TROUBLESHOOTING

Possible solution(s)

Switch off power at the service panel and lock the service
disconnecting means. If it cannot be locked, fasten a prominent
warning device. Tighten the airfoil hardware to 29 ft·lb (39.3 N·m).
If popping still occurs, verify that the airfoils are not contacting each
other. If they are, please contact Customer Service.
Verify the following:
• All wires are securely connected.
• The blue wire and the yellow wire on the controller input cable are
wired together. See the Wiring Diagrams & Electrical Guidelines
section for wiring details.
• The wall controller has power.
• Supply power is adequate and functional.
• All fuses are functional. If a fuse is blown, see the Replacing Fuses
section.
If the fan still does not start, contact Customer Service.
See the following page for fan error code descriptions and possible
solutions.
This is normal and may happen occasionally upon startup as the fan
positions itself relative to the motor stator. An initial slight jerking
forward and backward does not affect fan operation.
