Whirlpool R0131577 Refrigerator Defrost Timer
Product Description
The Whirlpool R0131577 Refrigerator Defrost Timer is a necessary replacement part made exclusively for Whirlpool refrigerators. It's the unsung hero who keeps your refrigerator running smoothly and your food fresh. This timer controls the automatic defrost cycle, which avoids frost development on the evaporator coils. Normally, during operation, moisture from the air condenses on the cool evaporator coils, resulting in frost. The defrost timer triggers a periodic heating cycle for the compressor to exert more effort, hence reducing its longevity that melts the frost, keeping it from collecting excessively. Thick frost insulates the coils, limiting their ability to absorb heat from the refrigerator compartment. This causes the compressor to work harder, ultimately shortening its lifespan.
