Questions
about F4.

Can I clear F4 myself?
Wait for the electronics to cool. If it comes back, it needs a visit.
Why did every zone on my Thermador shut off at once?
F4 means the electronics as a whole overheated, so all zones stop until they cool.
Is F4 on a Thermador a sign of a failing fan?
It can be when it happens often at ordinary settings. A technician checks the cooling path.
