Ceiling Fan Light Adapter - You know what? The name of this informative article is simply out and out misleading. The only actual "minus" in regards to a ceiling fan is what it will take to get one properly installed. Ceiling fans may be hard to install for the inexperienced do it yourselfer. In some cases, where the ceiling fan would be to be set up, you'll need to run an electric line to the location. Hiring a qualified, bonded and licensed electrician will most likely save you much grief in the long term, unless you are skillful at achieving this type of thing.
There's also the minor "minus" that involves the issue of regular maintenance. Correctly installed, a ceiling fan will provide years and years of pleasant cooling and cost-savings on your heat bill (assuming you've got a fan that enables one to reverse the blade direction). Allowed, you should wipe down the blades once in a while but everyone has household cleaning chores to take good care of of from time to time.
On occasion, ceiling fans need minor adjustments and get out of balance. The most common offenders are loose screws that attach the blades to the motor housing, blades that aren't at the same angle (pitch) as the rest of the blades and a blade or blades that weigh somewhat more compared to the others. Without going into great detail, make sure that all the screws are tight. If they aren't tightening the ones that have come loose and run the fan. Your issue was solved, in the event the wobbling has stopped.
If not, make use of a yardstick or another 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 each blade touches the stick. If one or more do not, simply (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. Turn the fan on again and see in the event you've solved the problem.
