Ceiling Fan Speed Control Module - Do you know what? The name of this article is just out and out misleading. The sole real "minus" in regards to some ceiling fan is what it takes to get one correctly installed. Ceiling fans could be difficult to install for the inexperienced do-it-yourselfer. In some cases, you will need to run an electrical line to the region where the ceiling fan is to be set up. Unless you're adept at achieving this sort of thing, hiring a capable, bonded and licensed electrician will most likely save you a lot of grief in the future.
There's also the minor "minus" that entails the problem of periodic maintenance. Properly installed, a ceiling fan will give you many, many years of enjoyable cooling and cost-savings on your own heat bill (assuming you've got a fan that enables one to reverse the blade direction).
On occasion, ceiling fans need minor alterations and get out of equilibrium. The most typical culprits are loose screws that attach the blades to the motor casing, blades which aren't at precisely the same angle (pitch) as the rest of the blades and a blade or blades that weigh somewhat more compared to the others. Make sure that all of the screws are tight without going into great detail. Whenever they truly aren't tightening the ones that have come loose and run the fan. Your problem continues to be solved, when the wobbling has quit.
If not, utilize a yardstick or another straight piece of wood and put it (with the fan stopped) vertically in the outer edge of among the blades. Rotate the blades by hand to be certain that the stick touches. If one or more do not, just (and gently) bend the blade(s) so that their pitch matches the others and repeat the procedure until you're satisfied that each blade has the same pitch.
