Solution
Make sure the circuit breaker and the unit's power is
ON. Use a voltage meter to check the power supply.
Check and tighten wire connection.
Check wire continuity from control panel to processor
board.
Check the power input and power output on the
motor transformer.
If it's needed, replace the motor transformer.
Replace the control panel or processor board.
Replace the motor.
Replace capacitor(s).
Replace the control panel or processing board.
Tighten the turbine impeller/squirrel cage and air
chamber.
Replace the turbine impeller/squirrel cage.
Check the installation of hood, tighten the mounting
bracket.
Try placing the trouble light bulb(s) to a working
socket, if the bulb(s) still doesn't work; replace the
halogen light bulb(s).
Check wire continuity from processor board to light
transformer to halogen light housing(s).
Check power input and power output on the light
transformer. If it's needed, replace the light
transformer.
Replace the control panel or processing board.
Adjust the clearance between the range hoods and
cook top to 27" to 30". For Island range hood, the
clearance between the range hoods and cook top is
30" to 36".
Open the window to enhance the performance of the
range hood by creating a sufficient make-up air.
Remove all obstacles from the duct work.
Change the ducting according to the manufacture
suggestion.
Check the pipe installation.
