Whirlpool WP68233-3 Refrigerator Defrost Timer

The Whirlpool WP68233-3 Refrigerator Defrost Timer is a vital accessory for controlling your Whirlpool refrigerator's automatic defrost cycle. This cycle periodically shuts off the compressor and engages heating parts to melt frost buildup in the freezer section. If left unchecked, frost buildup may hinder airflow, restrict efficiency, and possibly damage the cooling system. The defrost timer is a mechanical device with a revolve cam that completes a cycle over an agreed-upon period, typically around 10 hours and 21 minutes for this kind of device. During the defrost cycle, the timer triggers defrost heaters, which melt the accumulated ice. When the defrost period concludes, the timer switches the compressor back on, resuming normal cooling.
