What Does Error C Mean?

The KitchenAid range hood C error signifies that the charcoal filter needs cleaning or replacement. This alert appears after approximately 100-120 hours of fan operation and may come with unusual noises or a failure to operate properly. To resolve this, clean or replace the charcoal filter and reset the reminder. If the C error persists after maintenance, further investigation into the fan motor or control board may be necessary.

Common Symptoms:

  • Letter "C" appears on display when fan operation is stopped
  • Reminder occurs after prolonged use
  • Filter saturation alarm may trigger regardless of other faults

Possible Causes

  • Charcoal (recirculating) filter saturation or need for cleaning/replacement (high)
  • Standard filter maintenance reminder after regular use (high)
