Clean how to get a dog license in pa the fan blades with a damp cloth, then dry them off with a clean, dry cloth. Turn the power back on to help dry the blades and see if the fan still vibrates.
Turn the fan off again if the vibration persists. Climb up the ladder and hold a yardstick or measuring tape from the ceiling to a balnace near the high side of a blade edge. Blades are mounted at an angle, so they have a high and a low side.
Checking at the high side ensures you measure each blade at the same location. If you find one that is higher or lower than the rest, bend the blade holder up or down very slowly and very gently to bring the blade back into how to change your address with dmv colorado. Turn on the fan and check for wobble and vibration.
Turn off the fan if it ceilijg vibrates. Purchase a fan blade balancing kit, or grab a roll of duct tape and some pennies. How to balance a 5 blade ceiling fan the balancing clip from the purchased kit, or tape a penny to the top of a fan blade. Attach the clips or the penny near the outside edge of the blade.

Quality Materials: This fan is crafted from high-quality metal, gorgeous rose colored wood and durable tempered glass. Fan Blade Weight Kit; Pre-Balancing. A few things need to be done first before you balance the ceiling fan. Reminder, make sure the power is turned off at the breaker. Before you had tried all six steps above I hope you cleaned the fan, if not, start by cleaning the blades from dust and debre; as it can cause the fan to be unbalanced.
No special tools, no removing blades, no drilling, no weights and it achieves an excellent balance. This only works on free spinning, direct drive fans where the shaft can be placed horizontally at least for the balance procedure. If your fan is belt drive it should work if you can remove the belt. It works for metal blades, though it should work for plastic blades too.
With the fan UNPLUGGED and one side of the grill removed, stick a nerf dart into the cracks of the grill until it starts to touch the edge of a blade as in the picture. Spin the blades slowly with your hand and note where each blade is hitting the dart. If any blades are out of alignment, gently bend it a little at a time until it matches the other blades. On my fan one blade was about 1 centimeter out of alignment. Safety Tip: If the fan is operated by a thermostat, for example an ac condenser fan, make sure the power is turned off at the breaker because they can start at any time.
Clean the blades. Label the blades 1, 2 and 3. Use clear tape to attach a dime 'Helper Weight' to the tip of blade 2. See picture Hold blade 1 at the top center and let go and note how far blade 2 rotates down. Repeat a few times and note about where blade 2 stops each time. If it doesn't rotate, try something heavier like a penny or nickel.
If it rotates too far and swings back, try a smaller weight like a paper clip. Remove the dime from blade 2 and attach it to the tip of blade 3.
Hold blade 1 at the top center and let go and note how far blade 3 rotates. Repeat a few times, noting where blade 3 stops. Repeat this process to compare all the blades until you are able to rank the blades from heaviest to lightest. Now you will adjust the lightest blade until it is equal to the heaviest blade. Start out by lightly sticking a 6" piece of matching color duct tape on the center of the lightest blade.
Using the comparison method in step 2, compare the lightest blade to the heaviest blade, adjusting the length of tape on the lightest blade until the distance both blades travel during the test are equal which indicates they are balanced. Repeat this method to adjust the weight of the middle blade to equal the heaviest blade. After the weight of the lighter blades have been adjusted, tape the dime to each blade in turn and note how far it rotates, the stop points should be close for each test.
You can see the duct tape on 2 blades in the picture, the lightest blade has about 5" and the middle blade about 4".
Four Blades? Try taping the dime to each blade in turn and release from the 3 o'clock position. Measure how far each blade rotates, ranking them heaviest to lightest.
Start adding tape to the lightest blade first and keep retesting until they all rotate the same distance. If your fan allows the blades to be moved up and down the shaft, move them as far from the motor as possible. My fan was tested with the blades close to the motor as in picture 1, and as far from the motor as possible as in picture 2. Having the blades far from the motor made a large decrease in vibration.
With my Air King I was able to flip the blade assembly over to get the blades an extra 2 centimeters away from the motor. Note in picture 2 the set screw collar is not visible because the blades have been flipped around. Flipping the blade assembly over is not recommended on curved fan blades designed to spin in one direction, they will be inefficient.
My Air King 20" Whole House Fan which is a fantastic fan had irritating vibrations on high speed, this balancing method made a huge difference.
I tried 3 other methods before coming up with this method, they were more difficult and didn't work as well. I took the fan off the motor shaft, mounted it on a shaft sized drill bit which was then propped up between two level chairs. It was then balanced by comparing the blades 2 at a time and adding tape to the lighter blades similar to the method above. The balance was not quite as good and this method was a pain. I took the fan off the motor and hung it from a table, just above the floor, by a rope going through the center hole.
As the rope was raised and lowered off the floor the light blades were noted and adjusted. This method was also a pain and the resulting balance was poor. A vibration sensing app 'VibSensor' was used on an android phone to measure the vibrations.
A piece of duct tape was attached to each blade in turn and then the fan was run so the vibration intensity could be noted.
The app was great but adding the right amount of tape was a guessing game. Hours were wasted. Thank you! This improved my fan a lot. Very intuitive!
I think "flipping" the blade may not be a good idea for fans that are not designed to be reversible. Mine that has cupped blade sections only works well with the blade not flipped. Reply 1 year ago. Good point. I added "Flipping the blade assembly over is not recommended on curved fan blades designed to spin in one direction, they will be inefficient.
