Timer counts down too fast or too slow compared to real time.

Safety first: Unplug the unit before internal inspection.

Steps to verify and address timing issues:

• Confirm discrepancy: Use a stopwatch to compare the air fryer timer with real time over a 10–15 minute period.
• Power reset: Unplug for 10 minutes and retest; minor glitches can sometimes be cleared.
• Check power stability: Ensure the unit is not sharing a circuit with heavy loads that cause voltage dips.
• Board replacement: If the timer remains inaccurate, the internal clock circuit on the main control PCB is likely defective. Replace the PCB.

Note: Slight timing variation (a minute or two over long cycles) is usually acceptable; large errors indicate a fault.
