General Troubleshooting
The Fan Turning in the Wrong Direction
The fan must be rotating counter-clockwise (when viewed from the floor) to be effective. If the fan is not rotating in this direction, press
the “FWD/REV” button on the wall control.
Popping Noise Is Coming From the Fan
Airfoil popping comes from airfoils that are not tightened to the specified torque (see torque chart on p. 6).
• Switch off power at service panel and lock service disconnecting means. (If it cannot be locked, fasten a prominent warning
device.) Tighten airfoil fasteners to specified torque. If popping still occurs, verify that the airfoils are not contacting each other. If
the airfoils are contacting each other, contact Big Ass Fans Customer Service at 1-877-BIG-FANS.
The Fan Is Not Starting
• Make sure that all wires are securely connected.
• Make sure the wall control is set to “RUN” and PU mode.
• Verify that supply power is adequate and functional.
• Contact Customer Service at 1-877-BIG-FANS.
The Fan Controller Generates Radio Frequency (RF) Noise
Fan controllers generate radio frequency noise in many ways, but this noise can be prevented by using the proper wiring practices
outlined in the “Electrical Installation” section (p. 24).
• Do not run your controller and sensitive equipment on the same power line.
• Install properly sized EM/RFI filter (see pp. 29, 31).
• Ensure proper grounding at the motor, controller, and from the controller to the utility.
• 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 per fan specifications
on pages 2-3.
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.
WARNING: Before servicing or cleaning unit, switch power off at the service panel and lock the service
disconnecting means to prevent power from being switched on accidentally. When the service disconnecting
means cannot be locked, securely fasten a prominent warning device (such as a tag) to the service panel.
WARNING: When service or replacement of a component in the fan requires the removal or disconnection of a
safety device, the safety device is to be reinstalled or remounted as previously installed.
