Whirlpool WP3-81329 Refrigerator Defrost Timer
Product Description
The Whirlpool WP3-81329 Refrigerator Defrost Timer is an important component that controls your Whirlpool fridge's automatic defrost cycle. This timer regulates the changeover between cooling and defrosting cycles. The compressor is turned on and off by the timer to maintain the refrigerator's temperature during regular use. The timer starts a defrost period when it reaches a predetermined point in its cycle. This melts any frost accumulation on the evaporator coils by turning off the compressor momentarily and turning on the defrost heater. Once the defrost period is finished, the timer returns the refrigerator to cooling mode. A correctly operating defrost timer keeps your refrigerator running efficiently by eliminating excessive frost formation, which can impair chilling effectiveness and increase energy consumption.
