How to Fix / Troubleshooting
Safety first: Some warmth is normal, but surfaces should not cause burns. Keep children away during operation.
- Check placement: Ensure at least several inches of clearance around the cooker for airflow.
- Inspect inner pot seating: Make sure the pot is fully inserted and not tilted.
- Inspect insulation: With the unit unplugged and cool, remove the outer shell (if serviceable) and inspect the fiberglass or foil insulation around the inner chamber. Replace any missing or burned insulation with high‑temperature rated material.
- Service if severe: If the exterior becomes dangerously hot, discontinue use and have the cooker inspected professionally.
