Possible Causes

Stuck cooling fan relay, Faulty temperature sensor near control panel, Software glitch, Misreading of cavity temperature

How to Fix / Troubleshooting

Safety first: Ensure the oven is not overheating; check that external surfaces are only warm, not hot.

Step-by-step checks:

  • Allow full cool-down: Some V-ZUG models keep the fan running until electronics are cool. Wait at least 30–45 minutes.
  • Power reset: If the fan still runs, switch off the breaker for a few minutes, then restore power. If the fan stops and behaves normally afterwards, it may have been a software glitch.
  • Inspect sensor: Have a technician check the temperature sensor used for cooling control and the fan relay on the power board.

When to call a technician: Continuous fan operation even when cold indicates a control fault requiring professional service.
