TROUBLESHOOTING

PROBLEM
The fan will not start
The fan is noisy
The fan turns, but
does not move much
air
The fan wobbles
1. Check that the electricity has been turned on at the circuit breaker which had
probably been turned off during installation.
2. Turn off the electricity. Check all connections in the wiring of the fan at the
ceiling and make sure it follows the wiring instructions outlined in this manual.
1. Tighten all screws attaching blades to blade arms. Remember to tighten these
screws at least once a year because they may loosen slowly over time and
cause a clicking noise.
2. Turn off the power. Loosen the canopy and check that the wiring and/or wire nut
connectors are not resting against the canopy, possibly vibrating while the fan is
on.
3. Use of a standard light rheostat or an unapproved fan wall control to control the
fan speed will always cause an annoying "hum". Many fan motors do not work
quietly with solid state variable speed controls.
4. Check that the rubber gasket on the mounting bracket has been installed if
called for in the installation instructions.
5. Check that the canopy is not touching the ceiling.
6. Check that all screws on the motor housing and the bottom housing are tight.
Note: Always allow a day or two "run-in" time for any new fan at medium or high
speed. When attempting to diagnose noise, listen carefully from several
sides to try and isolate the location of the noise (blade, upper end, motor,
light kit, etc.)
1. The fan may be running in reverse.
2. The distance from the ceiling to the blades may be too small. For down-rod
fans, optimal placement would be 8-9 feet from the floor.
3. The room may contain items which obstruct the air flow.
4. The fan may be too small for the size of the room.
1. Make certain all blades are tightly attached to each blades' respective blade
arm.
2. Make certain that the hanger ball is locked into the hanger bracket tab by
turning the housing to see if there is any movement.
Note: A small amount of wobble is considered acceptable and should not be
considered a defect.
