Smoker overheats well beyond the set temperature; food burns even at low settings.

Safety: Unplug the smoker immediately if it is overheating. Keep the door closed until internal flames (if any) are out, then open carefully to vent smoke.

Steps:

• After cooling, inspect the thermostat or electronic control. If mechanical, check for a stuck shaft or knob. If digital, suspect a stuck relay on the control board.
• Test the thermostat with a meter for continuity. It should open when turned to OFF. If it remains closed, replace it.
• Inspect the control board heater relay for signs of welding or burning. Replace the board if the relay is stuck on.
• Verify the high‑limit thermostat is present and wired correctly. Replace it if it does not open at its rated temperature (requires bench testing or replacement by a technician).

Warning: Do not operate the smoker until the cause of overheating is corrected; fire risk is significant.
