WP4387490 Whirlpool Refrigerator Bimetal Defrost Thermostat
Product Description
The WP4387490 Whirlpool Refrigerator Bimetal Defrost is an essential component that regulates the defrost cycle in your Whirlpool refrigerator. It is located in the freezer compartment and acts as a safety switch by detecting temperature. 1When a predetermined amount of frost accumulates on the evaporator coils, the bimetal defrost system activates. This clever mechanism interrupts the cooling cycle and turns on the defrost heater. The heater then melts any existing frost, preventing a buildup that could impair the refrigerator's performance. When the temperature rises to a safe level, the bimetal defrost resets and the refrigerator resumes its normal cooling operations. The WP4387490 Bimetal Defrost avoids excessive frost buildup, which can impede cooling and waste energy.
