Whirlpool WPW10392132 Refrigerator Defrost Thermostat

Description

The Whirlpool WPW10392132 Defrost Thermostat is a genuine OEM bi‑metal safety device used in many Whirlpool‑family refrigerators. Its job is to monitor the evaporator coil temperature and open or close the defrost circuit to prevent overheating during the defrost cycle.

When this thermostat fails, the refrigerator may stop defrosting, leading to frost buildup, warm temperatures, or poor airflow. Replacing it restores proper defrost operation and keeps the evaporator from icing over.
