My fan will not start.
Make sure all wires are securely connected and that supply power is adequate and functional. If the fan still does not start, contact Customer Service.
Trouble with Something Else
A popping noise is coming from my fan.
Airfoil noise occurs when airfoils are not tightened to the specified torque. Disconnect the fan from power, and then tighten the airfoil hardware to 29 ft·lb (39.3 N·m). Note: If the hardware is stainless steel, tighten the airfoil hardware to 10 ft·lb (13.6 N·m). If popping still occurs, verify that the airfoils are not contacting each other. If they are, contact Customer Service.
My 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 Customer Service.
The keypad is showing “F_EF” or some other code.
This is most likely a fault code. Big Ass Fans have built-in checks that look for both internal and external faults.
If your keypad reads “F_EF,” this means that the fire alarm has gone off while the fan was connected to your fire panel.
Regardless of the fault code, press the red “Stop” button to clear it. View the full list of fault codes.
My fan’s VFD generates radio frequency (RF) noise.
VFDs generate RF noise in many ways, but this can be prevented using proper wiring practices.
- Do not run your fan and sensitive equipment on the same power line.
- Ensure proper grounding at the motor, at the VFD, and from the VFD to the utility.
If noise is still present, contact Customer Service.
My fan’s motor makes noise when the speed is increased.
- Audible high-frequency carrier noise may be an indicator of a stall condition.
- Some motor, gearbox, or VFD noise is to be expected and is normal.
