Having problems with your Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum ?
Belt is hot to touch
\015 Keep smelling the belt burning. flat belt is hot to touch but doesn't seem to be worn out. not clogged and the roller seems to be turning fine. should i still replace the belt?\015
If the belt is hot or you smell it burning then chances are it has stretched a little and is slipping on either the motor shaft or beater bar shaft. If you are sure the beater bar is not restricted from turning then I would just replace it. Try this.. With the power cord disconnected, open the vac head to gain access to the beater brush and belt.. then remove the belt.. place the beater bar back into its holder and see if it easily turns by hand.. if it is free to turn..then plug the vac in and turn it on for a few seconds.. you will see and hear the motor come on but you should NOT smell anything burning at that time. If you do.. you may have another issue with the motor or power cord or both.. if you don't smell anything burning, then disconnect the power and just replace the belt.... Good luck.

HI, my motorized brush barely turns.It makes a hot rubber smell. I took apart and noticed the spindle the belt turns on discolored from heat. Cleaned it, but still no turning of the brush.The vac is a hoover wind tunnel. As it moved accidentally touched the belt/ spindle and burned my hand a little. Very hot in area. Bright spark from motor noted. Was careful not to touch that part!

The original belt on my upright Kenmore Progressive broke and I replaced it with the spare that was in the vacuum. The vacuum and spare belt are about 10 years old. Then the spare broke after one vacuuming session and there was a burning smell coming from the vacuum. I ordered new belts and replaced it with the new belt. It seems to be working fine with no smell. I checked the belt after I vacuumed the family room and although it was in tact, the belt was very hot. Is that normal? Should t

On our Hoover U6445-900 (Mach 6.9) we replaced the small belt that goes to beater brushes in front of unit. Upon starting, the Hoover quickly got hot and smoky. We shut it off and looked things over carefully, but the second try also resulted in friction heat on the belt. Now it appears the belt may have stretched due to heat and the brushes won't spin. Any ideas?

I have an old Progressive vacuum cleaner that says "Hepa Filter" and "Whisper Belt". Not sure what the model # is. The problem is that the vacuum part itself (the part that touches the floor and rolls over) has ejected its filter that we can see through the little window- it just came out under the rollers under the device... we cannot see how to re-insert this piece of filter which looks like a kind of round, flat grey foam/fabric and clearly goes inside- (top of the part that touches the flo

I've got a Kenmore canister vacuum, Progressive 236123, and there's a burning smell from the belt side of the head--smells a lot like hot rubber. I've cleaned the agitator and changed the belt, but I still get the smell. It's stronger when I'm using "carpet" mode than when I'm using "bare floor" mode. Any ideas what the problem is?

I have a dirt devil featherlite plus and all of the sudden it started pushing hard and smells hot. I cleaned the roller, changed the bag, checked the belt. The belt is a little wore, but not bad.

I live in a very tiny 2 room apartment and do not vacuum lots of dirt. I noticed this new vac getting very hot to the touch where the motor is located with only a few minutes of use. Today it just STOPPED. When I felt the canister, it was HOT. It obviously has burned out. Upon closer inspect

Hoover Windtunnel U5750-900 Agitator brush is weak. It turns fine if I tilt the vacuum back, but it slows to almost 1/4 speed when it touches carpet, even on the highest carpet setting. I've replaced the agitator belt twice. The brush used to turn powerfully even on the lowest (Hard Floor) setting. Ideas? I should probably lube the agitator brush ball bearings, and re-check the belt, but, other than that, I'm stumped.
