I have a VAX V12 vacuum cleaner which suddenly stopped. The smell indicated Carbon Brush Problems. I contacted a service agent who told me that it was not possible to change the Carbon Brushes brushes on this model and they would need to change the Motor Unit.. To me this sounds very unlikely. Two questions please. Is it possible to change the Carbon Brushes and how do I get the cabinet apart which looks very difficult. I am well qualified electrically to do this job. Regards James Beech

Hello can you help me please? I have a Kirby G4 vacuum cleaner, It did work ok until it started to give off burning smell and lots of sparks from the brushes. I have changed these brushes, the motor still rotates but it still gives off sparks and burning smell. Do i have to change the motor as well? Can you help please? Thankyou Martin


Some debris, even sand or dirt, probably got into the motor, causing damage to the armature. If this is the case, you will need to replace the motor. The burning smell from the motor is generally a sure sign of a bad motor. ... Kirby G4 Bagged Upright Vacuum

Burning smell There is a burning smell when I run my Kirby Ultimate G.  The smell seems to be coming from the belt.  I looked at the brushes and they are spinning so the belt is working.  the Post on the vacuum is getting very hot not sure if that is normal.  What is causing this?


Unlock the sweeper brushes and take them out. on each end is a cup bearing and should be free of debris.then check around and under the belt and likely there is debris wrapped around it.the post is getting hot as your pulling too much of ... Kirby Ultimate G Bagged Upright Vacuum

Burning smell how do I get the bottom section apart to clean it out- burning smell when i have the spin brushes turned on. Any help would be appreciated cause I love this machine and hubby told me it couldn't be taken apart to be fixed. Thank you.


The bottom doesn't come apart. you have to remove the top cover to get to any components. But if you have a burning smell, then it is probably ther motor and would have to be replaced. Motors cost anywhere from $70 to $90. ... Hoover SteamVac F5914-900 SpinScrub Upright Vacuum

The brush roller stops turning and I can smell the belt burning, then it will catch and start working normal. I looked under the plate to check the belts and they looked okay and no hang ups of string or anything. The only thing that seemed weird was that the smaller belt that actually attaches and turns the roller is a bit loose. The larger belt is tight but looks like its the one that is burning and causing the smell.


Better to replace both belts the smaller one is stretched out thats whyits slipping ,be sure to clean the old rubber off the motor shaft before replacing the belts.it will cause the new belts to run unevevly and go bad before their time ...

The brushes spin very, very slowly and stop altogether sometimes - like they just don't have any power behind them.I've cleaned the brushes and also turned it on without the brushes inside to see if the female plug that the brushes go into turns - it does, but not very fast. My husband said he thought he smelled something - like burning. Is there a way to take the underside cover off and clean something?

Bissell 6595 problems with roller brush. I've had this happen with two of the same model. Each one didn't last more than seven months! First, it became loud when vacuuming, then there was a burning smell. When you try to replace the belt, you see that won't do any good because the fitted end of the brush is melted. The housing part the roller brush fits into is melted too. There's no place for the roller brush to fit into. I tried to upload pics, because I don't see how replacing the roller brus

My Bissell Model 3760-4 is not working properly. The belt has been replaced (and checked 3 times), but the brush bar does not move when the brush motor button is on. The little metal turning piece that turns the belt is turnable with one's finger when the belt is off, but when we put it all back together and turn on the vacuum, the brush bar does not go around and the burning belt smell returns. The portable part of the machine works properly. It's the brush bar. It has been cleared of hair, etc

How to disassemble the brush to empty anything that might be stuck inside of the brush? The motor seems to be overheating, all belts have been checked, all airways are clear and the filter is clean. The vacuum is vibrating and releasing a burning smell, but still sucking up dirt. There is nothing stuck on the outside of the brush, but is there a way to check inside of it to see if that is where a clog is occuring?


If there's a burning smell and the belts are fine, the problem is going to be hot wires causing the insulation to melt, or the motor going bad. Discontinue use and have it checked at a repair shop. ... Bissell 6594 PowerForce Bagless Upright Vacuum

Hoover windtunnel U6425-900 the brush roll is not turning. Both belts are in good shape, I cleaned the brush roll and it is free of debris, the setting is on carpet and the brush roll still will not turn.

OK - so your brush roller is jammed. And yes, the belt is melting! Unplug the machine, remove the belt (you will need another new one anyway) then see if you can turn the roller by hand. If it turns freely without you doing anything else, then you ma ... Bissell 6595 Lift Off Bagless Upright Vacuum

Roller Brush How do I install the roller brush. I didn't pay attention when I removed it and now when I attempt to vacuum my low carpet it doesn't seem to be working. The green light on the head of the vacuum goes out when I click it down to the floor. It didn't used to do that. Plus I think I smell something burning. Could the belt be broken?


Try a new belt. The ends of the brushroller are different sizes, so you can't put it in backwards. There are numbers and notches on the ends of the brushroll. These notches/numbers need to match on both sides when installing it. (probably need b ... Kirby Ultimate G Bagged Upright Vacuum

I have an Oreck XL Platnium. It smells like burning rubber and the brush roller binds and stops as you pull it back and forth, even on a hard floor. I have changed the belt 2 times. I have taken the brush roller out and checked it. It seems to be spinning freely. What could be wrong??

The belt burnt out and it seems as though the red arrown does not release the belt. Like it is backwards from the green arrow. It had a burning smell and the belt broke. Then the second belt started to burn out when the brush roller wasn't spinning. Not sure what might be wrong. Green light will not come on either.


It sounds as if there may be a piece of the broken belt in there. Look carefully with a flash light and remove any remnants you find, using a pair of pliers if you have to.\015\012\015\012Also, remove the entire brush roller assembly and ... Kirby Ultimate G Bagged Upright Vacuum

I have a Bissell pet hair eraser model #3920. It's been working great until last night. I went to use it and the brush won't spin. It also smells like it's burning. I checked the belt and it looks fine, and the brush spins by hand easily. It's not clogged anywhere that I can see. Anyone have any other ideas? This vacuum is only 8 months old.


- Remove the access panel, which is on the bottom of the machine. There are 4 tabs to lift on the access panel to remove. Start with tab 1 then 2-4 tabs.- Check the brush, and belt for any damage. Clean off any debris on the brush. ... Bissell 3920 Bagless Upright Vacuum

My Kirby Heritage II vacuum is not picking up dirt up out of the carpet like usual, and I have to keep setting it lower to pick anything up. I finally get it to such a low setting that it starts sucking the carpet up and makes a whirring noise, and starts smelling. Every time this happens, we find the belt has been burned. We are wondering if the brush roll inside with the brushes that pick up dirt are worn out and too short?
