Neff oven shows E017 and the cooling fan runs continuously or not at all
Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Isolate the oven from mains before accessing the top or rear panels.
- Observe fan behavior: After switching the oven off, the cooling fan should run for a short time then stop. If it never runs or runs indefinitely with E017, suspect a control issue.
- Check fan motor: Access the cooling fan (usually at the top rear of the oven). Spin the blades by hand to ensure they move freely. Check for noise or stiffness.
- Continuity test: Measure resistance across the cooling fan motor. An open circuit indicates a failed motor.
- Wiring and relay: Inspect wiring from the fan to the PCB. Look for burnt connectors. On the PCB, check the cooling fan relay for signs of overheating.
Replace the cooling fan motor if open-circuit or seized. If the motor is good but not controlled correctly, the relay or main control board may need replacement.
