How to fix a wobbly ceilng fan
wobbly cieling fan1. make sure all mounting screws between the fan and the ceiling are tight. There is probably an electrical box mounted in the cieling that the fan is screwed into. I would turn the fan light on and then keep flipping breakers off, on at a time ,to see which breaker turns off the fan light. leave the fan light breaker off and you can unmount the fan from the cieling electrical box. The electrical box may have several holes in it for mounting screws and prehaps there are some holes left empty in the box that you can put more wood screws into to help keep the electrical box more firmly mounted and that may help lessen the wobble.Its ok to bend the electrical wiring aside to put more screws in. Just be reasonably gentle with the wiring and then bend it back somewhat to where it was before you started. make sure that wiring does not get pinched between the fan and the electrical box and that all wiring resides inside the box.#2 This is harder to do. you need to balance the blades for the fan ,similar to how a lawnmower blade is balanced after sharpening and before remounting the lawnmower blade on the mower. also kinda like balancing a car tire. I have a lawnmower blade balancing fixture that i bought at the lawnmower shop, but i dont know if there is a fan blade balancing fixture that you could buy from somewheres. Maybe try google.com,bing.com or ask.com and type into the search box fan blade balanceror fan blade balancing fixture or fan blade balancing jig.PLEASE read the directions or SPECIFICATIONS before you buy the fan blade balancer, only to find out that it only fits 9 inch diameter fan blades, and your blade is 2 4or 36 inches long.The balancer may have to fit a certain diameter hole at the centerof the fan blade. When you finally find out which side of the fan blade is heavy, you have to grind , with an electric grinding wheel, some material off the heavy side of the blade so that it is the same wieght as the light side of the blade.Try to imagine a cone shaped center[like step drills] like the capital letter V ,only up side down, so that the point is up. ON the underside of the inverted V is a needle tiped post that upside down V can pivot in any direction on. The hole in the middle of a lawnmower blade is centered somewheres on the outside of the inverted V, depending on the diameter of the hole in the lawnmower blade. The heavy side of the mower blade will go down and may touch the level asphault or the table top, depending on where you placed the balancing fixture. THen i would grind off metal until the heavy side can up to be level with the light side of the mower blade and it was considered balanced.an appliance repair parts store may sell fan balancers, but if the would fit your cieling fan, better ask before you waiste your money on something that wont work for what you want.Try calling up customer service of the manufacturor of your ceiling fan and ask about repair service for your brand fan.see what repair service has to say, im sure many others have asked them about wobbling fans.so they should have all the answers down pat.Two more thoughts.1. .MAKE SURE ALL SCREWS THAT HOLD FAN BLADES ON TO THE HUB ARE THERE AND are TIGHT. one loose fan blade mounting screw or one missing fan blade screw will unbalance the whole thing and cause wobble.2. the fan motor shaft bearing could be worn out or round or even egg shaped. If this is the cause, the motor must be diaassembled and new fan shaft bearings installed or the fan motor must be replaced. good luck and have fun!
