Heating by rollers not rotating

Pat, if clean and belt OK, motor has burnt out, can be replaced.
Dyson DC24 How To Replace The Brush Bar Motor

The motor rotates the bar. My guess would be that the rubber belt that goes from the motor to the belt has fallen off the bar , broke, or the bar is not seated properly. GOOD LUCK FRIEND.

Use only BISSELL Style 10 Replacement Belts (#32074) in your BISSELL PowerForce Bagless.

1. Unplug cleaner from electrical outlet.
2. With Rotating Floor Brush removed from vacuum cleaner, grasp old Drive Belt and remove from Motor Pulley. Discard old Drive Belt.
3. Place new Drive Belt over Motor Pulley and stretch other end over Rotating Floor Brush in the space between the bristles.
4. Place ends of Rotating Floor Brush down into slots on sides as shown.
5. Turn Rotating Floor Brush by hand several times in the direction of Motor Pulley. If properly installed, Drive Belt will center itself on Rotating Brush.
6. Reposition Brush Cover and snap back into place. Check to be sure all three latches are secured.
7. When you turn on the vacuum, do you see the motor that spins the belt spinning at the bottom? If not, it sounds like you may have a burned out motor.

The number one cause of brushes not rotating is a broken belt. If you remove the four screws holding the bottom plate, you'll see a short, wide rubber belt that goes around the roller.

If this is broken, it's easy to replace. They do break because of age and wear. One of the leading causes of breakage is when the roller gets something - a curtain cord, for example - wrapped around it. If you don't immediately shut off the vacuum & remove the cord, the belt will continue to try to turn the roller (which can't turn), and this generates a lot of heat in just a few seconds.

The number two cause of brushes not rotating is, as suggested above, something jammed & wound around the roller. It's always a good idea to turn the vacuum over periodically and clean the roller... including using scissors or a knife to snip & remove wound hairs & threads. A clean and healthy roller will help to keep your belt happy!

The brushroll might be restricted from turning freely causing the belt to slip on the motor shaft.

replace the drive belt.
turn the vacuum over. take the buttom plate off, you can access the roller (beater). there should be a belt attached to the roller and the motor shaft.

Hi.

If the motor is struggling check to see how easy it is to rotate brush by hand it is stiff to rotate the bearings in the roller may be siezed or the roller could be clogged with hair etc check it & let me know what your findings are.
