How to Fix / Troubleshooting
Safety first: Immediately unplug the unit if you smell burning plastic or electrical odor. Do not continue using it until inspected.

- Open housing: Remove the outer cover to inspect internal wiring around the heating element and main control PCB.
- Look for damage: Identify any discolored, melted, or charred wires and connectors. Check the PCB for burnt components.
- Repair wiring: Replace any damaged high-temperature wires with equivalent heat-resistant wiring and new connectors.
- Replace damaged assemblies: If the PCB or heater terminals are burned, replace the main control PCB or heating element assembly as appropriate.
