How to Fix / Troubleshooting
Safety first: Unplug the Klarstein air fryer before opening the housing.
Steps:
- 1. Confirm issue: Compare the fryer timer to a stopwatch over a 10–15 minute cycle.
- 2. Power stability: Ensure the fryer is on a stable mains supply, not a long undersized extension cord.
- 3. Inspect control board: Open the housing and look for damaged components near the microcontroller and crystal/oscillator. Replace the main control board if any are suspect.
- 4. Firmware: If the issue appeared after a board replacement, verify that the correct board version for your Klarstein model was installed.
Warning: Timing errors can lead to undercooked food; adjust cooking times manually until repaired.
