Troubleshooting Tips
WARNING: Please turn off the power circuit or power breaker panel before troubleshooting this range hood. Failure to do
so can cause death or serious injury.
Problem Solution
My range hood won’t work. 1. Make sure the power supply and wiring are connected
securely.
2. Double-check to see that the power breaker is on and
the power supply is live.
3. Check to see that the control panel cables are connect-
ed correctly to the switchboards.
My range hood vibrates while the fan is operating. 1. Check to ensure the hood is firmly secured to the
cabinet/wall. Tighten or add screws if necessary.
2. Confirm that the motor is firmly in place and secured
safely. If it is not, tighten it.
3. If those steps haven’t resolved the issue, your fan may
be damaged. If it is damaged, you may need to replace it.
The fan is operating weakly. 1. Double-check to ensure the duct size is correct.
2. Clean ducts or filters if they’re dirty. Also, check to make
sure the mesh enclosure on the hood is receiving proper
air ventilation.
3. If possible, check to see that the damper is functioning
properly regarding the opening.
The light is not working. 1. Check to see if lightbulb is loose and needs to be
tightened.
2. If tightening doesn’t fix the problem, replace bulb with a
new one and see if that solves the issue.
3. If replacement and/or tightening does not solve, you
may need to replace the lighting service system on the
hood.

The vent hood is not working efficiently. 1. The minimum distance between the cooking area and
the appliance should be 24" or 30" maximum. Check to
see if this is correct.
2. Make sure that the duct is not susceptible to easy wind
opening.
3. Make sure the fan speed is at the appropriate rate. The
heavier the cooking, the greater the speed of the hood
should be set.
4. Closing the windows and doors in the room will allow
the vent to work much better.
5. As noted during the installation process, all ductwork
must be done correctly. You may need to reduce the
length of ductwork or reduce elbows.
6. Make sure all joinery in ductwork is sealed and secured
properly.
The fan is not working properly even though the lights are
working.
1. Double-check that the fan is not jammed /that it isn’t
scraping any of the surfaces of the hood.
2. If this doesn’t work, you may need to replace the motor
as it may be defective.
