MOTOR REPLACEMENT MOTOR REPLACEMENT
MOTOR IDENTIFICATION AND POSITIONING MOTOR IDENTIFICATION AND POSITIONING
Motors are color-coded; black and white motors have different rotations and must be installed in
the correct positions.
• Housings with a single blower use a white blower and wheel.
• Housings with two blowers use a white blower on the right and black on the left.
Make sure you have the correct motor in each housing position.
• If the replacement blower motor includes a blower wheel, then you can remove the motor and
wheel together. If you will re-use your existing wheel, then you may wish to remove the wheel
before removing the motor.
1. Remove the shield and blower housing as described in
"BLOWER WHEEL REMOVAL" on page 8.
2. Use a ¼" nut driver to remove the three motor mount
screws that attach the motor to the hood.
3. Gently pull the motor forward and down.
4. Disconnect the wiring harness, remove the old motor.
• To avoid damage to the blower wheel, you may wish to
install the motor and then install the wheel onto the motor.
5. Lift the new motor so you can connect the wiring
harness. Be sure to fully engage the electrical
connections and tighten the motor mount screws.
6. Check the blower wheel clearance and adjust
as needed, as described in "BLOWER WHEEL
INSTALLATION" on page 8.

TROUBLESHOOTING

If the hood does not perform satisfactorily, check the following:
• Do the blowers run?
• Are the blower wheels installed on the correct motors? (black wheel on black motor, white
wheel on white motor)
• Are the motor and wheel assemblies installed in the correct locations?
• Check the damper doors in blower housing(s) - do they move/open freely?
• Check the dampers/vents to outside - do they open freely, with no obstructions?
• Check for damaged or obstructed ductwork.
To reduce the risk of personal injury, turn off power to the hood at the
breaker or the circuit disconnect before attempting to remove the
blower motor.
