Ceiling Fan Blade Arm Replacement Basics
Ceiling fan blade arms are replaced for many reasons. Perhaps your old blade arms are dirty, cracked or don't match your decor. Maybe you want to update the fan with new blades. It is an easy job that requires few tools but there are a few things you must keep in mind if you are going to do this project.
Step One: Things to Consider
Most home stores and retailers that sell ceiling fans also sell replacement blades. It isn't as easy as just buying a new set and installing them. You need to keep in mind the weight, width and length of your old blades and the same of the new blades your are choosing. If your new blades are too heavy or too long it will slow down the fan and cause stress on the fan motor and can actually burn the motor out. On the other hand, blades that are too small will not move are efficiently and your fan will not give you good service. To avoid these problems, you may be able to purchase new blades from the manufacturer of your fan and you should contact them to see what is available for your fan type and model number.
The popular palm leaf type ceiling fan blades are one that you really need to examine with all of these issues in mind before purchasing. Not all ceiling fans can accommodate this type of blade. Another thing to keep in mind is where the screw holes are in the bracket arms as opposed to where they are in the new blades. A good idea is to take one old blade to the store with you to make sure the holes align in the same place on the ones you may purchase. If the holes are off only a tiny amount, it will cause wobble of the fan blades and noise issues. If everything lines up, the blades are the same length, approximate weight and size, then you can install them without worry.
Step Two: Replacing the Blades
Replacing the blades is usually very easy to accomplish. Turn the fan off. If you have children who may accidentally flip the switch while you are working, then also turn off the power to the fan. Use a screwdriver to remove the screws that attach the old blades the the blade arm brackets. Do this with each blade.
Then replace each blade, one at a time, using the screws from the old blades to secure them. When all blades are installed, turn the fan on to check for wobbling.
Step Three: Correcting Wobble
There are several ways to correct a wobbling ceiling fan. If you are hearing a ticking sound that accompanies the wobble, then you have a loose screw in the fan someplace. First check all the screws you just installed and tighten them. Then check all other screws in the fan downbar and canopy.
If the fan still wobbles, gently tug or push upward each fan blade until the tips align perfectly as the fan is manually rotated. Also while you are manually rotating the fan, check the new blades to make sure they aren't warped. If warped, remove and return to the store for new ones.
