Ceiling Fan Pull Chain Stuck - You know what? The title of the article is merely out-and-out misleading. The sole real "con" in regards to a ceiling fan is what it takes to get one correctly 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 installed, you'll need to run an electrical line to the location. 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 is also the minor "disadvantage" that involves the problem of periodic care. Correctly installed, a ceiling fan will give you years and years of pleasant cooling and cost-savings on your own heating bill (assuming you have a fan that allows one to reverse the blade direction).
On occasion, ceiling fans need minor adjustments and get out of equilibrium. The most often encountered offenders are loose screws that attach the blades to the motor housing, blades that aren't at exactly the same angle (pitch) as the remaining 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're not tightening the ones that run the fan and have come loose. When the wobbling has stopped, your issue was solved.
Otherwise, utilize a yardstick or other straight bit of wood and put it (with the fan quit) vertically at the outer edge of one of the blades. Rotate the blades by hand to be certain that each blade touches the stick.
