General Electric Refrigerator TBE21DATNRWH Freezer not defrosting

The Defrost Timer is an OEM part for GE refrigerators. This part manages the defrost cycle of the fridge and freezer compartments, ensuring that the evaporator coils do not build up excessive frost. 

This cycling is crucial for maintaining optimal temperatures for food preservation and energy efficiency. Over time, the defrost timer can malfunction due to wear, electrical issues, or a buildup of dust and debris, leading to poor performance or failure.

Symptoms of a bad Defrost Timer include:

• Frost buildup in the freezer compartment
• The refrigerator or freezer is not maintaining the set temperature
• The fridge or freezer sections are too warm
• The defrost cycle does not activate, leading to reduced cooling efficiency

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

The Defrost Thermostat is an OEM part for GE refrigerators. This component plays a crucial role in the defrost system by regulating the temperature within the freezer. It ensures the defrost heater activates when the temperature rises above a certain threshold, preventing ice build-up on the evaporator coils and maintaining efficient cooling.

Over time, the defrost thermostat can fail due to electrical issues, prolonged exposure to extreme temperatures, or wear and tear from regular use. When this part fails, it can lead to improper defrost cycles, causing ice accumulation and reducing the refrigerator's efficiency.

Symptoms of a bad defrost thermostat include:

• Excessive frost buildup in the freezer
• Inconsistent temperatures in the refrigerator and freezer compartments
• Refrigerator running continuously or not running at all
• Leaking water inside the fridge due to melted ice

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