Bimetal Temperature Switch Defrosting Thermostat Customized Home Appliance Parts

Short Description:

Introduction：Defrosting Thermostat Fuse

A defrost thermostat is the temperature-controlling device within the automatic defrost system of a refrigerator. There are three components to the defrost system: a timer, a thermostat, and a heater. When the coils within a refrigerator become too cold, the defrost timer cues the heater to click on and work to melt any excess ice buildup. The function of the thermostat is to prompt the heater to turn off when the coils return to the correct temperature.

How Do Defrost Bimetal Thermostats Work

A defrost bimetal thermostat works separately from the refrigerator or freezer. This device, which turns on several times a day, senses the temperature of cooling coils. When these evaporator coils become so cold that frost starts to build up, the defrost bimetal thermostat facilitates the melting away of any frost that has formed on the cooling coil. The defrost bimetal thermostat does this by activating a hot gas valve or an electrical heating element that raises the temperature near the evaporator, which then melts the frost that has formed.

The melting away of frost buildup protects your refrigerator and freezer's evaporators from overheating during the defrost cycle. The bimetal thermostat and defrost heater work in tandem. When the frost is all melted, the bimetal thermostat will sense the temperature increase and trigger the defrost heater to turn off.
