Every once in a while a squealing noise occurs - it stops tho'. Is this a bearing? Can the motor be oiled? If so, how? Does the motor require replacement? And if so how? Michael J

    this is in regard to a Vornado VAQS 35 AIR PURIFIER!!!! THERE IS NO BELT - IT IS NOT A VACUUM CLEANER. Again, after it runs for a while - a sudden squeal comes from it -- it stops, it keeps running. I have turned it off for now -- does the motor need oil? If so where and what type? If the motor requires replacement can it be done?

Usually, if a bearing is going bad it is pretty consistent in the noise, smoke, burning smell it may make. This sounds more like a problem with the motor to brush belt and tangled up hair, etc. Take apart the brush and clear out any tangled hair, dust, etc. and check and replace the belt.

I believe the bearings in most Vacuum cleaners are Sealed bearings, and are generally maintenance free. Like I said before, usually, if a bearing is going bad it is pretty consistent in the noise, smoke, burning smell it may make.

The squealing you hear is more than likely the belt squealing, if the rotating brush gets hung on something. Or the belt is simply getting old and needs to be replaced. Unfortunately, they don't last forever.

    Try lubricating the fans shaft where it enters the motor with a drop or tow of 3 in 1 oil.

How can I stop the squealing noise in the motor on my Sanitaire wide track commercial vacuum? It's making a squealing the minute I turn it on


Is it the motor or the brush roll? Remove the brush roll and belt and see if it still squeals. If not clean or replace the brush roll and get a new belt. Inspect the fan to insure there is not something stuck in it. If it's the motor you can try to clean it, make sure there is not something stuck in the motor causing the noise.

Brush makes noise when engaged, I put a new belt


You don't say what kind of noise, but if it is a bumping noise or squealing noise, make sure both ends of the brush roller are clean. It may be binding.

HIGH PITCHED SOUNDS WHEN VACCUUM IS ON


Remove all filters and turn on the vacuum cleaner and check the hose for suction.If it has good suction turn it off and remove the belt.Turn it back on and if the noise is still there you have a motor bearing squealing.It's probably time to replace the vacuum cleaner if you have a motor problem.www.sewvac.com .Most of these box store models are designed for replacement if a major component fails.

I need a manual for my kirby vaccum , its making a high pitch noise


A manual won't help you on this one. You have a bad bearing behind the impeller. Ther squeal at first and scream as they get worse. DO NOT OIL IT. That will only attract more grit into it.

My Kirby 2HD has started making an odd roaring noise but still works fine. I have taken the front assembly off and cleaned and adjusted the roller and checked the belt. The noise seems to come from the...


It is quite possible, it just needs lubed. The motor comes in direct contact with dirt so, you have to make sure the front bearing has a drop of oil on it from time to time. If it starts to scream at you within one month, after oiling, the bearing needs to be replaced.

Kenmore upright vac model 33922 - good suction but developed loud whining noise after accidentally vacuuming room without bag. Added bag and changed both filters. Still makes noise. How can I stop noise?


The bag is the first stage in your filtration. Most times what you did will draw fine dust right through the filters and into the motor itself, affecting the bearings and clogging the motor fans, throwing them off balance.
The fact that there is a new noise would seem to indicate bearing problems which will only worsen unless the vac motor is dismantled, fans cleaned and bearings either replaced or cleaned and repacked.

Rainbow SE makes Squealing Noise when switching it...
Posted by ray_s51 on Apr 20, 2008
My Rainbow SE works and runs strong but when I switch it on and off for approx. 20 to 30 seconds the motor makes a loud squealing noise. Do I need to oil something or what? Nothing smells, it does not make the noise all the time, but it does more often than not. Thanks

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Rainbow E Series Canister Wet/Dry Vacuum.

The Rainbow has 3 fans in the bottom of the motor and if they are weak they will make noise from the motor unit. Watch out… the repair of the Rainbow may exceed the cost of a new motor of which will solve your problem of noise and separator --- compare the cost and the labor and make a decision. The separator is part of the armature, the separator should be able to be removed and that might be one of the things making noise. As normal maintenance the separator should be removed and cleaned after every use and re-installed, then place a newspaper or towel under the motor unit and turn on the Rainbow and spin the moisture out of the motor unit. This should be done every time you use it. If you have further questions please feel free to contact your local vacuum cleaner dealer. . So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.

Weird noise


Check to make sure that the hose and the inlet down by the brush roll are open and not clogged. It could be a bad bearing in the motor, if so, you are looking at replacing the motor.
