If you checked your brush roll, floor setting, and belt but your brush roll is still not spinning, that means you probably need a Shark micro switch replacement. This small switch tells the vacuums brush when to start spinning.
`Tripped` reset systems are the most common reasons for a brushbar not turning, but there are some other less common reasons too. These include: If the bearings on the end of the brushbar have seized, you won`t be able to turn it at all. This will often result in a broken belt as well, so be aware of this.
Should the brush not rotate freely there may be debris tangled around the ends of the brush, carefully remove any obstructions or replace the brush with a new one. We recommend that you fit a new belt and brush once per year to keep your Reactive vacuum working efficiently.
Clear the brush roll of any hair and debris and inspect by placing it on its end and spin. The brush should spin freely. If it doesn`t spin; it may be time to replace.
You may have stalled the brush motor. To reset, turn off and unplug, then plug back in and turn on. The brush roll may have lodged debris or other entanglements keeping the brush from rotating.
There Is Blockage on the Brushroll

There may be debris wrapped around the roller that is preventing it from turning. This is often due to hair, string, or other larger items that may be suck in the roller. Open the brushroll garage by sliding both of the release buttons away from you and then lift off the garage door.

If all you hear from the vacuum unit is a click at the when you try to start the vacuum motor from inside the house, then the motor in the unit is dead and has to be replaced. A strong odor from the shellac, which coats the copper coil windings, is an indicator that the motor is about to or has burnt out.
The roller brush is the combination of a belt, a roller, and sometimes a small vacuum head motor. The roller spins, and the bristles attached to it sweep up debris that then gets sucked into the dirt container of the vacuum. The brush head also helps to pull dirt and debris out of carpets of various pile heights.
Inspect the belt to see if it is broken, stretched out, or out of place. If the drive belt is broken or stretched out, replace it. If the brushroll is sticking, it will cause too much friction and put too much strain on the belt. Remove the brushroll and clean all hair, string, and lint from the brushroll bearings.
On average a brushroll should be replaced every year or two. If you`re not sure if the vacuum is working as good as it could or should be, replacing the brushroll can be an easy fix .
After a year or so, you may need to replace your vacuum`s beater brush. If the bristles seem to be squished, broken or are varying heights, it`s time to replace the brush. These can be found online with the vacuum`s brand and model of your vacuum cleaner.
Unplug your machine to reset the brush. While unplugged, remove the brush window and brush roll from your machine, by pulling the tab. Take out the obstruction that was causing the machine to stop working. Once the obstruction is removed, you may reassemble the brush roll and brush window.
If the indicator light is flashing red, the thermostat is overheating. To reset the thermostat, turn off and unplug the vacuum. Empty the dust cup and filter and assure there are no blockages in the hose. Allow the vacuum to cool for at least 45 minutes before turning it back on.
To clean the soft front roller, simply tap off any loose debris, use a dry towel to wipe the brush-roll clean and remove any debris caught in the teeth behind the brush-roll. Hand wash if needed, using only water, and let it air dry completely for at least 24 hours before reinserting.
Inspecting the Vacuum Commutator for Motor Brush Problems

Test that by turning the motor off and pushing on the center shaft, the armature. If it has any play, besides spinning, then replace the motor. If solid then replace the brushes – motor brush replacement instructions.

Now that I just fixed my Lux Legacy canister vacuum, I need help on my other Electrolux Regency Series upright! The vacuum works fine but the rotating brush does not work and the brush motor does not turn on. Tried cleaning the brush and hitting hte reset button to no avail. This upright has a triple setting switch and I checked the each of the wires seem to be attached. Tried rotating the brush by hand and it would not budge. Was going to “encourage” the brush to turn with a set of articula
ANSWER : There are a couple rectangular holes on the bottom of the power nozzle, beside the wheels. These have tabs in them that need released with a standard screwdriver.
.rogerpotts_10.jpg.Once they release, turn the vacuum over and lift cover of power nozzle at the back. This pulls the front of the cover out of the lip on the “bumper”.
.Once this is done, you’ll need to unscrew the screw at each end of the brush. Lift the brush out and thoroughly clean it, including the ends.

.Check the wiring to make sure they’re connected to the terminals of the motor. Also, check the belt for wear and tear. These belts can last for five years or more, but if it looks bad a good time to replace it is while you have the power head apart.
.When reassembling the vacuum, ensure the belt is fitted properly around the motor shaft and brush.
.Insert the front of the cover first, ensuring the edge fits neatly beneath the lip on the bumper all the way around. It takes a little manipulating to press the back into place. Make sure both tabs click into the locked position. Turn the vacuum over and reinstall screws. Try to rotate brush by hand a few times.
.At this point, plug the vacuum in and turn it on. If the power head doesn’t run, press the reset button. If the power head motor still doesn’t run, it could be due to loose or disconnected wires that lead to the reset switch, a bad reset switch, or even a bad motor. The vacuum needs to be taken to the nearest Aerus Electrolux store for further diagnosis and repair.

Any suggestions as to what could be causing the vacuum to sound as if the rotating brush is being restricted from turning. There was not odor of burning as if the motor was in a bi
ANSWER : Orecks have a plastic fan inside and everything you pick up hits it, sometimes things can get stuck in there or break the fan locking up the motor. With the machine off, poke around where the dirt goes into the motor, behind the roller and see if you can pull anything out.

Infinity Vaccum by Shark, model number NV31COS, will not start. The vacuum was running just fine until it grabbed the edge of a curtain. Turned it off to release the suction. Turned it back on and was working fine. About a minute later the vacuum was making an odd noise. Every 2 seconds or so it would “heave” (lack of a better word) then go away, then come back and so on. Turned the vacuum off and checked for blockage, none that could be seen or felt, and now the vacuum won’t turn. Any suggestio
