ADVANCED TROUBLESHOOTING
Should only be done by trained, certified service professionals
Hood insert must be out of wooden hood, down on work surface height, and power cable must be
attached with circuit breaker to this power circuit off.
Fan and Lights will not work at all at any speed or brightness, not responding to control knobs or
remote control
Checking power coming into hood power connection box: Take off wire nuts and place voltmeter
across incoming power cable. Turn on circuit breaker, see if house voltage appears (about 115 to 120
VAC). If no voltage, check your circuit breaker and wiring to range hood to find the problem.
Power is detected at hood power connection box:
Open relay board cover by removing 2 cover screws.
If power appears here:
Check for 120 volts at these points on the relay board. If power appears here , check for 120 Volts at
other end of fuse and this point. If power does not appear. fuse is blown. Turn circuit breaker off,
remove fuse, and check fuse continuity. If fuse is blown, replace with same size (5mm x 20 mm) and
value fuse. For 600 CFM motor, use 8A, for 900 CFM motor use 15A, for dual 900 CFM motor board,
use 20 Amp slow blow.
If Power is detected on relay board, but motor will not run at any speed:
check motor cable.
IF MOTOR RUNS AT ALL SPEEDS BUT ONE,
check and switch motor coil wires shown here (switch A&B, C&D). If switching does not make
missing speed work, one speed motor coil is malfunctioning. Return wires to original positions.
Replace motor.
