Open up the area where the beater is with the belt off. Turn the beater by hand...if it turns hard, the bearings are jammed up with old grease or debris. You'll have to deal with that.

That means you had too much hair in your beaterbar or that you had the vacuum set too low to the floor. The beaterbar stopped turning and the rubber belt was slipping creating friction and heating to the point of melting. When you vacuum check often that the powerhead (beaterbar) is moving. If the belt ever slips it stretches or melts in half and must be replaced.
If you were referring to the motor then there isn't much you can do but replace the motor.

Bissell bagless motor shaft is too hot and melting belts

My guess is that the roller binds on the carpet (high pile?) and the motor shaft, glazed from use, spins without moving the belt and quickly burns a hote through it. I've had that experience!

Hi There,
Ok so I have made a few videos about what to check when you have issues like this.
THere are 3 possible causes.
1. THe bearings in the brush roller are worn so even though you can turn it by hand the belt cannot.
2. The clutch belts are too stretched and are slipping causing them to heat up and start to melt.
3. The roller on the clutch has melted as a result of the heat from teh belt.
From experience the most likely cause is that the bearings are worn and likely the belts are stretched. I will link a video from our youtube channel watch the one I link and then do a search within the channel for DC07 and you will see the other videos.
You should be able to get away with just replacing the bearings or the belts. I will say that if you have got to the point where you are having issues with the front end I would encourage you to replace the DC07 filters too normally they have a similar lifespan.

I have a Eureka Power Plus vacuum, model 4702, type A. To start off, it never really had great suction. Marginal at best. Then today I was vacuuming and smelled something burning and turned off the...

If it is the motor it may smell electrical and the motor is likely shot. It's very possible it needs a new belt. Your model has a stretch belt and they should be replaced at least every six months (even if it's never been used) because belts need to be stretched so far to be installed they will lose elasticity and slip on the shaft which can cause the belt to melt.

I have a Kenmore Whisper Belt 116-50612007. Up until now it has worked tremendously well. Suddenly, it is smoking from the power nozzle when I vacuum. I checked to see that it wasn't clogged up and that...

It's most likely the belt. A loose or worn belt will slip on the motor shaft and cause the burning odor. Take a look at it first, check for obvious wear and/or melting.
However, if the brush is spinning properly, it could be the motor on it's last legs.

The brush bar will not spin. The belts melt when I turn it on and the belt drive is hot to touch with smoke coming out.

The belt is rubbing the foot plate.Check to see if the foot plate is damaged.Allso check the bearings in the brush bar are free and spin without the belt on.If you cant spin the brush bar by hand with the belt not attached then your bearings are seized.Get a new brush bar

The little belt inside the head of the vaccum with the beater bar is not always spinning therefor is melting. Is it normal for the metal pin that it is going around on to get really hot?

The Belt should be changed at this point. This will allow for the proper tension to be on the brush between the motor assembly (metal pin) and the brush so that it spins at the proper speed.

Is it "normal" for the metal pin (motor shaft) to get hot.... not normal, however in the problem you have described, yes it is normal for this situation.

Change the belt and your problem should go away.

Vacuum Belt keep breaking

When your first belt burnt, the burnt plastics goes into the roller ends and then it dries off causing your roller to not turn or put more pressure on your belt. Until you clean that you will continue burning your belts soon after you put them in. You need to add a little bit of WD40 or any other type of lubricant after you remove the tar from the roller.
