What Speed keys flashing
actually means.

The KBTU and KPRU touch panels count hood running time too. After 100 hours, the speed keys start flashing as a reminder to clean the filters, and on a recirculating hood to replace the charcoal.

What to do when Speed keys flashing shows on the range hood

Kind 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.

Usually leads toRange hood filter and baffle service

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

What not to do

Flashing speed keys here are a filter reminder and not a touch sensor failure. Two keys flashing after a three-second hold on the 24h key is the air exchange mode instead.
