Re: need replacement motor
Before trying top replace anything, make sure you have power at the motor from the cord. If you have no way to check for power, unplug and change the cord to any other you have around. That will assure that the cord is good or bad.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Sadly Hunter doesn't want people dismantling their stuff and replacing broken or burnt out pieces. They'd rather you buy a new one. If the motor has burned out which is possible a solution depending on how handy you are is simply hunt down a similar replacement and reconnect it.
Make sure the new motor has the exact same leads and connectors as the old one had as some Hunter fans have more than two leads. The model I have has four leads: a black, a white, a green and a red as my model has integrated lighting controls by passed by the motor.
I bought a simple blower motor with the same rating only two wires and with a bit of solder and wire I hooked up the motor and lights separately. The new motor is much faster than the older one so I had to add a tiny 1-way 500 watt dimmer switch to manually turn down the speed.
This one the best brands on the market that I have ever owned.
If the fan motor will not turn on or hums and/or turns slowly more than likely its a lubrication problem.
1. Unplug the fan from the wall remove the 516 screws to the cage
2. Try turning the fan blade by hand if it is tough to turn more than likely it's a lubrication problem
3. You will have two oil holes one in the front one in the back spray WD-40 into these holes, turn the fan blade if it starts to free it up apply more WD-40 and keep turning the blade add more WD-40 until the blade turns freely. Especially in the rear oil hole because this is an oiled bushing that you are adding oil to. Once the fan is turning freely replace the front cage with all the screws plug the fan and I hope this solves your problem. You may add 3 in 1 oil or some other very light lubricating oil periodically.
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.
Isolate power from the fan and see if you can spin the fan blade by hand. It should move easily. If it does not then it is recomended that you replace the fan. The time it would take to replace the bearings in the motor would not be worth your efforts.
Most fans do not have a start capacitor for the reason being they are not under severe load.
Wd-40 is not a very good lubricant. It only lasts fror a few days and then dries up again. In order to get your fan working again, take some 3-in one oil and put a drop at the bearing side of each bearing top and bottom with the shaft upright. Spuin and tap the motor briskly with a small tack hammer or screw driver handle. This will impact and allow the oil to get into the bearings Keep tapping and turning until you feel it lighten up a spin freely. Turn it over and do the same thing again. I garuntee that all will be fine after this.
If the fan does not spin and the motor hums, you have a stuck rotor. It may be due to bushing/bearing alignment problem or a lubrication problem. Try to spin the fan blade manually. It should turn freely, otherwise the rotor is stuck. Remove fan blade and put few drops of lubricating oil on the bushings/bearings and manually turn the shaft to free it up. Alignment of shaft and bushings/bearings must be after lubrication is done and the rotor is still stuck. Move the shaft up and down and side to side until it smoothly spin when manually turned.
There's a rubber circle that is the damper between the blades and the motor shaft that rotates. The circle has spokes connecting the outer ring, which the blades screw into, to the inner ring which attaches to the shaft and holds it. If the spokes break you get the symptoms you describe, motor hums but no rotation, but blades can turn manually if you hand turn them them. If this is the case you need to remove and replace the blade mounting ring/damper. (About 25 bucks online)
