Unusual burning smell during operation, even when food is not burnt.

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

• 1. Check for food spills: Remove the inner pot and inspect the heating plate and outer shell for spilled food or oil. Clean thoroughly.
• 2. New unit burn-in: Mild odor during the first few uses can be normal. Run a water-only cycle with a bit of vinegar to help dissipate.
• 3. Inspect internal wiring (advanced): Remove the bottom cover and look for discolored insulation, melted plastic, or burned connectors. Replace any damaged wiring or terminals.
• 4. Verify ventilation: Ensure the cooker has adequate space around it and that bottom vents are not blocked.

Persistent strong burning smell without visible cause indicates a failing component; discontinue use and have the unit serviced.
