Refrigerator Bi-Metal Defrost Thermostat

The Defrost Thermostat is an original equipment manufacturer (OEM) part designed for Samsung refrigerators. Its primary function is to monitor the temperature of the evaporator coils. When the coils reach a specific temperature, the thermostat activates the defrost heater to melt any ice or frost that has built up. This process is crucial for maintaining proper cooling and preventing excessive ice accumulation. The thermostat operates in both the fresh food and freezer sections of the refrigerator to manage the defrost cycle.

Several issues can cause a defrost thermostat to fail. Electrical problems or damage to the thermostat's sensing mechanism are common causes. Additionally, if the thermostat becomes covered in ice or frost, it may not accurately sense the temperature, leading to malfunction.

Common signs of a faulty defrost thermostat include:

- Excessive ice buildup in the freezer section
- Inadequate cooling in the fresh food or freezer sections
- Frost or ice on the evaporator coils
- Improper initiation or completion of the defrost cycle

If you observe any of these symptoms, replacing the defrost thermostat with this genuine OEM part is recommended. This Samsung part is also compatible with Kenmore/Sears appliances.

This part addresses the following issues:
- Refrigerator not shutting off
- Refrigerator too warm
- Frost buildup
