XPARTCO WR55X10025 Refrigerator Temperature Sensor
The XPARTCO WR55X10025 is an aftermarket replacement refrigerator temperature sensor (thermistor) compatible with a wide range of GE, Hotpoint, Haier, Café, and Monogram refrigerators. The temperature sensor monitors air temperature inside the fresh food and freezer compartments and sends that data to the main control board, which uses it to regulate cooling cycles and maintain the correct set temperature. When the sensor fails, the refrigerator may run too warm, too cold, or experience erratic defrost behavior.
This sensor measures approximately 1-1/4 inches long and includes 18-inch wire leads. It is constructed from white plastic and is used in both fresh food and freezer compartments depending on the model — on some models it also functions as a defrost sensor on the evaporator coil. It directly replaces OEM part numbers WR55X10025 and a large number of earlier GE thermistor part numbers. Sold individually — some models require two sensors. Installs in under 30 minutes with basic hand tools.
Quick Answer
The XPARTCO WR55X10025 Refrigerator Temperature Sensor fixes GE and Hotpoint refrigerators that are too warm, too cold, not defrosting, or over-defrosting. The thermistor monitors compartment temperature and communicates with the control board. Approx. 1-1/4" long with 18" leads, white plastic. Compatible with GE, Hotpoint, Haier, Café, and Monogram refrigerators. Sold individually.
Common Problems This Part Fixes
Refrigerator compartment running too warm — food spoiling faster than normal
Refrigerator running too cold — food or liquids freezing in the fresh food section
Freezer section not maintaining correct temperature
Refrigerator not defrosting or defrosting too frequently
Excessive frost or ice buildup on evaporator coils
Refrigerator and freezer both warming up after extended defrost cycles
Erratic cooling — temperatures fluctuating unpredictably

Installation Notes
⚠️ Unplug Refrigerator Before Starting Unplug the refrigerator from the power outlet before beginning any repair. To access the fresh food thermistor, locate the sensor on the left wall of the fresh food compartment — it may be clipped into a housing or bracket. Disconnect the wire connector and pull the old sensor out of its bracket. Slide the new WR55X10025 sensor into the bracket and reconnect the wire connector. To access the freezer or evaporator thermistor, remove the freezer shelves and back panel, then locate the sensor clipped to the evaporator coil bracket. Remove any tie wrap securing the sensor, pull the old sensor from the bracket, insert the new sensor, and reconnect the wire connector. Reinstall the back panel and shelves, restore power, and verify the refrigerator returns to the correct set temperature. Tools needed: Phillips screwdriver, flat pry tool (for panel clips), work gloves.
Frequently Asked Questions
How many temperature sensors does my GE refrigerator have?
The number of sensors varies by model. Many GE French door and side-by-side refrigerators use two or three WR55X10025 sensors — one in the fresh food compartment, one in the freezer, and sometimes one on the evaporator coil. Check your model's parts diagram or contact our support team with your model number to confirm how many you need before ordering.
What is a thermistor and how does it work?
A thermistor is a type of resistor whose electrical resistance changes with temperature. The main control board sends a small voltage through the thermistor and measures the resistance — a higher resistance means a lower temperature, and a lower resistance means a higher temperature. The board uses this reading to decide when to run the compressor and fans to maintain the set temperature. A failed thermistor sends incorrect readings, causing the refrigerator to over-cool, under-cool, or malfunction during defrost cycles.
Can a faulty temperature sensor cause the refrigerator to not defrost?
Yes. On models where the WR55X10025 also serves as the defrost sensor on the evaporator coil, a faulty sensor can cause the control board to incorrectly time or skip defrost cycles entirely — leading to excessive frost or ice buildup on the evaporator coils. This frost buildup can eventually block airflow and cause both the refrigerator and freezer sections to warm up.
How do I know if my temperature sensor is the cause of my cooling problem?
The most reliable way to test the thermistor is with a multimeter. Disconnect the sensor and measure its resistance at room temperature — a working WR55X10025 should read approximately 16,000 ohms at 32°F, dropping as temperature increases. An open circuit (infinite resistance) or short circuit (zero resistance) reading confirms the sensor has failed. If resistance is within the normal range but the refrigerator still has issues, the control board or other components may be at fault.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine GE OEM part, but is manufactured from durable plastic to match the dimensions and performance specifications of the original WR55X10025 temperature sensor.
