Ge Temperature Sensor

By: Ge

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.

This part fixes the following symptoms

Fridge too cold
Too warm
Fridge runs too long
Freezer too cold

Ge Defrost Thermostat

5.0 (28)

By: Ge

Part Number: WR50X10065

The Defrost Thermostat is an OEM part for GE refrigerators. This component is essential in regulating the defrost cycle, ensuring that the refrigerator's evaporator coils do not become frosted over, which can impede airflow and cooling efficiency. The thermostat monitors the temperature of the coils and activates the defrost heater when necessary to melt any accumulated frost.

Symptoms of a failing Defrost Thermostat include:

Excessive frost buildup on the evaporator coils
The refrigerator or freezer compartments being too warm
The refrigerator running continuously without cycling off
Water leakage inside the refrigerator due to melting frost
Unusual noises as the compressor overworks to maintain temperature

Causes of a bad defrost thermostat can include normal wear and tear over time, exposure to moisture that can cause electrical issues, or a failure in the internal sensing mechanism that prevents accurate temperature regulation.

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.
