Unlike upright freezers that will typically have a fan to help remove the heat from the condenser, chest freezers dissipate the heat from the condenser coils through the cabinet. It is normal for the outer cabinet to be warm.
Top Solution
02 - Condenser Coils are Dirty
If the condenser coils are located within the freezer walls, the coils do not require cleaning. However, if the condenser coils can be readily accessed from behind or under the unit, you should clean them every 6 to 12 months by using a soft bristle brush (or a dedicated condenser coil cleaning brush) to wipe off the coils in a circular motion. A vacuum cleaner with a nozzle attachment can also be used for hard-to-reach areas.
Highly Likely
03 - Freezer Condenser Fan Motor
The condenser fan motor cools the condenser coils and compressor when it’s running. A defective fan motor that doesn't work will result in the condenser coil, compressor, and any tubing in the cabinet walls to become very hot. Try rotating the fan blades by hand. If the blades don't turn easily, the motor has seized and will need to be replaced. You can also use a multimeter to test the fan motor for electrical continuity. If the motor tests negative for continuity, you'll know the component has failed.
