Ge Temperature Sensor Assembly (Thermistor)

By: Ge

Part Number: WR23X10621

This temperature sensor assembly reads internal refrigerator temperature and sends the signal to the control board so the appliance maintains proper cooling. Replacing a failed sensor restores accurate temperature monitoring and consistent operation. What it does:

Monitors fresh food/freezer compartment temperature and reports readings to the control board.
Helps the fridge cycle the compressor and fans correctly based on actual temperatures.
Common symptoms of a failing sensor: inconsistent temperatures, food spoiling, compressor running more than normal, or erratic cooling.
Works with the control system to support ice maker and defrost control when applicable.

What's included:

One temperature sensor assembly

Install notes:

Always unplug the appliance before servicing to avoid electrical shock.
Handle the sensor and wiring gently; avoid pulling on wires or bending the probe excessively.
Verify connector orientation and secure routing to prevent pinching from the door or shelves.
Test the sensor and control board connections with a multimeter per OEM instructions.

Helps ensure the ice maker fill valve can deliver water into the ice mold
Common symptom: ice maker not filling or making reduced amounts of ice after a freeze-up
Works as a targeted repair when the fill tube freezes but the valve and icemaker otherwise operate

What's included: One fill tube heater (10W) Install notes:

Disconnect power and shut off the water supply before starting any repair
Follow OEM service manual for routing and mounting to avoid contact with sharp edges or moving parts
Verify electrical connections and continuity per manufacturer procedures before reassembly
