Possible Causes
Faulty oscillator on main PCB, Firmware bug, Voltage instability affecting timing circuit
How to Fix / Troubleshooting
Safety first: Unplug before opening the control housing.
Steps to evaluate:
- Confirm symptom: Compare the air fryer timer against a stopwatch over a 10–15 minute period.
- Power stability: Ensure the unit is connected directly to a stable mains outlet, not a long extension cord.
- Board inspection: Open the control area and inspect the main PCB for damaged timing components (crystal oscillator, resonator). These are small metal cans or ceramic parts near the microcontroller.
- Board replacement: Timing components are not usually serviced individually. Replace the main control board if the timer is significantly inaccurate.
