Downdraft Vent Not Removing Odor or Vapor

Possible Solutions

Is the grease filter clean and installed correctly?  Is the ventilation chamber clean?

For optimal performance, operate downdraft ventilation system with the filter properly installed.  To avoid the buildup of grease, the filter should be cleaned often.

CLICK HERE for more information on cleaning the downdraft vent grille, grease filter, and ventilation chamber.

Is there air movement/draft/restriction in the room?

Any other air movement devices such as ceiling fans, air conditioner registers, etc., can create air currents which interfere with downdraft ventilation.

Turn off or limit the device creating the air currents to improve performance of the downdraft vent system.

Make-up Air:

The air that is exhausted by the unit must be replaced.  If a room or house is too "tight", the unit may not vent properly.  If a house or room is too "tight", it will be necessary to introduce more air into the environment.  Some air conditioning and heating units do allow for make-up air.

Important: Observe all governing codes and ordinances.

Adjacent Cabinets:

Cabinets that are closer than the minimum distance allowed can create dead air pockets that impair performance.  For maximum performance, the recommended distance to adjacent cabinets or walls is 6". 

Refer to Installation Instructions for complete details.

Is the control set correctly? 

Knob and Touch Pad models:

Electronic Touch Control models:

Touch 3 SPEED once for High mode, twice for Medium mode, or three times for Low mode. A beep will sound each time 3 Speed is touched.

When cooking is completed, touch OFF to turn the downdraft system off, or touch and hold 3 SPEED for approximately 4 seconds to set the downdraft ventilation system to Automatic mode. In Automatic mode, the downdraft ventilation system will shut off automatically after 10 minutes.
