Outer housing becomes excessively hot to the touch during normal operation.

Safety first: Avoid touching hot metal surfaces; use handles only. Unplug and cool before inspection.

• Check placement: Ensure the cooker is not placed in a confined space or against walls that reflect heat back.
• Inspect inner pot fit: Confirm the pot sits correctly and the lid seals well, minimizing heat loss.
• Open housing: If comfortable, remove the outer shell to inspect internal insulation material around the inner pot. Replace any burnt or missing insulation.
• Monitor temperatures: Some warmth is normal, but if surfaces are too hot to touch briefly, discontinue use and have the unit inspected professionally.
