Troubleshooting
Some issues can be resolved before requesting service. Review the below troubleshooting tips before contacting Customer Service for
support.
Symptom
Possible solution(s)
The fan is turning in the wrong direction.
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.
A popping noise is coming from the fan.
Airfoil noise is a result of airfoils that are
not tightened to the specified torque.
Disconnect the fan from power, and then tighten the airfoil fasteners to 29 ft·lb (39 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 at 1-877-BIG-FANS.
The fan will not start.
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 at 1-877-BIG-FANS.
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. 25).
Verify the following:
•
Do not run your controller and sensitive equipment on the same power line.
• Ensure the properly sized EM/RFI filter (p. 34) is installed.
•
Ensure proper grounding at the motor, controller, and from the controller to the utility.
If the noise is still present, contact Customer Service at 1-877-BIG-FANS.
The motor makes noise when fan speed is
increased.
Audible high frequency carrier noise may
be an indicator of a stall condition.
Verify motor currents are within limits. See the fan specifications on pages 2–3.
The fan wobbles during operation.
•
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 at 1-877-BIG-FANS.
Cutting the extension tube
CAUTION: Ensure the safety cable is undamaged after cutting and drilling the extension tube!
If your mounting structure requires a non-standard extension tube length, use the below guidelines to cut the extension tube.
Note: Use
the cut off portion of extension tube as a guide for hole placement and spacing.
