When the filters are not cleaned enough, or the machine is clogged the motor strains so much that it pulls the motor fan apart and that's probably what your hearing.

My vacuum seems to be overheating rather quickly. How might I fix this issue?


HI, it's Jim from Crucial Vacuum!

Your vacuums motor may be running hot for a number of reasons. Your vacuums filters may be blocked, or your vacuums bag/dust bin may be full. Be sure to empty the bag and clean/replace your filters.

Be sure to check your vacuums belt. On the other side of the belt is usually the drive shaft or motor pulley. If the belt isn't on properly it could be straining and overworking your vacuums motor, which in turn would overheat the motor. For optimal performance, the belt should be changed out every 3 months.

To find the belt part number compatible with your vacuum, please refer to your manufacturer manual.

My vax power 8, 2200 watts 300 air watts 4L capacity upright Hoover is brand new, I emptied out the dust/dirt collecter and cleaned the motor filter yesterday for the first time, i switched it on and all...


I had the same problem. It looks like the seal on the lid on the bottom of the cylinder has fallen out when it was emptied. There is no longer a proper vacuum being created so you don't get the cyclone effect and the dirt doesn't collect where its supposed to. it just clogs up the filter. I put sellotape to seal the lid and it works fine.

This sounds like your motor going. If it winds up then down it could need new motor brushes or a new motor. Also, if the smell is kind of rubbery it could simply be the powere nozzle belt. Hope this helps, Chris

After running for 15 minutes, the windtunnel vacuum cleaner shuts off. It will not restart until it has been off for 30 minutes. Could it be overheating for some reason. All of the filters are clean;...


It's not necessarily overheating, but the thermal-fuse is definitely tripping and it takes 30 minutes to reset. There are several causes of this (in most common order):

1. A blockage in the suction system or a full dust tank
2. Dirty filters (Don't forget to check the air outflow filter at the back)
3. A worn belt
4. A faulty thermal fuse.
5. A faulty motor

As you've stated that the dust tank is empty and the filters are clean (don't forget to check the HEPA / air outflow filter at the rear), let's look at the other options.

Check the suction is good by putting your hand over the end of the hose and seeing if it will stay attached to you hand upside down.

Next, check the belt isn't slipping. Lie the hoover on it's side and check the rollers are turning constantly and at high speed. This isn't foolproof as it doesn't account for the extra friction of the brushes on the carpet, but it's a reasonable test. A worn belt wont necessarily be cracked. It can stretch and slip without cracking. Also, when a belt is slipping, you can usually smell burning rubber.

If the hoover runs ok for 15 minutes and there is no burning smell from the motor, then it's more likely a faulty thermal fuse than the motor itself. They are replaceable but unfortunately, thermal fuses aren't always sold separately and sometimes you have to buy a new motor (!!) to get a new fuse. Hoover are one of the best manufacturers when it comes to buying spares, so you might be in luck.

I've removed faulty thermal fuses from vacuums because a spare wasn't available without buying a motor. However, I have always done this with the owners full consent after explaining to them that a safety feature has been removed and they should avoid using the vacuum for prolonged periods without letting it cool. I also test the rest of the vacuum fully before returning it.

If you want to try removing yours, it will be attached to the motor with simple spade connections, but you do this AT YOUR OWN RISK. The danger in doing this is that the motor will burn out if it gets too hot, rather than being switched off by the fuse.

Beater brush is good, vacuum running no suction


this sounds like your vacs dust passage from the rotary brush to bag is blocked ? you can diy this if you turn vac over to show the brush and covering cover you will see cover is held by some screw/bolts ? remove these and cover then the brush assy is slotted in place either side on bush/bearings and the drive belt is around the brush memorise how it fits! then gently/carefully lift brush out the belt will create spring action once brush removed you will see where the dust travels thro an arpeture on the belt side of vac this usually is where blockage is clear it out and any other within the area of brush then reassemble and check vac

Hi there. In Panasonic vacuums2.gif, there is a thermostat protection on the motor. It will automatically shut off the motor if there is no airflow through the motor. This is typically caused by a clogged hose. Typically, if your dust container is that full, there could be backup in the hose. Or the dust container being too full could also or otherwise be the problem. Check your hose for blockage, let the machine cool off, it should start up again

Eureka Altima Bagless Upright Brush is not spinning


You probably just have a broken belt. The belt needs to be changed about every 6 months regardless. I believe yours takes a style EXT U(Extended life upright), or a regular Eureka "U" belt works fine too.

Burning Smell coming from the moter


This could be a motor problem. There is always a slight blue arcing that occurs when an electrical motor runs and can be visible through the exhaust vent, but any excessive arcing indicates a problem. If the carbon brushes are sticking, this will cause excessive arcing and can be corrected by an experience service person, but if there is any electrical failure, the motor would have to be replaced. There are no parts available for these motors and the expense of replacing an armature (the likely culprit) would be more than the motor. This could also be as simple as a worn belt, but usually, belts will not produce the smell your describing. When a motor is burning out, it will produce an acrid odor that will linger for a long time.

Bad Motor


That dust is from the carbon brushes on the motor. You may need to check them, and also clean out the motor compartment. A slight noise could be a motor bearing starting to go. Does the smell like rubber or electrical. If rubber, then the belt has stretched and needs to replaced. If electrical, then something is causing the motor to run hot, like a clogged filter, or it could be a motor going bad.
