Freezer: Outer walls 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 bottom front grill can improve airflow across the condenser so the refrigerant is cooler as it goes through lines in the freezer walls. Cleaning the door or 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.

These repairs may help solve your Freezer problem:

Replace the freezer condenser fan motor

Condenser fan

The condenser fan is in the machine compartment of the freezer next to the compressor. It moves air across the condenser coils to help cool the hot refrigerant coming out of the compressor. Replace the condenser fan if it fails to run when activated.

Perform freezer routine maintenance

Drain pan

Routine maintenance keeps your freezer working efficiently. Clean the bottom front grill and the condenser coils regularly to help the freezer cool better and use less energy. Adjust the freezer door if it’s not sealing properly. Lubricate the door seal with a light coat of petroleum jelly occasionally to prevent air leaks into the freezer.

Clean the freezer condenser coils

Condenser

Dust-covered freezer coils prevent the freezer from running efficiently and cooling properly. Unplug the freezer and clean the condenser coils using a coil brush. Vacuum up the dust. Clean the grill below the freezer door to allow proper air flow to the condenser.
