Official Frigidaire upright freezer parts

Top repair parts for Frigidaire upright freezers

• Door gasket. The door gasket is a flexible seal that attaches to the outer edge of the freezer door to form an air tight seal around the door opening. The door gasket prevents warm, moist air from leaking into the freezer compartment when the door is shut.
• Temperature control thermostat. The temperature control thermostat is mounted in the control housing area and controls the temperature inside the freezer. It turns the compressor on and off as needed to maintain the set temperature in the freezer. The thermostat has a temperature sensor tube that detects the actual temperature in the freezer compartment and controls the temperature based on the reading from that sensor.
• Defrost timer. The defrost timer controls the intervals between automatic defrost cycles in the freezer. When the timer activates the defrost cycle, the compressor stops, and the defrost heater turns on briefly to melt frost from the evaporator fins to increase the heat-exchange efficiency. After the fins are defrosted, the timer reactivates normal cooling in the freezer.
• Compressor start relay. The compressor start relay starts the compressor and keeps it running until the compressor cycles off.
• Compressor. The compressor is a pump that an electric motor rotates. The compressor is the problem if the motor won't start when the start relay actives it, or if the motor runs but the pump doesn't compress the refrigerant. Have a service technician replace the compressor, because this repair requires access to the sealed refrigerant system.

What to do when you see excessive frost inside your Frigidaire upright freezer

Some frost inside the freezer is normal, because each time you open the freezer door or lid, warm, moist air enters the freezer and forms frost. But if excessive frost forms quickly inside the freezer, it could be that a damaged lid or door seal is constantly allowing warm, moist air into the cabinet, resulting in excessive frost. Check the door or lid seal and replace the seal if damaged.

A crack in the plastic liner inside the freezer cabinet can also allow warm air into the freezer and cause frost. Check the inner liner and repair any cracks using a liner repair kit.

If you see frost on the evaporator cover in the back of the freezer and the freezer isn't cooling well, then a failure in the automatic defrost system could be causing the frost. If the defrost heating element that melts frost off the evaporator fins fails, frost will cake up on the evaporator and interfere with airflow and cooling in the freezer. A failed defrost bi-metal won't allow current to reach the heater so a failed defrost bi-metal will also cause frost on the evaporator and inhibit cooling in the freezer. A failed defrost timer won't advance into the automatic defrost mode so the defrost heating element would never turn on to melt frost off the evaporator. Check the defrost system if you see frost only on the evaporator cover.
