If your hood is recirculating (not ducted outside), fit a new charcoal filter behind the vent grille. If it comes back, it needs a visit. ### Do I need a charcoal filter on a ducted KitchenAid hood combination? No, the charcoal filter is for recirculating installs. The reminder still counts, so simply reset it through Setup/Clock. ### How often does the KitchenAid filter message come back? Every six months after each reset, because the count runs on the calendar and not on fan hours. ### The message went away but the fan is still weak. Why? The reminder only tracks time. A fan that stays weak with clean filters and a clear duct points to the motor or a blocked damper, which a technician can check. --- **[Read on the site: KitchenAid Change the Charcoal Filter: the microwave's six-month filter reminder](https://microwaverepair.center/error-codes/kitchenaid-change-charcoal-filter/)** **[Book a visit with MicrowaveRepair.center](https://microwaverepair.center/schedule/)**
