Possible Causes
Failed cooling fan with tachometer output, Broken tachometer wire, Faulty fan speed control circuit on main board, Obstructed fan causing incorrect speed feedback
How to Fix / Troubleshooting
Safety first: Disconnect power and wait for the oven to cool.
- Inspect the cooling fan: Access the fan from the top/rear. Check that it spins freely and is not obstructed by insulation or wiring.
- Check tachometer wiring: On models with a 3-wire fan, ensure the third (signal) wire is intact and properly connected to the control board.
- Replace the fan: If the fan is noisy, seized, or its tachometer output is not present (requires advanced testing), replace the cooling fan assembly with the correct Hansa part.
- Control board: If a known-good fan still triggers E16, the speed control circuit on the board may be defective.
When to call a technician: Variable-speed fan diagnostics often require specialized knowledge; professional service is recommended.
