Three short steps, about a minute.

Before you book,
in this order.

Each step comes from Bertazzoni's own guidance for T4 flashing on its range hoods. Follow it to the end: the last card says whether this is a visit.

01

Let the six minutes run out, or press another speed key to change it sooner.

02

If the hood turned off after intensive speed, that is normal when it was started from off.

03

If T4 flashes but the blower does not speed up, book a visit to check the blower.

Cleared?

The code is gone and the blower pulls steam up on every speed again without a new part. If it returns this week, or the filter reminder keeps coming back right after a cleaning, mention it in the booking.

What not to do

A flashing T4 is not an alarm about the motor or the keypad. The hood switching off at the end of intensive speed is also by design when it was started from off.

What you may
notice with it.

The range hood problems T4 flashing tends to arrive with. Answer these at the range hood before anyone is booked.

All problems

No repair indicated

Nothing to repair.

The hood is doing something it was told to do, not wearing out: a delay-off timer that keeps the blower running for some minutes after the burners go off, a heat sentry that starts the fan by itself when it senses a hot pan, a Sabbath setting that locks the keys and dims the lights, or a link to the cooking surface that sets the speed on its own. No part is needed; a key sequence from the manual, or simply waiting, ends it.

Questions
about T4 flashing.

Can I clear T4 flashing myself?
Let the six minutes run out, or press another speed key to change it sooner.
Why did my Bertazzoni hood switch off on its own after a few minutes?
Intensive speed was probably started with the blower off. After six minutes it ends and the hood goes off.
How long does intensive speed last on a Bertazzoni KMC?
Six minutes, then it drops back to the previous speed.
Can I keep the intensive speed on longer on my Bertazzoni?
Press T4 again when it ends. There is no setting to make it run continuously.

Back to your everyday

Still showing T4 flashing?

Three things make the booking useful: the letters or blink pattern exactly as they showed, the full model number from the label behind the filters, and whether the fan still moves air on every speed. With those, the technician arrives with half the answer already worked out.
