Troubleshooting
1. If the range hood or LED light does not operate  •
after installation: 
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. 
Swap out light assembly to working ones to deter- 
mine whether it is caused by defective bulbs. See 
Replacing the light bulbs on Page 22. 
2. The range hood vibrates when the blower is on: • The range hood might not have been secured prop- 
erly on to the ceiling or wall.
3. The blower or fan seems weak: • Check that the duct sized used is at least 6” or 3-1/4
x 10”.  Range hood WILL NOT function efficiently
with  insufficient  duct  size.  For  example:  7”  duct
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.
4. The lights work but the blower is not spinning at all,  •
is stuck or is rattling.
The blower might be jammed or scraping the bot- 
tom due to shipping damage. Please contact us im- 
mediately. 
5. The hood is not venting out properly: • Make sure the distance between the stove top and
the  bottom  of  the  hood  is  within  24”  and  30”  in
distance; with minimum 30” for gas stove top.
• Reduce the  number  of  elbows  and length  of duct
work.  Check  if  all  joints  are  properly  connected,
sealed, and taped.
• Make  sure  the  power  is  on  high  speed  for  heavy
cooking.
