Do the dampers open and close freely?
With the blower housing o (see Hood Cleaning on Page 8, Section
B), locate the damper (ap) and ensure that it opens and closes freely.
If it does not, identify and remove any obstructions that are preventing
the damper from opening. Screws protruding through the duct work
are the most common obstruction. During installation, only duct tape
should be used to connect duct work to the top of the hood. Screws
that are used to connect duct work and transitions extend inside the
duct work and may obstruct the damper from opening.
Is the hood making a rubbing or scraping noise?
This may be caused by the blower wheel coming in contact with
the front edge of the blower housing or rubbing the motor mount
screws. Unsnap the suitcase latches on the blower housing (see
Hood Cleaning on Page 8, Section B) and make sure the housing
is properly seated on the face of the motor housing. If the blower
wheel is rubbing on the motor mount screws, the blower wheel will
need to be repositioned on the motor shaft (see Hood Cleaning on
Page 9, Section C).
Is the hood making a knocking or rattling noise?
This may be caused by a loose blower wheel. Remove the blower
housing (see Hood Cleaning on Page 8, Section B) and make sure
the blower wheel is properly attached to the motor shaft (see Hood
Cleaning on Page 9, Section C).
NOTE: If smoke still enters the kitchen after following these
suggestions, contact your dealer for additional service and/or
suggestions.
