Some of the fan blades on several fans are drooping how to fix? lost light in 2 of them?

You don't specify what brand and model of fan. However, I can tell you that it is a common problem - especially among older models. A while back I talked with a Hunter service guy and his answer was this: There can be several causes, including some loose piece of insulation or other FOD (foreign object damage) inside the motor. However, the most common cause is that the bearings get worn (for which he said there was no "official" cure or repair kit).

I have had some success balancing the blades. [Dynamic balance by attaching small weights (coins or washers) - or removing the blades and doing a static balance. Dynamic balancing is better. Make sure any weights are WELL attached, since at high fan speeds they become serious projectiles.] Note that this will help, but the problem will come back.

Bottom line, the mfr wants you to buy a new fan. Replacing the motor with an old motor frequently doesn't help - because it has the same problem. Some older, and very expensive fans, have lifetime warranties and will replace the motor. However, I discovered that many times they define "lifetime" as the life of the fan, not the owner. If they product is no longer sold, then it's past the lifetime.

Last thing: Make sure it really *is* the fan making the noise. If the blades are unbalanced, then the fan may be rocking slightly on it's hang-point (where it is attached to the ceiling) and that may be making the noise.

wobbly cieling fan
1. make sure all mounting screws between the fan and the ceiling are tight. There is probably an electrical box mounted in the cieling that the fan is screwed into. I would turn the fan light on and then keep flipping breakers off, on at a time ,to see which breaker turns off the fan light. leave the fan light breaker off and you can unmount the fan from the cieling electrical box. The electrical box may have several holes in it for mounting screws and prehaps there are some holes left empty in the box that you can put more wood screws into to help keep the electrical box more firmly mounted and that may help lessen the wobble.
Its ok to bend the electrical wiring aside to put more screws in. Just be reasonably gentle with the wiring and then bend it back somewhat to where it was before you started. make sure that wiring does not get pinched between the fan and the electrical box and that all wiring resides inside the box.
#2 This is harder to do. you need to balance the blades for the fan ,similar to how a lawnmower blade is balanced after sharpening and before remounting the lawnmower blade on the mower. also kinda like balancing a car tire. I have a lawnmower blade balancing fixture that i bought at the lawnmower shop, but i dont know if there is a fan blade balancing fixture that you could buy from somewheres. Maybe try google.com,bing.com or ask.com and type into the search box fan blade balancer
or fan blade balancing fixture or fan blade balancing jig.
PLEASE read the directions or SPECIFICATIONS before you buy the fan blade balancer, only to find out that it only fits 9 inch diameter fan blades, and your blade is 2 4or 36 inches long.
The balancer may have to fit a certain diameter hole at the center
of the fan blade. When you finally find out which side of the fan blade is heavy, you have to grind , with an electric grinding wheel, some material off the heavy side of the blade so that it is the same wieght as the light side of the blade.
Try to imagine a cone shaped center[like step drills] like the capital letter V ,only up side down, so that the point is up. ON the underside of the inverted V is a needle tiped post that upside down V can pivot in any direction on. The hole in the middle of a lawnmower blade is centered somewheres on the outside of the inverted V, depending on the diameter of the hole in the lawnmower blade. The heavy side of the mower blade will go down and may touch the level asphault or the table top, depending on where you placed the balancing fixture. THen i would grind off metal until the heavy side can up to be level with the light side of the mower blade and it was considered balanced.
an appliance repair parts store may sell fan balancers, but if the would fit your cieling fan, better ask before you waiste your money on something that wont work for what you want.

Try calling up customer service of the manufacturor of your ceiling fan and ask about repair service for your brand fan.
see what repair service has to say, im sure many others have asked them about wobbling fans.
so they should have all the answers down pat.
Two more thoughts.
1.
.MAKE SURE ALL SCREWS THAT HOLD FAN BLADES ON TO THE HUB ARE THERE AND are TIGHT. one loose fan blade mounting screw or one missing fan blade screw will unbalance the whole thing and cause wobble.
2. the fan motor shaft bearing could be worn out or round or even egg shaped. If this is the cause, the motor must be diaassembled and new fan shaft bearings installed or the fan motor must be replaced.

good luck and have fun!

Remove one of the screw from a fan blade and take it to a hardware store. Tell them you need some to replace the lost ones for your ceiling fan blades.

Several things besides lack of lubrication can cause the problem.

One or more of the fan blade irons may be loose. As well as the wooden blade itself. In both cases a Phillips screw driver will solve the problem.

The pull chains are clicking against the the fan. I've see this happen many times. Simply putting some tape around the chain, where it touches the fan, will generally silence it.

And last, but not least ... The fans may be out of balance. But, this may be due to loose screws in the fan blade irons.

As far as lubrication is concerned. Older unit (10 to 15 years) have sealed motors that were to be permanently lubricated. Even some of today's brands and models are too. At best, if none of the above silenced the ticking, is to use a little WD40 with a straw nozzle up into the fan housing. Be careful doing this as the WD40 may drip. Be sure the wall switch for each fan is OFF, before attempting this.

Hope this helps you and thanks for choosing FixYa.

If you plug it in and turn it on, does it "humm".
If so, it is getting power. It could be the blades are stuck on something: do they turn by hand?
The motor could be dirty also, is the blade hard to turn?
It can be repaired by Vornado, or you can dis-assemble the motor and clean it.

can notify hampton bay costumer service 1-877-527-0313 home depot-lowes -online stores or lighting/fan stores anyof these places carry replacement fan blades

Try reversing the mounting of each blade so that the droop is upward. These blades should be made of wood which do not ordinarily warp in this fashion. Try the above to see if they will tend to straighten out over some period of time. You might also try running a 'heat gun' over the top of the blades (don't allow the gun to remain in one place or it will scorch the blade finish) after doing the above to accelerate the blade straightening. Blade replacement is a last resort. Hope this helps!

put a piece of masking tape on each blade and number them.while you're up there check that mounting screws are tight.switch position of blades,i.e. move #1to #3,see if it's better or worse;switch #2 & #4 or#4 &#6 etc. until you find the combination giving you the best 'balance'

hi! there,
there are two type of removing the blade of electric fan,one is there is a center knob with mark arrow loosen and tight direction at the center holding fan blade, this to lock fan blade on its shafting. to remove fan blade.loosen holder knob on clockwise direction while holding the fan blade,to release the knob check the arrow on the knob. after loosening knob pull out blade from the shafting.

the other type the fan blade has lock in bolt at the back side of the fan blade bolt in on the shafting of the fan, you need here a tools such as set of socket wrench small one to loosen the bolt
after loosening lock in bolt, pull out fan blade.

besure doing this tha electic fan was unplug to elecrtic source. have a nice day.just rate me,thank's

When our 2-year-old niece got hold of our Hampton Bay fan remote, we learned from her actions that holding down the button that controls the upper or lower light will, after a pause, either brighten or dim that light. Our fan is older than yours, but perhaps yours works the same way?
