Temperature Sensor (Thermistor Assembly)
Genuine Ge part
By: Ge
Part Number: WR23X10582

This temperature sensor monitors internal refrigerator temperatures and relays them to the control, helping the unit maintain consistent cooling. Replacing a failed sensor restores accurate temperature regulation and more reliable operation. What it does:

  • Measures compartment or evaporator temperature and sends a resistance signal to the control board
  • Helps the control modulate compressor and fan run times for proper cooling
  • Typical failure signs: sections too warm or too cold, erratic temperatures, or running longer than normal
  • Causes inaccurate temperature readings compared to setpoints
What's included:
  • 1 temperature sensor assembly
Install notes:
  • Disconnect power before servicing
  • Access the sensor in the affected section; release any cover/clip and unplug the connector
  • Route the new sensor's wiring like the original and ensure it's fully seated in its holder or clip
  • Restore power and allow up to 24 hours for temperatures to stabilize
