Possible Causes

New appliance off-gassing, Dust burning off condenser, Overheating wiring or control board, Food spill on heater or warm components

How to Fix / Troubleshooting

Safety first: If you smell burning plastic or see smoke, unplug the freezer immediately and do not use it until inspected.

  • 1. New appliance smell: Mild plastic odor is normal for a new SMEG freezer and should dissipate within a few days. Ventilate the area and keep the door slightly open when empty (with power off) to air out.
  • 2. Clean condenser area: Unplug the unit and vacuum dust from the condenser coils and compressor area, which can cause burning smells when heated.
  • 3. Inspect wiring and PCB: Remove the rear panel and check for burnt insulation, melted connectors, or scorched areas on the main control board. If found, discontinue use and arrange professional repair.
  • 4. Check interior for spills: Clean any spilled food or packaging material that may have contacted warm components.
