TROUBLESHOOTING

Troubleshoot your problem by using the chart below. If the appliance still does not
work properly, contact W Appliance Co. customer service center. Customers must
never troubleshoot internal components.
TROUBLE
Fan will not start
Fan sounds noisy
POSSIBLE REMEDY
A. Check all fuses or circuit breakers. Replace if missing.
B. Turn off electrical power and check all wire connections to
fan and in switch housing.
A. Use of standard light rheostat or continuously variable fan
speed wall control will always cause harmonic distortions, or
a humming noise. Many fan motors do not work quietly with
solid state variable controls. If a quiet wall control in desired,
use only 3-speed UL approved wall controls.
B. Always allow a few days "break in" time for any new fan at
medium or high speed. Try to diagnose the exact location of
the noise by listening carefully from several sides (Besides,
Motor, Light kit, etc.). Fan noise can come from a light kit.
C. Make sure all screws in the fan assembly and light kit are
tight and properly threaded. If not, back out and retighten.
Tighten the screws at least once a year because they may
loosen slowly over time and cause a clicking noise.
D. Make sure the light kit is securely fastened to the fan, and all
glass screws are finger tightened only. Do not tighten with
pliers or a screw driver.
E. Make sure mounting bracket is installed snugly to junction
box.
F. Make sure wire nuts in switch housing or canopy are not
tatting against each other or against wall of housing. Wrap
with electrical tape if necessary.
G. Make sure the canopy is not touching the ceiling.
H. Assure that the screws fastening blade holders to motor are
tight and the lock washers provided for that purpose have
been used.
I. Make sure all light bulbs are fully screwed in.
