Question

Quizplus · Accepted Answer

The defrost cycle in a domestic refrigerator that depends on the run time of the compressor is typically started by a defrost timer. This timer is typically set to activate the defrost cycle at regular intervals, such as every 6, 8, or 12 hours, depending on the specific model of the refrigerator. When the timer reaches its set point, it initiates a defrost cycle by turning off the compressor and turning on the defrost heater or heaters. This allows ice and frost to melt from the evaporator coils, which is then drained away by a drip pan or tube. Once the defrost cycle is complete, the timer will turn off the defrost heaters and turn the compressor back on, resuming normal cooling operations.
