Some issues can be resolved before requesting service. Review the below troubleshooting tips before contacting Customer Service for
support.
Symptom
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 is turning in the wrong direction.
The fan must be rotating counterclockwise
(when viewed from the floor) to be effective.
The variable frequency drive (VFD) generates
radio frequency (RF) noise.
VFDs 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.
The motor makes noise as fan speed increases.
Audible high frequency noise is normal during
fan operation.
Note: Some motor, gearbox, or drive noise is to be expected and is normal.

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 the popping still occurs, verify that the airfoils
are not contacting each other. If they are, contact Customer Service.
Verify the following:
• All wires are securely connected.
• The wall controller has power.
• Supply power is adequate and functional.
If the fan still does not start, contact Customer Service.
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 F/R button on the controller.
• Do not run your VFD and sensitive equipment on the same power line.
• You need to install shielded cables, run leads in grounded metallic conduit, or
use appropriate sized 4 conductor shielded cable for motor leads.
• Make sure that the motor's ground/shield lead are terminated to the VFD's
ground terminal, not the controller's ground lug.
• Ensure proper grounding at the motor, controller, and from the controller to the
power supply.
• Contact Customer Service.
This noise is present at all fan speeds and it does not change when the fan speed
is changed. If this is less than desirable, or you feel that the noise may be a result
of mechanical failure, please contact Customer Service.
