Finding out why the walls of your Sanyo freestanding freezer are hot
It's normal for the outer walls of the freezer to get warm or hot when the compressor is running; refrigerant lines inside the cabinet walls remove heat from the compressed refrigerant. The hot refrigerant helps control cabinet humidity to prevent the cabinet from sweating.
If the walls get extremely hot, the condenser fan could be malfunctioning. The condenser fan blows air across the condenser coils to help cool the compressed refrigerant before it enters the evaporator. Replace the condenser fan if it doesn't run when activated.
Dirty condenser coils can also cause the hot freezer walls. Dust build-up on condenser coils interferes with heat transfer so the refrigerant stays hotter as it leaves the condenser and travels through lines in the freezer walls.
Performing routine maintenance on the freezer can also help keep the freezer walls from getting hot. Cleaning dust from the compressor compartment grill can improve airflow across the condenser so the refrigerant is cooler as it goes through lines in the freezer walls. Cleaning replacing the lid gasket can prevent air from leaking into the freezer compartment, causing the compressor to run longer and heating up the refrigerant travelling through lines in the freezer wall.
Replacing the compressor start relay on your Sanyo freestanding freezer
- Unplug the freezer or shut off the circuit breaker for the freezer to disconnect electrical power.
- Pull the control knob straight off of the cold control thermostat. Remove the screws securing the compressor grille cover to the freezer cabinet. Hinge the grille cover down to access the back of the cold control thermostat. Squeeze together the 2 locking tabs that secure the cold control thermostat to the compressor grille cover and release the cold control thermostat from the grille.
- Squeeze the wire harness plug to release the locking tabs and remove the wire harness from the compressor start relay.
- Release the wire retainer from the compressor start relay. Grasp the compressor start relay firmly and pull it out of the connection terminals on the compressor.
- Position the new compressor start relay next to the compressor and line up the terminal prong connections. Push the compressor start relay onto the compressor terminal prongs. Reinstall the wire retainer on the start relay.
- Push the wire harness plug into the start relay. Make sure that the locking tabs snap into place.
- Position the cold control thermostat on the compressor grille cover and push it into the grille cover. Make sure that the locking tabs on the cold control thermostat snap into place on the grille cover. Position the control knob on the front of the cold control thermostat and push the control knob down on the stem of the cold control thermostat. Position the compressor grille cover properly on the freezer cabinet and secure it using the mounting screws.
- Plug in the freezer or turn on the house circuit breaker to restore electrical power.
