Is This the Part You Need?

Part number WP10442411 is the defrost thermostat (defrost limit switch) for Whirlpool, Kenmore, Amana, and KitchenAid refrigerators. This thermostat monitors evaporator temperature during the defrost cycle and cuts power to the defrost heater once the coils reach the correct temperature. When it fails open, the defrost heater never activates — ice builds up on the evaporator coils, airflow is blocked, and the fridge stops cooling. Left unrepaired, it leads to food spoilage and potential compressor damage.

Symptoms of a Failed Defrost Thermostat

  • Refrigerator not cooling despite compressor running
  • Thick frost or ice buildup on the back wall of the freezer
  • Freezer cold but fridge section warm
  • Evaporator fan running but no cold air circulating
  • Fridge cools temporarily after manually defrosting, then fails again
  • Frost visible on evaporator coils behind the freezer back panel

💡 Pro Tip — Replace the Defrost Heater at the Same Time:
If the thermostat failed because the defrost heater ran too long or overheated, the defrost heater assembly may also be damaged or weakened. While the evaporator panel is already off, test the heater for continuity — replacing both together costs far less than a second disassembly call later.
