How to Identify and Fix Common Vacuum Problems ?

If you`re smelling rubber, the belt has either burned out and snapped or the belt has become so stretched out that the roller is not moving and the vacuum belt is getting super heated from the motors RPM.
A strong odor from the shellac that coats the copper coil windings is an indicator that the motor is about to or has burnt out. If the motor is still running, even if it turns on and off by itself as it is heating and cooling, you can still run the motor until it gives up for good.
Carpet cleaner smells like burning and may be caused by overheating debris in the machine or a malfunctioning motor. To resolve the issue, unplug the cleaner, inspect for blockages, clean the filters, and check for damaged components. If the problem persists, contact a professional or the manufacturer for assistance.
Vacuum cleaner motors can sometimes start making noises of either a dull or piercing kind. Dull sounds can be caused by hair or pieces of string getting wrapped around the impeller, preventing the motor from turning properly. Piercing noises are normally associated with worn motor bearings.
Burning Plastic: The acrid odor of an electrical fire is often described as that of burning plastic.
When the oil level in your vehicle gets too low or the oil gets old, you might start to smell burnt engine oil in one of its many forms while behind the wheel. These smells indicate that your car needs an oil change and that it`s time to schedule an appointment with your local maintenance center.
Typically, a vacuum leak will cause situations like hard starting, rough idle, excessive fuel consumption, and engine codes. You might even be able to hear a leak – sometimes a whooshing or whistling sound can be heard with the engine running.
How long do vacuum cleaners last? According to Consumer Reports, vacuum cleaners last a median of eight years. But the lifespan varies wildly by not only brand but your own personal use.
A clogged filter in a Dyson vacuum can create a muffled sucking sound or a high-pitched squealing during use. Additionally, as the filter fills with dirt and debris over time, all the built-up debris begins to emit a burnt-smelling odor. You may need to remove and clean out the vacuum`s filter.
Blockage – when a vacuum cleaner becomes unusually loud, it is normally because of a blockage of some sort. This is a problem that is easily solved by turning off the cleaner, check for blockages in the pipes, and remove them. You can also check and empty the canister to remove any possible blockages there as well.
Your Vacuum Pump Is Noisy

Sometimes, extra noise can mean that there are pieces of debris stuck in the system rattling around. It can be an easy fix—just locate and remove the debris. A loud pump could also mean you have worn bearings that need to be replaced or lubricated.

At the point when they hit minimum pressure levels, the pumps may also rattle. In most cases, these pumps are dirty. The space between the pump chamber walls and the vanes is sealed tight so that there is a layer of oil. This oil can transfer from the pump into the sample chamber unless preventative steps are taken.
Bad smells, smoke and frayed wires are the basic signs of a burned out motor. It would be best to bring the plane in quickly and replace the motor. Great advice but watch the esc. If you do blow the engine or esc deadstick and land immediately or as quickly as possible.
The reasons causing a motor to overheat are varied. These include improper wiring, loose connections, or undersized line sizes causing a voltage drop at the motor. In other instances, slippage from loose belts transfers heat to the motor through the shaft.
The oil is probably leaking down onto the hot exhaust system and burning off — leaving an odor but no drops. As long as the oil level doesn`t drop below a safe level, this leak isn`t harmful. But if you`re going to keep the car, I`d recommend having the gasket replaced.
In many cases, the smoke you see is actually mechanical pump oil vapor. Many people tend to think that whenever there is smoke emitting from the pump, it means there is something wrong with the machine. But, oil vapor or oil mist is a natural by-product of creating vacuum in an oil sealed mechanical pump.
Vacuums cleaners can smell from for various reasons; pet dander, moisture was sucked up… The most common cause is old dirt sitting stagnant in the collection chamber, bags, or filters. Vacuum bags should be changed every four to six weeks or once full.
As the cleaner head and filter fills with dirt and debris over time, all the built-up debris begins to emit a burnt-smelling odour. You may need to remove and clean out the vacuum`s filter. We need to advise you to stop using your machine and request that you contact your local customer support team.

Motor is sparking and smells like burning rubber. When it first happened I thought the vacuum had something jamming the beater bar. That was the smell it had, like when the belt gets burned. But when we turned it over, it wasn’t jamming. Took off the base plate and turned it on. The motor area is sparking and it makes a weird noise (I assume that is because the motor fails and restarts). I looked for loose wires, can’t find any. I believe I need some sort of part replaced, maybe even a n
ANSWER : From sound and description most possible is motor is burnt up sparks usually mean metal on metal either bearing or bushings went on motor if u can jiggle the shaft thats bearing if u rotate the shaft by hand and feel and or hear rough grinding the brushes are damaged and the (windings)are also would need to replace motor oreck has a costumer service 800 989 3535 number give them a call not always but some times they will ship a replacement part for free

Bad Motor I have purchased two of the Kenmore direct drive beltless systems with Progressive systems. The first died after a year, the vacuum motor start making a grinding noies. I pulled the side HEPA filter and could see a fine coating of graphite like dust. Took it to a vacuum repair shop. They said the brushes were going and thus the motor was shot. I liked the vacuum and bought a second, 1 year later the motor is making a slight noise that and removing the HEPA filter I find a slight metall
ANSWER : 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.

HI , I REPLACED MOTOR BRUSHES ,BUT MOTOR IS MAKING A FUNNY NOISE ,AS IF MOTOR IS LOOSING CONTACT ,LIKE A BURNING SMELL. CHEERS
ANSWER : Hi there,
.Most likely you have a damaged commutator. I used to change the brushes on the dyson vacuums but what i found is that it is almost never completely successful. THe Dyson motor is not as good quality as say a miele and when the brushes go they normally cause damage to the commutator. THe best bet is to replace the motor. If you were able to swap the brushes a motor change will be easy for you. If you are in Australia you can get the motors from VacuumSpot or Nelson Vacuums.

Makes a loud noise like a grinding noise then smokes comes out and it smells like burning rubber? When I take the (rod) brush off with the belt then run the vacuum there is no more noise? Please help me thank you
ANSWER : Your belt is worn and stretched and so it is slipping on the motor drive shaft. That is why it is noisy and smells like burning rubber. You simply need to replace the belt. You can get replacement belts here:
