What F
actually means.
JennAir's display hoods log how long the fan has run. After 30 hours they flag the metal grease filters with an F that shows only while the fan is working. The letter is a maintenance flag set by a timer, and it stays until someone holds the reset.

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.
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.

JennAir hoods and downdraft vents are diagnosed at home, with the lift, the blower and the touch controls each tested on the call.
SourceJennAir Product Help: F - Displayed (vent hoods)
JennAir's help site lists F for its display vent hoods without naming the models; JennAir telescoping downdrafts (JXD7030Y, JXD7036Y) use a slider and have no display.
Before you book,
in this order.
Each step comes from JennAir's own guidance for F on its range hoods. Follow it to the end: the last card says whether this is a visit.
Switch the fan off, wait for the hood to cool and take the metal grease filters down.
Clean them in the dishwasher or a hot detergent soak and let them dry thoroughly before refitting.
Hold FAN for 3 seconds to clear the alarm.
Book a visit if the F cannot be cleared or reappears the next time the fan starts.
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 JennAir F on the hood is not a numbered error code and does not report a failed blower or board. JennAir's F-codes on its cooking surfaces and microwave hood combinations are a different system and do not apply to a vent hood.

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 JennAir's own words
After 30 hours of fan operation, the display will show “F” when the fan is active.

about F.
Can I clear F myself?
Is F on my JennAir hood the same as an F error on my JennAir burners?
Why does F on my JennAir hood disappear when the fan is off?
Do I need new grease filters when my JennAir hood shows F?
Back to your everyday
Still showing 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.
