6615JB2005C LG Refrigerator Defrost Thermostat

Refrigerator Defrost Thermostat

The defrost thermostat is a crucial component in refrigerators, specifically designed to detect the rise in evaporator temperature during the defrost cycle. Once all the frost has melted, it turns off the defrost heater.

This part is an OEM component for LG refrigerators and is also compatible with Sears-Kenmore models. It monitors the evaporator coil temperature to prevent frost buildup by signaling the control board to initiate the defrost cycle when needed.

Over time, the defrost sensor assembly may fail due to normal wear and tear, electrical problems, or exposure to moisture and temperature changes. A malfunctioning defrost sensor can result in improper defrost cycles, excessive frost buildup, reduced cooling efficiency, or a complete failure to defrost.

Common signs of a faulty defrost sensor assembly include:

- Excessive frost on the evaporator coils
- Inconsistent refrigerator or freezer temperatures
- Higher energy consumption
- Failure of the refrigerator to defrost properly

This OEM part addresses issues such as frost buildup, failure to shut off, and a refrigerator that is too warm.
