Fan sweaks, is it a bearing?

Vornado makes several fan models. Whether yours has ball bearings, sleeve bearings or another type is unknown. Most manufacturers of consumer grade fans use "permanently lubricated bearings" and require no additional lubrication by the owner "for the life of the fan".

If yours does accept lubrication, you should find a "filler neck" at the front and rear of the motor housing - directly over the motor's shaft (that the fan blade is attached to). A few drops of a light bodied machine oil in each should quiet the squeaking sounds (if coming from the bearing). If there is no such filler neck on the fan, you could unplug the fan and rest it on its back - fan aimed straight up. Squirt a couple drops of oil on the shaft - close to the motor. Because the fan is pointed straight up, gravity will draw the oil down the shaft into the bearing. You may not be able to access the shaft at the rear of the motor without some dis-assembly however. You should not attempt dis-assembly if you're not sure how to go about it. After the oil has run into the bearing, you should spread out newspaper or rags under the fan(or better yet - brought outside - before powering it on, as some oil may be cast off the shaft if it spins fast enough or if there was an excessive amount of oil applied to the shaft.

I hope this helps & good luck!

Noise some times and fans dont work some times

99 out of a hundred times - when the fan motor on a window unit 'makes noise and works intermittedly,' you have a bad fan motor which will require replacing.

Sounds as if the fan motor's bearings are making noise - which - would account for the fan working only part time. The reason being is that the 'bearing noise' you are hearing - is a result of the bearings being wore out - thus it causes the fan motor to heat up and 'go off' - on the internal overload' which is built into the fan motor.

Like I said above - most commonly the 'fix' is to replace the motor.

When turn on blows cold air but makes loud whining noise like rubbing on something. almost a whine sound

sounds like your bearings are out on your fan motor. Some of the older fan motors have places where you can oil the bearings but most newer ones do not. Unless you have a place to oil the bearings and they are not already too far gone you best bet will be to replace the motor. Once the bearings start howling in the way you described it is time to start looking for a replacement. It is also possible (although unlikely) that the noise you hear is (a) the fan blade hitting part of the frame. (b) the bearings in the compressor.

My heater fan is turning on and off, and it sounds horrible when it does work. Is it the resistor pack? I only ask because of the noises.

It is not probably the resistor pack, because that only is in circuit at lower speeds, and would not cause noise.
If there is not something in the fan, like leaves, then it is probably the fan motor bearing.
If you can get at it, you could try lubricating it. Thin sprays get in better, but don't last as long.
Heavy grease is best.

Power light is on, water is up to fill line, dials are set to max humidity and fan speed, but fans do not spin. Tried to spin fans manually but they will not spin on their own. Left fan stopped spinning...

Do the motors feel warm-- maybe even HOT?-- Like they have electric current, but the bearings might be seizing up?
You mentioned one stopped spinning awhile ago--- and the other one was OK-

It sounds like the bearings are dry and worn on the fans-- (How old is the humidifier?)

The bearings CAN be cleaned up and lubricated, if you are into tearing a motor apart, and servicing the bearings-- Are you ready for that? You will have to remove the motors from their mounting, remove the fans, split the end bells, and clean and lubricate the bearings deep inside.

Let us know how much further you want to go-

My 1992 cadillac deville radiator fan comes on and blows the fuse, causing overheating

It is possible that the radiator fan bearings are dry and causing extra drag on the motor and blowing the fuse. Without the fan operating you will experience overheating. The bearings are usually a plain bronze bush type and the lubrication dries out eventually. You could try removing the fan assembly and carefully dismantling the motor. Once apart check for worn out brushes and if they are OK, then soak the bearings in engine oil and reassemble. The bearings are self aligning but once it is running after the motor has been put back together, give the motor body a light tap on the sides near the bearings to make sure the rotor is running free. If this all sounds too difficult, you may be able to get a replacement fan assembly from a salvage yard.

Dehumidifier makes a lould clanking sound when the fan spins. I took of the back cover, the fan is not hitting anything, sounds like it is coming from inside the motor.

Sounds like a bearing went bad. Unplug the unit and grab the fan blades and move them. If they slop around inside the motor, you have bad bearings.

Noise in freezer..sounds like the blower fan .Still blowing air in but makes noise

Good day,
A fan motor with bad bearings is not unusual, Remove the panels, and inspect the fan motor. On occasion a piece of ice could be hitting the blade.
If not you'll need to replace the motor. If you try to oil the bearings, it may help for a while, but the bearings are usually scored.
Most appliance parts houses will carry the motor. If you don't take the motor with you, make sure you have the complete model number with you.
On GE machines, it's recommended you change the blade as well.

Thank you for using FixYa

Carrier Air V unit with loud noise

If it sounds like a scraping noise it could be the motor bracket ah broken and the squirrel cage (fan assembly) is hitting the fan housing, if it is more of a squeal than it very well could be a bearing. Very hard to guess without seeing or hearing it.
