Persistent chemical or melting plastic smell during every use, sometimes with visible discoloration of housing.

Safety first: Unplug the cooker and discontinue use until the cause is identified. Risk of fire exists.

• External inspection: Look for discoloration or warping of plastic near the base or vents.
• Open base (advanced): Inspect wiring harness routing. Ensure no wires or plastic clips are in direct contact with the heating plate.
• Check insulation and shields: Verify that heat shields are correctly installed and not displaced.
• Replace damaged parts: Replace any melted plastic components, reroute wiring, and replace the heating plate or insulation if they caused the overheating.
