Bertazzoni KG Hood Light: C blinking after 120 hours for charcoal filter replacement

What Light C flashing (motor off) means

On Bertazzoni KG hoods, such as the KG30CONX and KG36CONX, light C, the second-speed light, flashes after 120 hours of use while the motor is off. This tells you the charcoal filters must be replaced on installations that recirculate the air. To reset it, press B and D together with the motor off. The owner sees the second-speed light blinking on an idle hood, and the hood still works normally.

Common causes of Light C flashing (motor off)

120 hours of use reached since the last reset
Charcoal filters saturated on a recirculating install
The reminder not reset after replacement

✓ One safe check you can try

1. Confirm the hood recirculates air rather than venting outside. 2. With the motor off, remove the old charcoal filters. 3. Fit new filters of the correct type. 4. Press B and D together to reset the alarm. 5. If light C keeps flashing, call us.

! Why to stop there

Worn charcoal filters let cooking odors and grease through.
The wrong filter type can fit poorly.
Wiring above the hood is live.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Light C flashing (motor off)Light C flashing (motor off) questions

Why is light C blinking?

After 120 hours of operation the hood asks you to replace the charcoal filters. The second-speed light blinks while the motor is off to remind you that the filters are due for replacement.

Does a hood vented outdoors need this?

No. The charcoal filter alert applies to recirculation installs only. A ducted hood only needs its mesh filters cleaned, which is the light B alert after 40 hours.

How do I reset it?

Press B and D together with the motor off, after you have fitted the new charcoal filters. The light stops blinking and the 120 hours start again.
