What F
actually means.
Zephyr hoods with a one-character display count fan hours and flash F once 30 hours have built up. The metal mesh filters are holding enough grease that airflow and the blower can suffer if they are left. Zephyr's help center describes a flashing F the same way: a clean filter reminder, not a breakdown.

What to do when 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 Zephyr's own guidance for F on its range hoods. Follow it to the end: the last card says whether this is a visit.
Turn the hood off, let the filters cool and release them from the hood.
Wash them by hand with a grease-cutting soap or in the dishwasher, and let them dry fully before refitting.
With the hood off, hold the button shown in your manual for about 5 seconds until the F disappears to restart the 30-hour count.
If the F comes back right after a reset, book a visit to check the control.
Still there?
It usually turns into range hood filter and baffle service. Book with the code and the model number.
What not to do
A flashing C on the same display means the charcoal filters need replacing, which is a different job. An F that shows steady while you change speeds is part of normal operation only if your manual says so; the reminder itself flashes.

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 Zephyr's own words
After every 30 hours of use the display will start flashing an F reminding you to clean the metal filters

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.
