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.

• 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 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

page8.
