General Electric Refrigerator MSG27DHTCWH Fridge too warm

The Defrost Thermostat is an OEM part for GE refrigerators. It regulates the temperature of the defrost cycle by sensing the temperature of the evaporator coils and signaling the defrost heater to turn on or off. This helps prevent ice buildup on the coils, ensuring efficient cooling and proper refrigerator operation.

You should replace this defrost thermostat if it fails to regulate the defrost cycle correctly. Common causes of a bad thermostat include electrical failures, wear and tear from regular use, or damage from temperature fluctuations.

Symptoms of a bad defrost thermostat include:

• Excessive frost buildup in the freezer
• Refrigerator not maintaining the correct temperature
• Defrost cycle not activating
• Water leaking inside the refrigerator

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

This defrost heater and thermostat assembly melts frost from the evaporator and shuts off at the proper temperature during the defrost cycle, restoring airflow and helping the refrigerator maintain steady, reliable cooling performance.

• Heats the evaporator to clear frost/ice during the automatic defrost cycle
• Thermostat opens to terminate heat once a safe temperature is reached
• Helps restore air circulation to the fresh food section
• Common failure signs: heavy frost on the freezer back wall/evaporator, poor cooling or warm fridge, fan noise from ice contact, little or no water in the drain pan after "defrosts"

• Disconnect power before service; work on a fully de-energized appliance
• Access is typically behind the freezer's rear panel; remove shelves/ice components as needed
• Fully defrost before installing the new assembly to prevent damage and ensure proper fit
• Reinstall in the original locations; clamp the thermostat to the evaporator tubing and route wiring exactly as factory, away from sharp edges and moving parts

The Ice Door Assembly is an OEM part for GE refrigerators. It is integral to the ice dispenser system, controlling access to the ice chute. This component ensures the efficient delivery of ice cubes or crushed ice when activated and seals off the chute when not in use to maintain the freezer's temperature and prevent frost buildup.

Symptoms of a bad Ice Door Assembly include:

• Frost or ice buildup around the dispenser area
• Ice escaping from the dispenser when not in use
• Failure to dispense ice
• Noise during operation indicating misalignment or malfunction

Causes of a bad Ice Door Assembly can include mechanical wear from frequent use, failure of the spring mechanism or solenoid that operates the door, or damage to the sealing surfaces that leads to air leaks.
