Possible Causes

How to Fix / Troubleshooting
Safety first: Unplug the air fryer before opening the housing.
Steps to troubleshoot non-running heater and fan:
- Confirm safety interlocks: Ensure the drawer is fully inserted and the basket safety switch is functioning (see E8 scenario).
- Inspect output wiring: Remove the bottom cover and trace wires from the control PCB to the heater and fan. Ensure all connectors are firmly seated.
- Check for board damage: Look for burnt or cracked solder joints around the heater and fan relays or triacs.
- Replace control board: If the timer and display work but neither heater nor fan receive power, the main control PCB is likely defective. Replace it with a Kalorik-specific board.
Because both outputs are affected, focus on the common control electronics rather than individual components.
