounting position before disconnecting anything. Disconnect the sensor's wire connector, remove any mounting clip or bracket, and pull the old sensor free. When positioning the new WR55X10025, make sure it sits in open air away from direct contact with ice buildup areas, since ice touching the sensor can cause it to read colder than the compartment's actual temperature. Reconnect the wire connector and secure the mounting clip. Restore power and monitor the refrigerator over the next 24 hours, comparing the display temperature to an independent thermometer placed in the compartment to confirm accuracy. Tools needed: multimeter, work gloves.
Frequently Asked Questions
How do I test whether this sensor has actually failed?
Use a multimeter set to ohms and test the sensor across its two terminals. A healthy sensor typically reads approximately 5,000 ohms at 77°F room temperature; a reading significantly outside that range, or no reading at all (open circuit), confirms the sensor has failed and should be replaced.
My display shows a temperature that doesn't match how cold the fridge actually feels. Could positioning be the issue, not the sensor itself?
Yes, this is a documented and somewhat subtle failure mode. If the sensor ends up positioned too close to an area where ice or frost accumulates, the ice's surface temperature can pull the sensor's reading colder than the actual compartment air temperature, causing the display to show a colder number than reality — sometimes off by several degrees. One customer traced exactly this issue to ice buildup near the sensor location and resolved it by ensuring the new sensor sat clear of that ice-prone area during installation.
Could my problem actually be the control board instead of this sensor?
It's worth testing this sensor first before assuming a control board issue. This is a relatively inexpensive part, and it's commonly the actual root cause behind symptoms that get misdiagnosed as a control board failure, since the board is only ever as accurate as the temperature data it receives. Testing or simply replacing this sensor is a low-cost step worth taking before pursuing a more expensive board repair.
Why is there a fire/explosion warning on this part?
Some refrigerators use a flammable refrigerant, such as R600a (isobutane), instead of older non-flammable refrigerants. Electrical components near refrigerant lines can be a source of ignition if a leak were ever present, which is why GE requires an authorized, correctly rated service part for these systems rather than a generic substitute. Confirming your model and refrigerant type before ordering is the appropriate precaution.
Is this an OEM or aftermarket part?
This is a genuine OEM part, manufactured by GE to factory specifications — guaranteed fit, materials, and performance. It matches the original resistance curve and mounting configuration of the temperature sensor originally installed in your refrigerator.
