How to Fix Error C

DIY Fix Clean or Replace Activated Carbon Filter

  1. Identify if your hood uses a charcoal (activated carbon) filter (common in recirculation/ductless mode).
  2. Remove the activated carbon filter according to your model’s instructions.
  3. If the filter is reusable (rare), clean it as specified; otherwise replace it with a new genuine filter.
  4. After cleaning/replacing, reset the filter reminder by pressing the filter reset button for ~2–3 seconds (consult your manual).

Technician Only Verify Filter Installation and Reset System

  1. Inspect the condition and correct seating of the activated carbon filter.
  2. Confirm whether the model requires filter reset via control panel or service procedure.
  3. Test the hood’s filter reminder indicator and verify C code no longer displays after reset.

Parts needed: Activated carbon filter, Filter reset button on control panel

🛑 When to Call a Pro:
  • If cleaning/replacing the filter and resetting the indicator does not clear the ‘C’ code.
  • If other symptoms (e.g., fan not working, unusual noises) accompany the error.
