Having problems with your Hoover U6437-900 / U6439-900 Windtunnel Bagged 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.


Answers :

My bissell 6590 works fine with hose attachment. Motor shaft turns when belt and roller are off. When belt and roller are on it's noisy and smelly. Now one end of the roller actually melted in the holding slot. Do these rollers wear out like this or should I be looking for another problem.

Belts Burning On our Ultimate G, belts are lasting about 2 uses and they smell and burn off. I am looking at the roller and I can see a slight grove where the belt rides. Is it time for a new roller. I am sick and tired of replacing belts and smelling up the house. Thanks Dusty


Yes, replace the brush roll, the ends or end is probably bad and causing the belt to slip and burn up. ... Kirby Ultimate G Bagged Upright Vacuum

My Dirt Devil Vibe bagless vacuum started giving off a burning smell. The brush roller was jammed with hair. I immediately shut it off and cut the hair out of the rollers with scissors until it turned freely. When I turned it back on, the smell was gone but there's no suction now. Did I ruin the belt or something else?


It's more likely there's a clog in the hose somewhere, possibly where it connects to the power nozzle. Detach hose and check the PN. \015\012If there's no clog in the PN, detach hose completely from machine and try to drop a marble or coin th ... Windsor SR12 Sensor Bagged Upright Vacuum

Motor is sparking and smells like burning rubber. When it first happened I thought the vacuum had something jamming the beater bar. That was the smell it had, like when the belt gets burned. But when we turned it over, it wasn't jamming. Took off the base plate and turned it on. The motor area is sparking and it makes a weird noise (I assume that is because the motor fails and restarts). I looked for loose wires, can't find any. I believe I need some sort of part replaced, maybe even a n

Hoover F6025900 Steam Vac Widepath LS, I own this steam vac and I found bits of rubber under the machine when I turned it on, smelled like burned rubber from a belt? Can you please tell me if there is a belt on this carpet cleaner and if so, how to access the belt? I have taken out some screws and still cant get to the belt? Thanks


Well there is no belt, and not sure what the rubber would be from, everything is plastic or metal. Unless it is really an electrical smell, which means the motor is going bad.\015\012\015\012 ... Hoover Vacuums

I want to brush the pile up on my carpet do I need a special attachment to do this??. I have shampood it and it still seems a bit flat. When I shampood no water/foam filled up in the front tray???I am sure I had attached everything correctly. The only thing I can think of is when I attach the brush and tray to the front of the machine, do I turn the handle back to the right way up, or do I leave it upside down, this is the one that picks up the belt.

Sewing machine Guru needed ;) Elna Grasshopper (new to me) circa 1950 The light works, but there was no hummm when knee pedal engaged. I have the motor out, and it is very stiff to turn. I'm at a total loss when it comes to motors and electricity. It doesn't smell burned, doesn't smell at all beyond normal machine smells.

I have a Eureka 4800 series the Boss upright with a bag and Hepa filter. I love it! I was just vacuuming with the hose part and all was well and then suddenly the lower brush came on and a "burning" smell followed. Thought it was the belt so my husband was going to put on the new belt which I had on hand! When he turned it over, the "bar" that holds the belt looks as though it "shot through" the plastic side of the housing on the vacuum. There is melted plastic on the outside of the vacuum and o

I was just using my Bosch 1450W bagged vacuum and all of a sudden, the motor just shut down. No warning, no problems. The light still turns on, but the motor is unresponsive. There is a clean bag and filter, and nothing caught in the front roller. The motor sounded fine - no shaking, or weird frequency variations. There were no weird smells, just a little bit of heat, but nothing beyond normal. I've had this thing for several years, and never had a bit of trouble with it. Any suggestions

I have owned my kirby sentria for 2.5 years and have had no problems until now. The vacuum still works but I cannot lower it all the way down or the light will turn off and it will start to smell like something is burning inside. I use it on the 2nd or 3rd setting with no problem. I have changed the belt and cleaned all the hair and strings that were on the roller but it still has this problem.

My vacuum makes a really loud noise when I turn it on. It was working and now it smells like something is burning. I check the belt- it looks ok.


The belt may look okay but it still can be stretched or worn and can be slipping on the motor shaft and thats why you have the burning smell. I would try changing the belt.

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

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.
