Defrost timer fridge 25mar18b

A refrigerator defrost timer is a device that controls the defrost cycle of a refrigerator. It is typically located in the control panel of the refrigerator and works by turning the compressor off and activating a heating element to melt any ice that has formed on the evaporator coils. The defrost timer is usually set to run for a certain amount of time, typically every 6 to 12 hours, depending on the refrigerator model. When the defrost timer reaches its set time, it will turn off the compressor and turn on the defrost heater. This allows the ice on the evaporator coils to melt, which prevents the coils from becoming blocked with ice and ensures that the refrigerator can cool properly. Once the defrost cycle is complete, the defrost timer will turn off the defrost heater and turn the compressor back on, returning the refrigerator to its normal cooling cycle. If the defrost timer fails to function properly, it can cause problems with the cooling system and may require replacement by a qualified technician.
