Ceiling Fan Light Bulb Socket Size - Do you know what? The name of this article is simply out and out misleading. The only actual "minus" when it comes to your ceiling fan is what it takes to get one properly installed. Ceiling fans can be difficult to install for the inexperienced do it yourselfer. Sometimes, you will need to run an electrical line to the place where the ceiling fan will be to be set up. Unless you are skillful at doing this sort of thing, hiring a licensed, bonded and qualified electrician will more than likely save you a lot of grief in the long term.
There is also the minor "minus" that entails the problem of periodic care. Properly installed, a ceiling fan will provide years and years of enjoyable cooling and cost-savings in your heating bill (assuming there is a fan that allows one to reverse the blade direction).
On occasion, ceiling fans require slight alterations and get out of equilibrium. The most common offenders are loose screws that attach the blades to the motor casing, blades that are not at the same angle (pitch) as the rest of the blades as well as a blade or blades that weigh somewhat more in relation to the others. Be certain that all of the screws are tight, without going into great detail. Whenever they're not tightening the ones that have come loose and run the fan. Your problem was solved, when the wobbling has stopped.
Otherwise, use a yardstick or other straight bit of wood and place it (with the fan quit) vertically in the outer edge of one of the blades. Rotate the blades by hand to be certain that the stick touches. If one or more do not, merely (and gently) bend the blade(s) so that their pitch matches the others and repeat the process until you are satisfied that each blade has the same pitch.
