Strong chemical or burning plastic smell during operation, not typical wood smoke.

Safety first: Turn the grill off, unplug it immediately, and allow it to cool. Do not continue operating if you smell burning plastic or insulation.

• Visual inspection: Remove access panels and inspect wiring harnesses, connectors, and the control board for melted insulation or burn marks.
• Check motor housings: Smell near the auger and fan motors (when cool) to identify any burnt odor from failing windings.
• Repair damaged wiring: Replace any harnesses with melted insulation. Do not tape over severely damaged wires; use proper replacement parts.
• Replace overheated components: If a motor or the control board shows signs of overheating or burning, replace the affected part.
• Test carefully: After repairs, run the grill under supervision and be prepared to disconnect power if the smell returns.
