Modern Ceiling Fans With Bright Lights - You know what? The name of the article is just out and out misleading. The sole real "minus" when it comes to a ceiling fan is what it will take to get one properly installed. Ceiling fans may be difficult to install for the inexperienced do it yourselfer. In some instances, you will need to run an electrical line to the area where the ceiling fan will be installed. Hiring a competent, bonded and licensed electrician will more than likely save you a lot of grief in the future, unless you're adept at doing this sort of thing.
There's also the minor "minus" that involves the issue of periodic maintenance. Correctly installed, a ceiling fan provides years and years of nice 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 slight adjustments and get out of equilibrium. The most common culprits are loose screws that attach the blades to the motor housing, blades that are not at precisely the same angle (pitch) as the rest of the blades and a blade or blades that weigh slightly more in relation to the others. Make certain that all the screws are tight without going into great detail. If they're not tightening the ones that have come loose and run the fan. Your issue was solved when the wobbling has stopped.
If not, utilize a yardstick or other straight piece of wood and place it (together with the fan stopped) vertically in the outer edge of one of the blades. Rotate the blades by hand to be certain that each blade touches the stick. Turn the fan on again and see if you've solved the difficulty.
