What ON/OFF blue LED flashing
actually means.

Holding the on/off key for more than 3 seconds starts a 24-hour cycle that runs the fan for an hour, rests for three, and repeats. The blue LED flashes while it is active. It ends when you turn the motor off or after 24 hours.

What to do when ON/OFF blue LED flashing shows on the range hood

Kind of codeMode, not a failure

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.

Usually leads toNo repair

Leave it on if you want the kitchen air refreshed through the day.

Shows up asReading a Range Hood Error Code or Blinking Light

A range hood error code may appear as letters and numbers on a display, a light that blinks in a pattern, a filter reminder that will not clear, or a beep with the fan refusing to start.

Before you book,
in this order.

Each step comes from Falmec's own guidance for ON/OFF blue LED flashing on its range hoods. Follow it to the end: the last card says whether this is a visit.

01

Leave it on if you want the kitchen air refreshed through the day.

02

Turn the motor off with its key to end it.

03

If the fan starts by itself with the blue light steady or off, book a visit.

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 fan starting on its own with the blue light flashing is the cycle, not a stuck relay. A steady blue light is just the normal motor-on indication at speed 1.

Questions
about ON/OFF blue LED flashing.

Can I clear ON/OFF blue LED flashing myself?
Leave it on if you want the kitchen air refreshed through the day.
Why does my Falmec turn on every few hours?
The 24-hour cycle is on. It runs the fan for 1 hour, then pauses 3 hours, for a day.
How do I stop the Falmec 24-hour cycle?
Turn the motor off with its key; the cycle also ends on its own after 24 hours.
Did I turn on the 24-hour cycle by accident?
Probably, if the on/off key was held for more than 3 seconds.

Back to your everyday

Still showing ON/OFF blue LED 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.
