    Brush not turning - small belt seems loose.  Any suggestions???

    i have the same problem - thin belt feels loose. I think it might be related to the carpet/floor switch which tensions that belt.

The rollers on each ends get tangled with hair etc...

Hello,

You could have a broken fan in the motor and need to replace the fan. If the noise is coming from the brush area of the vacuum, you probably have a broken bearing in your brush roller and would need to replace the brush itself.

Hope this helps.

Hoover WindTunnel Self-Propelled V Belt


Hi, That is what was happening to my Windtunnel. Until I looked at the little round disk "plastic". there was a crack in it and this puts pressure onto that V belt to make the brush spin. I have a replacement idler arm assy unit which has to be replaced. I hope this helps Cindy G.

Brush won't turn and self propel doesn't work (by 2 users)
Posted by brucelk on May 24, 2008
I have replaced both the v-belt and the larger belt with Hoover brand belts and the brushes still don't turn properly and the self-propel function doesn't work. It seems that when I lower the handle all the way down toward the floor it works fine, but no one can vacuum this way. Is there an adjustment to belts to tighten them up? Otherwise I have to get it in to the only repair shop in town which is an hour's drive.X

1 Other User Has the Same Problem Comment by chartsell, posted on May 29, 2008 I have replaced both the belts as well. I have tightened the screws as someone else as suggested. The brush still will not turn unless you lower the handle almost to the ground. Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Hoover U6437-900 / U6439-900 Windtunnel Vacuum. It is not so much the belts, the 2 belts are only part of the solution. The average belt change is every 4 to 6 months as a rule and to change them @ the same time. The Hoover Self-Propelled works on when the handle is lower to a comfortable position then the self-propelled drive may just need and adjustment. There is a self-propelled rod that controls the self-propelled feature and it either needs adjustment or replacement or the part that hold it may be broken but either one can be fixed. So feel free to contact your local vacuum cleaner dealer with questions. So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions.

BELT TO THE BRUSH SEEMS TOO LOOSE EVEN WHEN REPLACED


Hoover U6437-900 U6439-900 Upright
LOOSE BELT. THE BELT IS STILL LOOSE EVEN AFTER REPLACING

I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
The reason it seems like the belt is too big is probable correct, you may have the wrong size belt for your vacuum, use genuine belts – your particular model is a self propelled model and takes two (2) belts and they should stretch on very tightly and snug and it is smart to use the genuine belt package for the model that you have and we Recommended the belt change for flat belt(s) are 4 to 6 months for better cleaning
They should be tight on the belt pulleys in order to do the best cleaning – use genuine belts
