What C F
actually means.
When a KG hood runs in recirculating mode, its charcoal filters wear out after a longer stretch of use than the grease filters. The display then alternates between C and F to ask for a change of charcoal filters, and the grease filters should be washed at the same time.

What to do when C F shows on the range hoodKind of codeFilter reminders
The hood has counted enough hours of fan time to ask for its filters: the mesh or baffle grease filters want a wash, or on a recirculating hood the charcoal filters want replacing. Most hoods count hours rather than measure grease, so the light comes on whether the filters are clean or not, and it stays on until it is reset with the key the manual names. A reminder that returns straight after a reset, or a hood that still pulls weakly with fresh filters, is worth a visit.

Cleaning or replacing what catches grease and odor: mesh and baffle filters, charcoal pads on recirculating hoods, and the grease channel.

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 Bertazzoni's own guidance for C F on its range hoods. Follow it to the end: the last card says whether this is a visit.
Take out the grease filters and wash them.
Replace the charcoal filters with the kit listed for your KG model; they cannot be washed.
With everything back in place, hold button B for about five seconds until the display stops flashing.
If the alternating C and F returns within days, book a visit to check the control.

It usually turns into range hood filter and baffle service. Book with the code and the model number.
What not to do
This reminder only matters on a KG hood set up to recirculate air back into the kitchen; on a ducted hood there is no charcoal to change. A steady C with the motor off is something else, the clean air mode, and not a filter request.

Filter reminders on other makes
Wall-mount range hood
The chimney hood fixed to a bare stretch of wall above the burners, its canopy catching the rising smoke while a telescoping cover hides the duct that climbs to the ceiling.
Under-cabinet range hood
The slim hood screwed to the bottom of the wall cabinet over the burners, venting up through that cabinet or back through the wall, or cleaning the air and returning it to the room.
Island range hood
The hood that hangs from the ceiling over burners set into a kitchen island, open on all four sides, with its duct and wiring hidden inside a chimney that drops from above.
In Bertazzoni's own words
When display item C flashes, at a speed where it alternates with the letter C and F, the carbon filters must be replaced.

Still showing C F?
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.
