Allen And Roth Drum Ceiling Fans - You know what? The title of this article is only out and out misleading. The only actual "minus" in regards to some ceiling fan is what it requires to get one properly installed. Ceiling fans could be hard to install for the inexperienced do it yourselfer. In some cases, where the ceiling fan would be to be installed you'll need to run an electrical line to the area. Hiring a competent, bonded and licensed electrician will probably save you much grief in the long run, unless you're skillful at doing this kind of thing.
There's also the minor "disadvantage" that involves the issue of regular maintenance. Correctly installed, a ceiling fan will provide years and years of enjoyable cooling and cost-savings on your heat bill (assuming you have a fan that enables you to reverse the blade direction). Granted, you should wipe down the blades in a while but everyone has household cleaning chores to take good care of of from time to time.
On occasion, ceiling fans need slight adjustments and get out of equilibrium. The most common culprits 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 and a blade or blades that weigh slightly more compared to the others. Without going into great detail, make certain that all the screws are tight. Whenever they aren't tightening the ones that have come loose and run the fan. Your problem was solved, when the wobbling has ceased.
Otherwise, make use of a yardstick or other straight bit of wood and put it (with the fan stopped) vertically in the outer edge of one of the blades. Rotate the blades by hand to ensure that the stick touches. Turn the fan on again and see if you've solved the issue.
