Possible Causes
Heater relay contacts welded closed, Firmware glitch in main PCB, Mechanical timer not returning to off position, Shorted control transistor on PCB
How to Fix / Troubleshooting
Safety first: If the unit does not shut off, unplug it immediately to prevent overheating or fire.
- Test behavior: After cooling, plug in and start a short cycle while monitoring. If the heater or fan continues after the timer ends, do not use the fryer until repaired.
- Mechanical timer models: Ensure the timer knob returns fully to the off position. If it sticks, replace the timer.
- Electronic models: Inspect the main PCB for a heater relay stuck closed (contacts welded). A technician can test and replace the relay, but full PCB replacement is usually recommended.
Do not leave the air fryer unattended if it has shown this behavior; it is a serious safety fault.
