Neff oven cooling fan continues to run for a very long time after cooking has finished

Safety first: No immediate hazard, but disconnect power before internal checks.

• Allow full cool-down: It is normal for the cooling fan to run for some time after use, especially after high temperatures. If it runs for more than an hour, suspect a fault.
• Check installation: Ensure cabinet ventilation meets Neff specifications.
• Sensor and relay: Have a technician test the control panel temperature sensor and cooling fan relay for correct operation.
