Refrigerator Thermostats and Temperature Sensors

Keep your refrigerator and freezer at the right temperature with replacement thermostats and sensors for Whirlpool, Maytag, KitchenAid, GE, Hotpoint, Frigidaire, Electrolux and Kenmore models. These parts monitor cabinet and evaporator temperature so the cooling and defrost systems respond correctly.

Parts in This Category

  • Cold controls and temperature control thermostats turn the compressor on and off based on the dial setting.
  • Defrost thermostats and defrost limit thermostats close when the evaporator is cold and open once frost melts, protecting against overheating.
  • Thermistors and temperature sensors send resistance readings to the electronic control board.

Common Signs of a Failed Thermostat or Sensor

  • Refrigerator too warm or freezing food
  • Frost or ice buildup on the evaporator coils
  • Compressor running constantly or not starting
  • Error codes on the display

Choose the Right Replacement

Match your appliance model number and original part number, such as WR50X10068 or WP2321800. Also check temperature rating, connector style and mounting location, because similar looking sensors can have different resistance specifications. Each listing includes cross-reference numbers to help confirm fit.
