TROUBLESHOOTING

Possible Solution
• Verify that the fan's circuit breaker has power and that it is on.
• Verify that the VFD's receptacle has power and that the VFD is plugged in.
• Check for secured plug connections. Each connection should be checked to
ensure they are fully engaged.
• Inspect for loose wiring connections. Each termination should be checked to be
sure they are firmly tightened.
• Cycle the power to the VFD by flipping the circuit breaker off for a minimum of
three minutes. Flip the circuit breaker back on and check the fan's operation.
• Make sure the VFD voltage is a match for the supply voltage.
• Make sure that correctly sized fan blades have been installed.
• Check for correct fan blade installation. Be sure that all blades are the same size
and that all blades have been properly installed and tightened.
• Ensure all guy wires are tensioned properly and that the downrod is plumb.
• Check for improper incoming air discharge. Make sure that no discharge is
blowing directly on the fan.
• Make sure that the 'sagging' blade has been properly tightened.
