Brush roller won't turn

If you pull it apart make sure the roller and the belt is free of debris. And I would check the belt to see if it broken or real loose. If so contact Shark and see if they will send a replacement . (It may cost a few bucks) At least this is a first start hopefully it helps?

you need to change belt on brush and also check for locked up bearings on brush roller and or debris lodged between brush and guard dislodge if need be or replace bearings on brush roller if they are bad

1) you need a little tight the belt, with the bolts of motor.
2) you must shure if the belt if NOT large or short( in both cases the rollers will NOT run. can be slip. or too TIGHT. and BRAKE the motor.
3) the motor you must test for brush, switch, or open winding.
4) put a little lube in the extreme of shaft rollers,see by turning at hand if they run of course unplugged the power cord.
God bless you

Hello, this is Ava with Think Crucial.

There are a number of reasons why your brush roller has stopped moving. General maintenance to your vacuum is crucial and will help it work at peak performance.

First things first lets focus on the brush roller. Unplug the vacuum and turn it on its side. Look for any noticeable clumps of debris or hair strands that may be caught in the brush roller. Remove these obstructions, probably best to do so with a scissor if it's hair or long pieces of carpet fibers. After removing the debris try manually rotating the brush roller to uncover other hidden clogs. Another thing to take note of is the condition of the bristles on the roll itself. Are they loose or worn down? These are signs that your brush roller is in need of replacing.

While checking out your brush roll you might as well take a look at your vacuums belt. Your belt should be replaced about every three months. After regular usage, the belt will stretch out, lessening the tension on the brush roller. Lesser tension diminishes the brush roller's turn rate and speed. If the belt feels loose then it certainly is affecting your vacuums suction as well as your brush roll not moving at all.

try turning the roller by hand UNPLUG VACUUM FIRST
it should turn very easy, otherwise it is binding
all uprights have this problem eventually
hair and fibers get in roller bushing and seize
luckily disassembling is relatively easy, same procedure as replacing the small belt that drives the roller. Take the extra step and take out the roller slip off bushings and clean everything
have fun

Easy to fix. The burning rubber smell is hair in the roller against the belt! Congrats, you have a healthy vacuum, you are lucky! Unplug the vacuum, remove the screws that cover the belt and roller brush. If you are nervous, take pictures with a cell phone or digital camera as you go for re-assembly. ok, pull the long roller out of it's slot and out of the vacuum. cut all hair off the roller and carefully move the belt from side to side to do the same. If the belt slips off, it slips back on easily. If the area is too tight for fingers guide it back on with any long thin wooden object. You can squeeze the belt to narrow it and slide it back over the thin metal rod that spins it from the motor. Slide the roller through the belt and back into it's slots. If it won't slide back on, turn it a quarter turn. Repeat till it does slide back into place. Put the face plate back on-tighten screws, flip it over, plug itr in and it should work!

You need a new belt. In order to change it, turn the machine compleatly upside down and place the head on a counter, handle on the floor.
There is a L shaped base plate to remove that has 5 screws in. Once the base plate is off, you see the brush roller and a silver shaft directly back from where the belt would ride. Remove the brush roller, place the new belt, Dirt Devil Style 5 ( see link below ) on to the shaft. Then insert the brush roller, so the belt is on the raised carved out section of the brush roller. Grab the brush roller at each end and stretch it till you are able to put the brush roller back into the base. Turn the brush roller backwards 3 compleat turns and the same forward to seat the belt.
Replace the base plate and you're done.

I have had problems with the belts on my Mach 5 overheating (smell of burning rubber) and also with the motor overheating and shutting down.
I learned the hard way that one of the issues might be that the roller/brush on the bottom of the unit has a metal bearing inside the roller/brush that can become clogged with hair (both human and pet hair) which effects performance of the unit.
It’s fairly easy to fix.
Lay the vacuum on the floor so that you can see the roller/brush. Then remove the phillip head screws that hold the protective plastic plate over the roller/brush. (There are about 6 screws that hold this plastic protective plate in place) Also, you will be removing the (1) screw that also holds the plastic plate over the belts. There are (2) belts that you can remove and when in doubt replace these (2) belts for around $9.00.
Once you have the protective plastic plate off that covers the roller/brush disconnect the belt is around the roller. Take the roller and cut off any hair that is wrapped around the roller. Next, grab the roller by each end and twist the ends caps and (1) of the ends will unscrew. Once you have unscrewed one of the ends remove any hair or dust that is trapped under this cap. (Be careful not to lose the small metal washer that sit on top of the bearing)You will notice under this cap is a metal bearing that can become clogged and jammed with hair. The hair should come out fairly easy and allow the brush to spin fairly easy once you have screwed the end caps back in place test that it spins freely. If it doesn’t spin freely replace the roller/brush with a new one for about $23.00.
When you put the belts back on the thick rubber one (Belt # 40201-271) has probably become stretched and should be replaced for about $3.00. The small diameter belt that goes over the roller/brush probably does not usually need to be replaced and does not usually fit very tight. I have heard that people will take the small roller/brush belt and turn it upside down to get a better fit.
I just did this on my Mach 5 and it runs like a new machine. I did end up replacing the roller/brush head.
Hopefully you will find this useful.

no not really if something is keeping the brush rolle from turning then the motor guard will keep it fron running .check if the brush roller can be turned by hand and freely if its real hard to turn then the roller bearings are bad or there are carpet strands tide up around the ends of the roller keeping it from turning correctly.feel free to call me if you need help.i don't charge i just like helping people and saving them money in these rough times.314-628-9153
