Freezer has strong chemical or burning plastic smell

Safety first: If you smell burning or see smoke, unplug the freezer immediately and do not continue to operate it.

• Unplug and inspect: After unplugging and allowing components to cool, inspect the rear control board area and compressor compartment for burnt wiring or components.
• Check interior: Look for melted plastic near the defrost heater or light fixtures.
• Do not puncture lines: If you suspect a refrigerant leak (oily residue, hissing), do not attempt to repair lines yourself. Refrigerant handling requires certification.
• Contact service: Any burning smell or suspected leak should be evaluated by a qualified technician before the unit is used again.
