Whirlpool WP627985 Refrigerator Bimetal Defrost Thermostat
Product Description
The Whirlpool WP627985 Refrigerator Bimetal Defrost Thermostat is an important component of your refrigerator's frost management system. It functions as a little temperature switch. The bimetal defrost thermostat detects rising temperatures inside the freezer compartment. As ice accumulates on the evaporator coils, the ambient temperature rises. When it reaches a certain level, the bimetal defrost thermostat activates. This causes the defrost heater to switch on, melting the collected ice. The bimetal defrost thermostat resets when the temperature falls below the predetermined level, shutting off the heater and allowing the evaporator coils to return to their typical iced state.. This cycle maintains efficient operation by minimising excessive frost accumulation, which can obstruct airflow and impair cooling capacity.
