This can also happen if the blade itself is out of balance. Try removing the blade and running the fan motor without the blade to see if the motor shaft wobbles when running. If it does, the motor shaft may be bent. If it does not, the blade may be out of balance.
The fan blade arms can be easily bent out of shape by a forceful contact with the fan while it was spinning. The solution is to make sure each fan blade matches the others, both in angle, spacing, and elevation of the blade. If one fan paddle arms is deformed, they can be gently bent back into shape by hand.
Most fans come with a balancing kit. This consists of a little plastic clip on weight and a couple of stick on metal bits. The idea is to slip the plastic weight to the end of a fan blade and try the fan. It could be better or worse. Continue around each of the blades until the thing runs smoothly.
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.
Misaligned Blades
Blade misalignment means one or more of your blades are spinning at a different height than the other. The draft from the misalignment of blades distorts the airflow and wobbles the blades. Prolonged misalignment can cause the blade screws to loosen and the blade holders to warp.
A wobbly fan can be irritating, noisy, and even a safety hazard. If your ceiling fan is wobbling, you don't want to put off finding a solution – it's best to fix the problem as soon as possible.
Wobbling will not cause the fan to fall, and there have been no such reports. Wobbling can, however, cause light fixture covers or shades to loosen and potentially fall. These items should be securely attached, with all screws tightly set in place.
Wobbling and Shaking
A tower fan vibrating while running often indicates an issue with the fan blades. Check for these common causes: Unbalanced Blades - If dust or debris accumulates unevenly on the blades, it can create an unbalanced rotation resulting in wobbling.
This can also happen if the blade itself is out of balance. Try removing the blade and running the fan motor without the blade to see if the motor shaft wobbles when running. If it does, the motor shaft may be bent. If it does not, the blade may be out of balance.
It is possible that there may be some accumulation of debris inside of the fan on the blade or blade shaft which is causing the excessive vibration. It is important to not that slight vibration is completely normal on a tower fan.
Try new blades.
If the fan blades are warped or sagging, you can try to (carefully) bend them back into shape, but the simplest solution might be to just buy a new set of blades. Swap them out all at once and your ceiling fan should be good to go.
The rotation of a fan is based on the principles of electromagnetism. When an electric current is passed through the fan's motor, it creates a magnetic field that interacts with the fan's rotor. This interaction causes the rotor to rotate, which in turn causes the fan's blades to spin and generate a flow of air.
If the motor hums but doesn't run, and if it's hard to turn, its because the bearings are seized. If it hums and turns freely but doesn't run, then it's probably the capacitor connected to the motor, and if it doesn't even hum, it's the motor's thermal fuse, switch, or power cord.
Yes, if a ceiling fan is starting to wobble then there are high chances of falling it down. If a ceiling fan has started to wobble, then there could be some reasons behind it.
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.
The chances of a properly installed and maintained ceiling fan falling are extremely low. Most fans are designed with safety mechanisms that ensure the blades and motor stay attached to the ceiling.
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.
If a single blade on the fan is warped or damaged, it can cause the entire fan to wobble as it rotates. While these wobbles might be tiny in the scheme of things, over time they can cause serious damage to the machinery designed to rotate the fan.
