Frigidaire Refrigerator Defrost Thermostat Kit 5303918202

Genuine OEM refrigerator defrost thermostat kit. The thermostat protects the evaporator from overheating during the defrost cycle and helps prevent frost buildup.

Is This the Right Part?

Common Symptoms

• Freezer not defrosting
• Refrigerator section too warm
• Freezer section too warm
• Reduced cooling caused by frost-covered evaporator coils
• Refrigerator running excessively while cooling performance declines

Check Before Replacing

• Disconnect power before accessing the freezer evaporator or thermostat.
• Visually inspect for heavy frost or ice covering the evaporator coils; heavy, uniform frost can indicate a defrost-system problem but does not by itself prove thermostat failure.
• With the thermostat disconnected from the circuit and at a temperature below its closing point, check continuity with a multimeter; lack of continuity under the correct cold condition suggests the thermostat may be defective.
• Check the defrost heater and related wiring separately, because a failed heater, timer, control, wiring, or blocked airflow can produce similar symptoms.
