The oven fan continues after cooking has ended

Identify which sound you are hearing and when it began. A fan heard after switching the cooking mode off is different from a scraping sound inside the cavity or a ventilation hood running above the range. Note whether the oven was recently used at a high temperature and whether the sound gradually changes as it cools.

Thermador explains that an oven cooling fan may continue until the appliance has cooled sufficiently. Do not block the vent or cut power simply to silence an ordinary cooling period. There is no single universal running time for every model, program and kitchen condition, so compare the behavior with the manual and your appliance’s usual pattern.

A new harsh noise, a fan that starts when the oven has not been used, or operation that persists after the appliance is fully cool should be reported. Include any error message or change in heating. Keep hands and tools away from vents and internal fan areas; a sound recording from a safe distance is enough for the initial request.

Useful observations before you call

• Record the cooking mode and approximately when it was switched off.
• Describe whether the noise is steady airflow, rattling, scraping or intermittent starting.
• Note any visible vent obstruction without removing trim or reaching into the appliance.
