General Electric Refrigerator GFSS2KEYCSS Freezer too cold

The Defrost Thermostat is an OEM replacement part designed for use in GE refrigerators. This component acts as a safety device in the refrigerator's defrost system, preventing the freezer from overheating during the defrost cycle. It works by monitoring the temperature of the evaporator coil and turning off the defrost heater when the coil gets warm enough, thus safeguarding the freezer from getting too hot.  

Causes of a bad defrost thermostat can include corrosion, a blown fuse inside the thermostat, or wear and tear over time, which can lead to malfunctioning of the refrigerator's defrost system.

Symptoms of a bad Defrost Thermostat include:

• Frost buildup on the back wall of the freezer
• The refrigerator is not cooling properly
• The freezer is cold but the refrigerator is warm
• The defrost heater not turning on

This GE replacement part is also compatible with Hotpoint, RCA, and some Kenmore models.

The Temperature Sensor is an OEM replacement part for GE refrigerators, designed to accurately monitor and relay the temperature inside the refrigerator and freezer compartments to the electronic control board. By detecting the slightest changes in internal temperature, the sensor allows the control board to make real-time adjustments to the cooling system, activating the compressor and fans as needed to maintain optimal conditions for food preservation.

Over time, the temperature sensor can fail due to electrical issues, exposure to moisture, or general wear and tear. A malfunctioning sensor can lead to improper temperature regulation, affecting the efficiency of the refrigerator and the freshness of stored food.

Symptoms of a bad Temperature Sensor include:

• The refrigerator or freezer not maintaining the set temperature 
• The appliance running continuously or more frequently than normal
• Inaccurate temperature readings displayed  

This OEM GE part can also be used on Hotpoint, RCA, and Kenmore/Sears appliances.
