5303918214 Refrigerator Defrost Thermostat Kit

Key Features

• Bimetal defrost thermostat designed to monitor the temperature of the evaporator coils during the defrost cycle.
• Automatic shut-off mechanism that de-terminates power to the defrost heater once coils reach a specific temperature, preventing cabinet overheating.
• Clip-on mounting bracket engineered for secure attachment to the evaporator tubing for accurate thermal sensing.
• Environmental seal featuring moisture-resistant internal components to prevent frost buildup within the thermostat housing.
• Universal wire lead configuration allows for integration with various refrigerator wiring harnesses.

Compatibility & Fitment

• Frigidaire Refrigerators (Standard, Side-by-Side, and Top-Freezer models)
• Kenmore / Sears (Prefixes 253, 582, 605, 719)
• Electrolux Refrigerators
• Gibson, Kelvinator, Tappan, and Westinghouse models

When to Replace

• Evaporator Frost Buildup: Heavy ice accumulation on the rear panel of the freezer, blocking airflow.
• Temperature Fluctuations: The refrigerator section is too warm while the freezer section is cold.
• Continuous Operation: The refrigerator runs constantly without entering a defrost cycle.
• Visual Deformity: The thermostat casing appears "bulged," swollen, or cracked, indicating internal failure.
• Electrical Continuity: The part fails a multimeter test (no continuity when reaching "closed" temperature).

Installation Tips

• Disconnect the refrigerator from the power source before beginning any repairs.
• Remove the freezer's rear evaporator cover panel to access the coils and the existing thermostat.
• Since this kit may require splicing, use waterproof heat-shrink butt connectors or wire nuts to protect electrical joins from high-moisture environments.
• Secure the thermostat clip firmly to the suction line or the evaporator coil as specified by the manufacturer's original placement.
• Organize and secure wiring away from the sharp edges of the evaporator fins to prevent insulation damage during thermal expansion.
