Check if the range hood has been plugged in, make •
sure that all power has been turned back ON, fused
not blown and all electrical wiring are properly con -
nected.

mine whether it is caused by defective bulbs. See
Replacing the light bulbs on Page 22-23.

erly on to the ceiling or wall. Check with your in -

over 6” hole and loosely secured.
Check if duct is clogged or if damper unit (half-cir - •
cular flapper) is not installed correctly or opening
properly. A tight mesh on a side wall cap unit might
also cause restriction to the air flow.

the bottom of the hood is within* 28” and 31” in
distance. * Due to different ceiling height configura -
tions, recommended height may not be applicable
