Safety first: Surfaces may be hot but should not cause burns. If there is a burning smell, unplug immediately.

Steps:

Improve ventilation: Ensure adequate clearance around the freezer, especially at the back and sides. Do not block air vents.
Clean condenser area: Remove dust and lint from the rear and bottom of the unit using a vacuum and brush.
Check condenser fan: On models with an external condenser fan, verify it runs when the compressor is on. Replace if not (see condenser fan entry).
Monitor temperature: Some warmth is normal, especially along door edges, but surfaces should not be excessively hot for long periods.

Freezer exterior sides or top feel very hot to the touch.
