General troubleshooting

WARNING: Risk of fire, electric shock, or injury to persons during cleaning and user-maintenance! Disconnect the
appliance from the power supply before servicing.
Some issues can be resolved before requesting service. Review the below troubleshooting tips before contacting Customer Service for
support.
Symptom
The fan is turning in the wrong direction.
A popping noise is coming from the fan.
Airfoil noise is a result of airfoils that are
not tightened to the specified torque.
The fan will not start.
The fan controller generates radio
frequency noise (RF).
Fan controllers generate RF noise in many
ways, but this can be prevented using
the proper wiring practices outlined in
"Electrical Installation" (p. 26).
The motor makes noise when fan speed is
increased.
Audible high frequency carrier noise may
be an indicator of a stall condition.
The fan wobbles during operation.
Note: Some motor, gearbox, or drive noise is to be expected and is normal.

Troubleshooting

Possible solution(s)
To be effective, the fan should be rotating in the counterclockwise direction (when
viewed from the floor). If the fan is not rotating in the counterclockwise direction, press
the FWD/REV button on the wall controller.
Disconnect the fan from power, and then torque the airfoil hardware to 29 ft·lb
(39.3 N·m). If the popping still occurs, verify that the airfoils are not contacting each
other. If they are, contact Big Ass Fans Customer Service.
Verify the following:
• Make sure that all wires are securely connected.
• Make sure the wall controller is set to RUN and LOC mode.
• Verify that supply power is adequate and functional.
If the fan still does not start, contact Customer Service.
Verify the following:
• Do not run your controller and sensitive equipment on the same power line.
• Ensure proper grounding at the motor, controller, and from the controller to the utility.
If the noise is still present, contact Customer Service.
Verify motor currents are within limits. See the fan specifications on pages 2–3.
• Verify that the mounting structure is rigid enough to support the fan and that the fan is
not being exposed to external air forces.
• If guy wires were installed, confirm proper installation. If guy wires were not installed,
contact Big Ass Fans Customer Service.
