The board houses the light bulbs. The light board has an electronic circuit board that controls the light bulb's voltage. When the electronic circuit board is malfunctioning, you can see a burn mark. If the light board doesn't light up, replace it.
The compressor start relay is used to start the compressor. If the compressor doesn't run, replace the start relay. Repairing the start relay wiring will fix the problem if the wiring fails.
The door seal is attached to the door panel of the upright freezer and the lid is attached to the chest freezer. The seal keeps air out of the freezer when the door is shut. When the door or lid is closed, a damaged seal lets warm, moist air into the freezer. The door seal should be replaced if it is damaged.
The freezer defrost sensor is located next to the evaporator. It goes when the temperature in the evaporator is too high. The defrost bi-metal shuts off when it travels. A malfunctioning defrost bi-metal causes frost to build up on the evaporator and causes a warmer freezer interior. The defrost sensor should be replaced if it prevents the heater from working.
The freezer has a temperature sensor. The control board uses the thermistor to read the temperature in the freezer. If the thermistor isn't accurate, replace it.
Follow these steps to fix your issue:
Shut off the power
Shut off the circuit breaker for the freezer. While the freezer is shut off, store any food that could degrade. The new gasket should be soaked in warm water to smooth it out. On a low heat setting, you can use a heat gun or hair dryer.
Remove the lid gasket
The freezer lid needs to be raised. To access the screws and clips that secure the gasket to the freezer lid, fold the inside lip of the gasket back. The screws need to be removed from the gasket. To get the plastic clips out of the gasket, use a slot screwdriver. The outer lid panel has a gasket and inner lid liner. The inner lid liner has a gasket on it.
Install the new lid gasket
The inner lid liner has a gasket around it. Line up the mounting holes with the help of the inner lid liner and gasket. Attach the gasket and inner lid liner to the outer lid panel with screws and clips.
Check the new lid gasket for a proper seal
Check the gasket for a proper seal when you lower the lid. There are no gaps between the lid gasket and the top edge of the freezer cabinet when the lid is closed.
Lubricate the new lid gasket
To protect the lid gasket from wear, coat it lightly with petroleum jelly.
Disconnect the electrical power
Shut off the circuit breaker for the freezer if you want to unplug it.
Remove the grille cover
Pull the control knob from the thermostat. The compressor grille cover needs to be removed. To get to the back of the thermostat, you have to open the grille cover. The cold control thermostat must be secured to the compressor grille cover by squeezing together the 2 locking tabs.
Disconnect the wires from the compressor start relay
Remove the wire harness from the compressor start relay and release the locking tabs by squeezing the wire harness plug.
Remove the compressor start relay
There is a wire retainer in the compressor start relay. Pull the compressor start relay out of the connection terminal.
Install the new compressor start relay
The compressor start relay should be positioned next to the compressor. The compressor start relay needs to be pushed onto the compressor terminal. Remove the wire retainer from the start relay.
Reconnect the wires to the compressor start relay
The start relay has a wire harness plug. Make sure the locking tabs are in place.
Reinstall the grille cover
Push the cold control thermostat into the compressor grille cover. Attach the locking tabs on the thermostat to the grille cover. Push the control knob down on the stem of the cold control thermostat when you position the control knob on the front of the thermostat. Use the mounting screws to secure the compressor grille cover on the freezer cabinet.
Restore electrical power
You can restore power by plugging in the freezer or the house circuit breaker.
You would need the following tools:
petroleum jelly, phillips screwdriver, pliers, slot screwdriver, work gloves.
