R0131577 - Whirlpool Refrigerator Timer

This Whirlpool Refrigerator Timer (R0131577) is a genuine part designed specifically for Whirlpool, KitchenAid, and Amana refrigerators. It's also known as a "Defrost Timer," an essential component in managing your refrigerator's automatic defrost system. The automatic defrost timer operates by switching power to heaters and fans in a programmed sequence to periodically melt accumulated ice. This motor-driven, spring-wound mechanical timer advances cams to open and close electrical contacts at fixed intervals and durations, thereby energizing the defrost heater and terminator. Failure of this timer to advance stops automatic defrost cycles, which can lead to excessive frost build-up. Symptoms indicating the timer may be failing include the refrigerator not defrosting properly or the accumulation of too much frost in the freezer compartment.

Constructed from a mix of metal, wiring, and plastic, this part is located in the machine compartment's condenser, through the timer bracket. Replacing a broken or malfunctioning timer is crucial for maintaining the precise control over the defrost cycle, ensuring efficient, automatic evaporation of frost. Before purchasing, be sure to verify your device's model number for compatibility.
