Check that there is no build up of fluff or debris in the machine. If the motor is getting hot its cos its not getting enough air ... through obstruction... probably you have something like a screw etc thats touching moving parts and restricting flow. Dont run machine hot... allow to cool right down before switching on again.

After using for a while it gets hot and cuts out. So far it has done this twice and re-started after cooling down.


The cutting out is, in a way, a good thing. Most vaccuum cleaners have a thremal cutout, so if the cleaner overheats it cuts out until a safe temperature is reached to save the motor from damage.

The question here is why is the motor overheating. There are only 2 possibilities:

1: The motor its self is failing and windings in the motor are burning out, causing the overheat. If this is happening, then the overheat will probably be accompanied by much louder noise from the motor that you are used to and possibly the smell of burning emectrical equipment. If this is happening then you should stop using the cleaner right away. Generally the cost of a replacement motor (Unless the appliance is under warranty of course) is more than the residual value of the vaccuum cleaner.

2: The motor is overheating because it is being overstrained. Possible causes for this are:
Dust filters on the machine are clogged (Bagless machines typically have at least 2 filters, one on the exit airflow from the motor and another somewhere around the top of the cylinder. In a Dyson for instance, there is a foam filter in a clip open housing directly above the dust container.

Clean, wash or replace the filters as per the manufacturer's instructions.
If it has a bag, then the pores of the bag may be blocked - swap out the bag.
If it is an upright with a brush, ensure that the brush is turning freely
Ensure that all pipes are free from obstructions, pay particular attention on upright cleaners, to the pipe that leads from the beater brush housing to the waste dust collection

Hoover H3030-006 240 V Motor making a loud sound and burning smell


If you have little to no suction, that sound is happening because you most likely have a clog some were in the vacuum.

smell is probably your motor over working itself do to the clog.

also double check your belts on your brushes that they are moving with the motor. smell and sound could come from the brushes being jammed which would cause the belt to freeze and heat up and could burn the belt and or your motor.

if it is still running though your not in the red yetm so triple check that the machine is cleared off all clogs and jams in the belts and brushes.

Smells like burning


We had this same issue. I noticed it smells like burning plastic. I took it apart and did not find any fundamental problems. Ball bearings on motor are fine, no play. What I did find was that the motor construction contains lots of plastic. It's made in China. Even the brush holder is plastic. Now, this is unusual to me, as brushes get very hot. However, I did not find any issues of melted or softening plastic when running. I used a laser-guided thermometer and measured about 170 degrees F on the metal portion of the brush holder. Nothing unusual. Some parts reached above 200 degrees F. Again, nothing unusual. The only unusual issue is that many of the parts are mated with plastic parts. That's where I believe the problem lies. When the motor is new, the brushes don't make full contact. Therefore, full power draw is not achieve until these brushes wear down a bit. After this point, the brushes reach maximum power delivery and reach maximum temperatures. This is why I believe the vacuum didn't exibit any smell until a few months later, at least, for us. In conclusion, I didn't find anything wrong, except that the motor is cheaply constructed. It isn't going bad and well likely last quite a while, IMHO.

Brush will not turn


Assume that the belt is broken to the power brush /head. Did you happen to smell burning rubber or see small pieces of black rubber? Look in your manual for replacing power head/brushes belt! With the unit off , try turning the brushes by hand and clean them off of debris, etc., as well while there. See if you feel some tension or hear the motor moving inside, indication that the belt is still attrached and if it doesn't seem to have any resistance and you see small pieces of rubber and /or, the band/belt may have just broke from normal usage. WalMart sells most types or your local vacuum repair facility.. check the Yellow pages and let your fingers do the walking.. Good luck

Panasonic MC-CL673 vacuum is not getting up to speed and smells


Even though the brush is spinning, you probably need to replace the belt2_bing.gif because it is stretched. It is probably slipping on the beater bar. This is causing the smell (burning rubber). I don't believe it is your motor. :-)

Wertheim vaccum 3180


most vacuums use a belt that runs from the motor to the front brush. and when the brush gets jammed the motor continues to run and burns the belt (probably what you smelled).
you'll have to turn it over and remove the base plate and replace the belt.
use the old belt to find a match
hope this helps.....jay

Vacuum shuts off and has a burnt smell


Hi,
Try removing the drivebelt, and try running it to test like this. The brush bar will not turn, but it should function normally without smell at this point. If it doesn't, you may need a new motor as I think the brushes may have worn down - producing an electrical type burning smell.

If it runs fine without the belt attatched, then there is probably a build-up of hair or threads at each end of the roller stopping it turning freely. With the hoover off, check it turns freely and easily. A small metal nail file or similar is usually a good tool to clear it.

If the roller is stiff, the belt will not turn easily, and overheat on the motor spindle - causing the burning smell.

Burning smell


Unlock the sweeper brushes and take them out. on each end is a cup bearing and should be free of debris.
then check around and under the belt and likely there is debris wrapped around it.
the post is getting hot as your pulling too much of a load.
though if it continues the motor may have a bad set of motor brushes (inside the motor) or bad wiring (kinda unlikely).

Burning Smell


Check the carbon motor brushes, there might be arcing on the armature. New brushes may help if the armature is ok.
