• Door Seals: Inspect the door gaskets for wear and tear and make sure the doors close properly.
• Evaporator Fan: Check the fan for any obstructions.
• Condenser Fan: The condenser fan helps dissipate heat from the condenser coils. If the fan motor is not running, the refrigerator may not cool properly.
• Defrost System: If the refrigerator an ice buildup problem on the evaporator coils. Check the defrost heater, defrost thermostat, and defrost timer to see which one is faulty.
• Thermistor: A refrigerator may not maintain the correct temperature sometimes due to a faulty thermistor. Check the thermistor to make sure it is not malfunctioning.
