How to Fix / Troubleshooting

Safety first: Unplug immediately and do not continue using the fryer until the source is identified. Risk of fire or electric shock.

External check: Inspect the mains plug for discoloration or heat damage. Try a different outlet to rule out a loose wall socket.
Internal inspection: Remove the cover and look for brown or blackened areas on connectors, wires, and the control board. Pay special attention to the heater and fan terminals.
Tighten/replace connectors: Any loose or discolored spade terminals should be replaced and crimped properly. Do not reuse burnt connectors.
Board replacement: If the smell comes from the control PCB and you see burnt components, replace the entire board.
Professional service: Because this involves mains wiring, if you are unsure, have a qualified technician perform the repair.

Persistent electrical burning smell even with a clean interior.
