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 hood behind/above blowers - do they move/open freely?
• Check the dampers/vents to outside - do they open freely, with no obstructions?
• Check for damaged or obstructed ductwork.
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 page8.
2. Use a ¼” nut driver to remove the three motor
mount screws that attach the motor to the base.
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
page8.
