Troubleshooting

DANGER: Turn off the power circuit breaker or the power switch on the junction box before performing
maintenance . Touching circuitry inside the range hood while it is energized will result in death or serious injury .
Problem
The range hood will not operate .
The range hood vibrates when the fan is operating .
The fans seem weak .
The lights work, but the fan is not spinning, is stuck, or
is rattling .
The range hood is not venting properly .
The light does not work .
Solution
- Check that the power supply cable and all electrical wiring are properly
connected .
- Check that the power is turned on at the junction box or circuit breaker.
- Check that the wiring between the switch control and the control board are
connected properly .
- Check that the range hood has been secured properly to the wall . Tighten
into position, if necessary .
- Check that the motor is secured in place . If not, then tighten the motor in
place .
- Check that the fan is not damaged . If so, replace the fan .
- Check that the duct size used is at least 6 in . (152 mm) round . The range
hood will not function efficiently with insufficient duct size.
- Check that the duct is not clogged with debris and the tight mesh on the
wall cap, if applicable, isn't restricting air flow.
- Check that the damper unit is opening properly .
- Check that no birds or animals have nested in the duct .
- 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 (after approximately 10 min.).
- Check that the fan isn't jammed or scraping the bottom .
- If nothing else works, the motor may be defective or seized . If so, replace
the motor .
- Check that no birds or animals have nested in the duct .
- Check that the distance between the cooktop and the bottom of the range
hood is between 18 in .–32 in . (458 mm–813 mm) .
- Check that duct work follows all requirements . Use round metal duct work
with a uniform diameter of 6 in . (152 mm) . The length of duct work must
not exceed 35 ft (10.7 m). Reduce the length of duct work and the number
of elbows if necessary . Ensure that all joints are properly connected, sealed,
and taped .
- Check that the duct does not open against the wind .
- Ensure that the power is on high speed for heavy cooking .
- Wind from opened windows or doors may affect the performance of the
range hood. Close all windows and doors to eliminate outside air flow.
- To enhance the performance of the range hood, open slightly a window on
the opposite side of the house where the range hood vents outdoors .
- Check to see if light bulb is burnt . If so, replace .
- Check the light bulb to see if it is loose . If so, tighten .
- Remove the problem bulb and insert one you know is working . If the
properly functioning light does not come on, the problem may be the light
assembly . Have the light assembly serviced or replaced .
