This page contains a list of areas which have been known to cause sound problems in fans. Every one of these are based on actual cases we have seen. So don't automatically rule them out since one of them may be the cause of your problem. Blade Iron Motor Screws: Take a moment to loosen and retighten all screws holding the blade irons to the motor. These can loosen over time. A cross-threaded screw at the time of installation can cause sound too as the blade iron shifts during operation. High Gloss Blades: High gloss blades will often make clicking noises when they shift due to the screw heads gouging into the lacquer, or the blade rubbing against the blade iron. Use of felt or rubber washers between the screw head and the blade can minimize the sound, and use of a lubricant such as WD-40 on the blade surface where the blade comes in contact with the arm can reduce sound. Or buy a set of nongloss blades if they are available for your specific fan. Blade Iron Blade Screws: Take the blades off the fan and check the screws holding the blade to the blade iron. These can loosen after periods of use. The screws should be tight. Ceiling Mount: Take down the canopy and check the mounting bar. Make sure the mounting bar is firm and tight to the outlet box in the ceiling. On most fans which hang from a pipe, if the ceiling bracket is in contact with plaster or sheetrock a clicking noise may be caused as the bracket gouges into the sheetrock. Downrod: Make sure the downrod is tight at the connection with the motor and at the connection near the ceiling. A loose downrod set screw can cause the downrod to shift during operation causing a sound. Pull Chains: As the motor runs it may cause the pull chain to swing and make contact with the fan, the fan light or the fan glass. Reposition the light or the glass so the chain does not come in contact with them. Flywheels: Some higher quality fans use a part which is called a flywheel. The flywheel is a rubber wheel which the fan blade arms are mounted to. This flywheel is in turn attached to the motor shaft by a single screw. Occasionally on older fans the screw on the flywheel can loosen causing the flywheel to drop of the motor shaft and create a clicking or scraping noise. If your fan has a flywheel check the space under the to ensure they flywheel is not coming in contact with the parts below it. If it is you may need to raise the flywheel back onto the motor shaft. Ocassionaly the rubber on the flywheel may become brittle. If the rubber on the flywheel is torn you may need to replace the flywheel. Housing clearance: Check the space between the inner fan motor and the outer decorative fan housing. In some cases sounds may be caused as the motor comes in contact with a portion of the outer housing. If you find an area which is coming in contact you usually can reposition the decorative housing to increase the space between the housing and the motor. Objects in Room: As silly as it may sound, people who have complained of ticking sounds in the motor have had repair people out to their home only to find out the wind of the fan was causing a curtain string or other object within the room to make a sound. Some have even noted a clicking noise in the fan even though the fan is not on! Make sure to rule out the obvious first before assuming the worse. |
