The best way to fix this is to take down the blades and accurately weigh them and glue on weights so they are all the same. I used small washers on mine and put them halfway along the blade. Another way is to put blades of the same weight opposite each other.
The main culprits behind a wobbly ceiling fan are usually imbalanced blades, loose screws, or a misaligned mounting bracket. Similarly, if one blade is heavier or slightly bent compared to the others, it throws off the fan's balance, causing that frustrating wobble.
The fan blade wobbling is usually a sign that the bearings on the motor that has the shaft that the fan blade is attached to turning in it are very badly worn out. Replacing the motor is usually the cost effective approach at this point in time.
Although it is normal for a fan to shake a little at high speeds, significant wobbling signals a problem. In most cases, the biggest danger of a wobbly ceiling fan is parts loosening and falling.
How much does it cost to balance a ceiling fan? Nationally, the cost to have a professional balance a ceiling fan is between $90 – $150. If you choose to balance the fan yourself, check to see if you still have the balancing kit that likely came with the original ceiling fan.
If the fan is not correctly secured to the ceiling or if the motor is not functioning as it should, then the fan can become unstable and may eventually fall. Now, you may want to know if there is anything you can do to make sure your ceiling fan is properly installed and functioning correctly.
Stand underneath the fan and look up to watch the ceiling fan blades spin. If it's in summer mode, the ceiling fan blades will be moving from right to left (counterclockwise). You'll be able to feel the coolest, most direct airflow if it's spinning the correct way.
Take a screw driver and take the screws off the canopy to expose the junction box. Here, tighten the screws joining the box to the ceiling to stop the wobbling, or replace them if they are worn out to give them a firmer grip. This should stop the wobbling and give your ceiling fan a steady rhythm.
The Givoni or Woods diagrams show a direct relationship between air speed and the drop in temperature felt by users of the room. In this case, a ceiling fan will consume between 20 and 50 watts (still a long way from the consumption of an air-conditioning system (800 to 1500 watts, i.e. 30 to 40 times more).
However, the odds of that happening are quite minimal. On average, in the United States, there are less than seven ceiling fan-related deaths reported every year. The fact is that a correctly installed ceiling fan, however wobbly, will not fall. It's secured to a strong stud via an electrical box.
Unbalanced blades can be the result of bent or warped blade arms, though sometimes the blades are unbalanced for an unknown reason. In these cases, the fan will wobble even though nothing seems to be mechanically wrong with it. This problem can typically be fixed with a fan blade balancing kit.
If it is loose, it may allow the fan to wobble. To fix it you have to take down the fan and drive some long screws into the wood support beside the box. make sure the fan is properly sitting in the notch in the ceiling support. Tighten all the screws and put lock tight on them.
One of the most frequent causes of wobbling are blades that are uneven or improperly installed. Make sure that all of the blades are tightly screwed into the blade holder and that the screws holding the blade holder to the fan flywheel are also secured. Make sure that the area is dust-free and attempt running the fan.
It's normal but not necessary. The long rod exaggerated the imbalance that can be corrected, or reduced, by properly balancing the blades. It models the wobble of Earth by the moon and the wobble of the sun by Jupiter.
