General Electric Refrigerator HTT15BBMBRCC Freezer not defrosting

The Defrost Heater is an OEM part for GE refrigerators. This part melts away frost that accumulates on the evaporator coils during the cooling cycle. This process is vital for maintaining the efficiency of the refrigerator, ensuring that air can flow freely over the coils to keep the unit cooling effectively. 

Causes of a bad defrost heater can include a faulty heater element, electrical issues preventing the heater from activating, or damage to the heater's wiring.  

Symptoms of a bad Defrost Heater include:

• Frost buildup on the evaporator coils
• The refrigerator or freezer section is too warm
• The refrigerator is running constantly without cycling off
• Pools of water or ice on the floor of the freezer compartment

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

The Defrost Thermostat is an OEM part for GE refrigerators. It plays a critical role in the refrigerator's defrost system, preventing frost build-up on the evaporator coils by turning the defrost heater on and off at appropriate times. This component is designed to sense the temperature of the evaporator coils and activate the defrost heater when the coils get too cold, ensuring efficient operation and optimal cooling performance.

Symptoms of a bad Defrost Thermostat include:

• Excessive frost or ice accumulation in the freezer compartment
• The refrigerator or freezer section becoming too warm
• The defrost heater not activating, leading to reduced efficiency

Causes of a bad defrost thermostat can include damage from moisture or ice, electrical failures within the thermostat, or simply wear and tear from regular use.

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