1. If the range hood does not operate after installation:
• Check if the range hood has been plugged in, make sure that all power has been turned back
on and all electrical wirings are properly connected.
• Swap out light assembly to working ones to determine whether it is caused by defective bulbs.
(See Replacing the LED light bulb, page 12)
2. The range hood vibrates when the blower is on:
• The range hood might not have been secured properly onto the ceiling.
3. The blowers seems weak:
• Check that the duct size used is at least 6” (15.2cm). Range hood WILL NOT function efficiently
with insufficient duct size.
• Check if duct is clogged or if damper unit is not 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 bottom due to shipping damage.
5. The hood is not venting out properly:
• Make sure the distance between the cook top and the bottom of the hood is within 28” (71 cm)
and 31” (78.7 cm) range.
• 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.
