Check the switch to the brush bar it might not be in the right position it needs to be in to run or not run should be in a little slot that turns it on and off

Are you sure you have the correct belt? The proper belt is # 59156500. It is 5/16" wide and about 2 1/2" in diameter. This is not a common belt.

First be sure the switch/circuit breaker on top of the nozzle is on. The brush also will not turn unless the handle is released and tilted back. This model of Hoover has a gear drive to turn the brushes. This was VERY prone to problems, and Hoover discontinued making replacement parts for it several years ago.

Your belt is loose, you need to buy a new one

check the belt of the brush roller. Or check for a clog

check the belt it may be stretched or broken...also carpet and hair or other debris around the bruches may have it in a bind,,..remove the 2 screws holding the bottom on to check this

Your beater brush could be frozen. Meaning the bearings are shot. You'll need to replace the brush roller

Sounds like you have a bad brush roll(48414115), take it out and see the the ends turn freely or not, if not, then replace it. Also check the the slots that the brush roll sits in to make sure they haven't melted. I am assuming that the motor is running, if not, then it may have froze up.

Either the brush rolls are bad, at the ends, or the gear/motor asm. is bad.
