Will a smaller blade on a ceiling fan cause problems
Interesting situation.. not many people want to down-size a fan. Anyway, reducing the size of the fan blade shouldn't cause a problem - as long as the pitch or angle of the blade remains the same or is less than the original. Increasing the angle with a smaller blade could actually move MORE air than what the motor was designed to do - resulting in overloading and shortening the motor's life in the best case scenario. Worst case scenario - well, anything for electric devices in a worst case scenario usually involves fire, burns and even death (though not likely to happen).
Prior to starting, make sure all the blades are the same in every way including: length, width, angle and weight. A warped blade can cause wobble, too. Stand on a ladder and spin the fan by hand. Look for a blade that is tipped up or hangs lower than the others. Make adjustments as needed to correct (it may not be possible to correct a warped blade - so be forewarned). If any of the variables listed in the first sentence of this paragraph are different from those of the other blades, wobble and motor noise will result. Neither condition should be allowed to exist longer than absolutely necessary. You can minimize these effects by operating the fan at a slower speed. Generally, the blades should be pretty close in all of these variables - but a wobbly fan indicates an imbalance. Weights placed on fan blades can help correct wobble - but can be tricky to determine which blade is the cause.
