Question and Answers


What would cause the brush to stop turning on the powerbrush attachment of my kenmore cannister vaccuum?


It sounds like you are familiar with the inner workings of your vacuum and have checked most options. I found one previous post for a 721 vacuum and attached below if you want to check while you wait for the expert review here. I also added the link to the Sears Store finder link if you need to find a drop off location for repairs. Hope this is of help.

Thank you for your question.

I can understand you wondering why the overload for the roller brush motor keeps tripping.

Either the roller brush motor is seized or the roller bearings on the roller brush are seized and won�t let the motor turn.

  • You will need to open up the cover and examine what is causing the problem.

  • The overload is the fuse and it trips on high amperage from the motor draw.

  • Flip the roller brush assembly over and remove the 8 screws from the base and then flip over the roller brush assembly and remove the top cover.

  • You can then check the roller brush and make sure it is turning freely.

If it is not you may have to clean the bearings on the ends of the roller brush and reinstall.

  • If it is turning freely, remove the roller brush and check the motor by removing the motor cover screws.

  • Once you have the motor cover off you can try to turn the motor shaft over by hand.

  • Return the motor cover and plug the roller brush into the vacuum hose and try to turn on.

  • If it pops the breaker again it is a bad or shorted motor. There are also some electronic control boards that could be shorted but you will need a technician to check these.

  • If the motor comes on and runs ok then you will have to check for any other obstruction.

  • If you can not find the problem I would suggest that you take it in for service.

I hope this will help.

Thank you for using Manage My Life.

A big thankyou to Sam A-- the EXPERT. Your advice about my vaccuum brush attachment did the trick. One side of the brush was turning freely and the other was not. I didn't realize that the rubber end of the brush came off. When I took it off it it was completely encircled with tightly wound hair. When I got all of it off and everything put back together, it worked! Sometimes these things are easy fixes if you just know what to do. That's where you came in. Thank you for saving me a repair bill for something I could fix myself. I really appreciate it.
