Thermostat (Fixed, Thermal Cut-Off)
Genuine Whirlpool part
By: Whirlpool
Part Number: WP4375079

This fixed thermostat protects the appliance by opening the circuit when excessive heat is detected. Replacing a failed or weak thermostat restores reliable over-temperature protection and helps prevent heat-related shutdowns.

  • Helps maintain safe operating temperatures around heat-sensitive parts
What's included: 1 fixed thermostat Installation notes:
  • Disconnect power before servicing; some appliances contain high-voltage components
  • Access location varies by model; note wire positions before removal and transfer one lead at a time
  • Reuse existing mounting hardware; ensure firm terminal connections and correct orientation
  • After replacement, confirm proper airflow/venting and normal operation
