Whirlpool WPW10392132 Refrigerator Defrost Bi-Metal Thermostat
Product Description
The Whirlpool WPW10392132 Refrigerator Defrost Bi-Metal Thermostat is an innocuous but crucial element within your refrigerator, specifically located in the freezer compartment. It monitors temperature changes and functions similarly to a self-regulating switch. The temperature drops as the freezer cools and frost builds up on the evaporator coils. The bi-metal thermostat flips a switch when it hits a pre-set level. By heating the coils, the defrost heater is triggered, melting any accumulated frost. The bi-metal thermostat resets when the temperature reaches a safe level once more, which is usually slightly over freezing. By doing this, the heater is turned off, avoiding needless heating and guaranteeing effective defrost cycles. The W10392132 Bi-Metal Thermostat assists in preserving your refrigerator's ideal temperature control by managing the defrost cycle.
