Dragging motor and squeak

At the point between the fan motor and the impeller a squeak has developed, and at times the lack of lubrication there has caused the motor to slow way down. Upon sliding the unit out, and manually moving the fan blade, I feel quite a resistance. I have managed to apply some WD-40 to the shaft at that location, but it doesn't last too long, and I have to re-apply the oil again. Is there a better way to apply lubrication to that particular point?

    Thanks for the suggestion. The 3-in-1 helped, and lasts longer than WD-40, but I still need to apply it about once a day. If there were a port on the motor or blower fan shaft point, it would be easier, but it appears that these are sealed. And accessing the points on the motor shaft when only sliding the unit out to service it is a little difficult because of little room.

    I appreciate the time you're giving me. Here is a crude drawing showing the limited lubrication points at which I have applied the 3-in1 oil - hoping that some seeps into the "bearings" by capillary action. I don't want to give up on this unit, and I may eventually tear it down to get to the bearings better.

    I have the exact same air conditioner and it has run fine for 5 years now. However, it recently started making a rattling type noise and at first I thought something inside was rubbing or something. I opened up the unit and everything seems fine - the fan motor spins freely, there is no slop in both bearings. When I run the fan at low speed it doesn't make this noise. When I increase the fan speed to medium the noise comes and goes intermittently. When I increase the speed to high, the noise starts and continues. If I let it keep going making this noise, I noticed the fan slows down a little when its making the noise. Anybody have any ideas what might be causing this?

Never even think WD-40 is a lubricant oil! 3-in-1 in the black/white or red/white can won't work either, it will gum up and turn to varnish very quickly. 3-in-1 electric motor oil in blue/white can might work, but I won't risk it. Use SAE 20 or ISO 68 non-detergent oil ("turbine" oil, machine oil, compressor oil, hydraulic oil, are all OK, but "gear" oils are too sticky). "Zoom Spout" oil is OK, is a lot cheaper, but a little thin (SAE 10, ISO 32); this is not a bad thing, if you can't flush out the old gunk, a little thinner oil may even things out. Don't use engine oils, they are for cars.

    Also, please note that if the bearings are dry, you need to give them a few drops of oil a day, until they are saturated. The bearings are porous, but don't soak up the oil as quickly as a sponge. If overfed, you will make mess. But the next day the bearing surface (in contact with the shaft) could be dry again. A rough estimate would be, if the motor was 5 years old, it could have used 2 drops of oil per bearing per year; but due to deferred maintenance, didn't get any, so it is now begging for 10 drops, etc. So in this case, apply 2 drops a day, 5 days in a row.

Absolutely! WD-40 is NOT a lubricant. I've been using Hoppes gun oil, but 3-in-1 oil will work, and you might find oil labeled for use on electric motors at an appliance parts seller.

    I am having trouble visualizing what is between the motor and the impeller in an air conditioner, but I'm going to talk like it is a bearing.

    I have "saved" many a bearing over the years, and they all go bad again. One lasted most of a year, but all the others failed in less than 3 days. I have used an ice pick to make an oil hole. I have taken motors completely apart to lube them. I have injected several types of grease with a hypodermic needle. It always comes down to replacing the bearing.

    Love your style, but, been there, done that.

I've had my A/C for about 2 years. Last night the blower fan began squeaking badly, stopping when I turn off the fan. How can I lubricate the shaft or seals or whatever for the blower motor?

most blower fans have plastic plugs at each end to remove and lubricate. you have to remove motor from wheel to get to front bushing.

How can I get my Seville desk fan to stop squeaking? When I called their toll-free number, they said their fans don't squeak. Talk about a company being in denial!! Their only suggestion was to take it to...

Remove the guard, remove the fan blade. Lay the fan on its back and drip 4 drops of 3 in 1 Oil down the spindle. Turn the spindle by hand about 6 turns and leave it overnight with the spindle upwards. The next day, run the fan with the blade off and see if the squeaking has stopped. If it has, replace the blade and guard.

If it is still squeaking, it is the bearing at the other end of the motor. That one is not quite so easy to lubricate and usually the motor would need to be fully stripped down, cleaned and lubricated.

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!

Possible lack of lubrication or accumulation of dirt. It is best to remove panel and check for dirt, if so a good wash before lubrication of the FAN and moving parts must solve this issue. Use a degreasing spray like WD40 on the motor shaft and fan.

Seabring frontend squeaksonly when i turn the wheels 04 four door

These problems normally point to component wear, lack of lubrication. or an incorrect adjustment.
You must inspect and test the steering system to locate the source of the trouble. just make sure the parts on front end are lubricated. check the front struts, sometimes if the upper plate goes bad, it will make noises. just check it out. you will find the squeaks !

We have several 11 year old Craftmade ceiling fans that have developed a ticking sound, mostly on the medium speed. Is there a way to lubricate them or is there some other way to stop the ticking?

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.

My Hayward just hums when I turn it on and after a few seconds the breaker pops.

You will need to disassemble the pump and check the impeller. remove any debris and try turning the impeller by hand. If it does not move or is dragging, you will need to overhaul the pump. Possibly a shaft seal leak has damaged the motor bearing(s). Replace the shaft seal and motor bearings. If the motor is badly deteriorated, you might need to replace the motor. Note... the impeller turns counterclockwise to loosen. you may need special tools to grip and hold the motor shaft and the impeller to prevent damage to the impeller. If the impeller is seized on the shaft from rust, you may have to break it to get it off. reassemble with teflon lubricant on the shaft threads when reinstalling the impeller. This will prevent seizure later.

Squeeky humidifier when turn on . Squeaks at random times. Sometimes we have to completely turn it off because it is so bothersome.

Hard water particles will build up in the fan bearings and cause the squeaking. Unplug the thing, and locate the fan motor(s). Place a few drops of 3-in-1 oil on the bearings where end of the shaft is mounted on the motor. This will lubricate motor, making not only run quieter, but faster, cooler, and more efficient.

Hampton bay fan makes squeeking noise

If the fan is fairly new, remove it and return it to Home Depot. It is almost certainly something that has fallen down into the motor and is rubbing loudly enough to make a squeak as the fan runs faster.

The fan itself has sealed lubrication and you don't have to lubricate it.
