TROUBLESHOOTING
Possible solution
• Verify that the fan's circuit breaker has power and that it is on.
• Does the VFD's receptacle have power and is the VFD 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 3 minutes. Flip the circuit breaker back on and
check the fan's operation.
• Make sure the motor 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 downrod hardware has been tightened to 65 ft lbs. 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.
