Freezer emits a strong chemical, burning, or plastic smell when running.

Critical safety warning: If you smell burning plastic or see smoke, unplug the freezer immediately and do not continue to operate it until inspected.

Steps to investigate odor:

• Unplug and inspect rear: Remove the rear lower panel and look for discolored or melted components near the compressor and control board.
• Check start relay and overload: Smell the compressor start device; a burnt odor often indicates failure. Replace with a compatible Costway start relay/overload.
• Inspect wiring: Look for melted insulation or burnt connectors. Any damaged wiring should be repaired or replaced by a qualified technician.
• Clean condenser: Dust on hot condenser coils can produce an odor when first heated. Clean coils with a brush and vacuum.

Do not: Ignore persistent burning smells. Continued operation can be a fire hazard.
