1. If the range hood does not operate after installation:
- Check if all power has been turned back on and all electrical wiring
is properly connected.
- Check that the power connection for the unit is properly connected.
- Make sure the wiring between the switch board and control board
are connected properly.
2. The range hood vibrates when the blower is on:
- The range hood might not have been secured properly to the wall.
- Check if the motor is secured in place. If not, then tighten the motor
in place.
- Check if there is a damaged blower wheel. If so, change the blower
wheel.
3. The blowers seems weak:
- Check that the duct size used is at least 15.2 cm (6 in.). 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 restrict air flow.
4. The lights work but the blower is not spinning, is stuck or is
rattling:
- The blower might be jammed or scraping the bottom.
- The motor is defective, possibly seized - change the motor.
- The thermal protection system detects if the motor is too hot to
operate and shuts the motor down. In this case the motor will
function properly after the thermal protection system cools down
(approx. 20 min.).
5. The hood is not venting properly:
- Make sure the distance between the cook top and the bottom of
the hood is between 46 cm (18 in) for electric ranges and 75 cm
(29.5 in) for gas ranges.
- 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.
- Wind from opened windows or doors in the surrounding area are
affecting the ventilation of the hood. Close all windows and doors
to eliminate the outside air flow.
- Check if the direction of duct opening is against the wind. If so,
20
adjust the direction of the duct opening.
- Check if the wrong size of ducts are being used.
