How to Identify and Fix Common Vacuum Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :

Some vacuums have an in-line thermal fuse (often located between the switch lead and the motor coil). If the fuse is blown it will need to be replaced. – Check your home circuit breaker – it may have tripped.
A standard 13 amp domestic cartridge fuse would be fine.
Check that the vacuum cleaner is plugged into a working power outlet and that fuses and breakers don`t need resetting. An activated thermal cut-out due to a blockage is the next most likely cause of the problem. Check for blockages in the hose and filters, and remove any obstructions that you find.
VOLTAGE TYPES (VAC / VDC)

This means the fuse can be used in a circuit he voltage maximum operating at this voltage . For example; if your fuse was rated at 250VAC, it could be used in a 250VAC circuit or in a or less lower voltage circuit such as 12VAC, but it must not be used in a circuit operating above 250VAC ie.

If you have ruled out an electrical problem in your house then firstly check your Dyson`s fuse, only replace it with a 13A fuse which is usually brown in colour. If you replace it with a smaller fuse it will blow that fuse immediately and lead you down the garden path to a problem that may not exist.
Micro 2 & Micro 3 Blade Fuses

The smallest blade fuse currently available is the Micro Blade Fuse. They are available with either 2 or 3 metal terminals (prongs). The two-prong Micro Blade Fuse is known as a Micro 2 fuse has a current rating range of 5 to 30 Amperes and is 9.1mm wide, 15.3mm tall and 3.8mm thick.

For an appliance rated at 700W or less, a 3A fuse should be fitted. 2. For appliances above 700W, a 13A fuse should be fitted. All modern appliances should have the power rating marked on them.
The most common problems found in vacuum cleaners are low suction force, excessive noise, burning smell, vacuum not turn on, and overheating. These issues can be fixed by either cleaning the device or replacing some parts of the device. At times, it is best to seek a professional to fix the cleaner effectively.
There are varying degrees of quality and value when it comes to vacuums; if you paid a lot for the appliance, repairs are likely worth it, but we recommend that you don`t spend more than half of the original price for any repairs.
The rating of an electric fuse should be 5A, so that if the circuit is overloaded above 5A which is the current rating, then electric fuse burns and cuts off the circuit.
Resolution: 250V fuses CANNOT be used in a 600V rated switches, Also, 600V fuses CANNOT be used in 240V rated switches. The Fuses are physically different and would not fit into the switch, so they cannot be used.
Overloaded circuits, short circuits and ground faults are all legitimate reasons why your fuses blow on a regular basis or causes for your fuse box to trip out. Other causes could be a result or ageing or faulty wiring as well as power surges.
Overloaded Circuit

The most common cause of a blown fuse we see as experienced Electricians in Sheffield is when something draws too much power from the circuit. This is most often caused by either too many lights or from using too many plug-in appliances at once.

If your dyson vacuum isn`t turning on, don`t panic – there are a couple possible causes. It could simply be that the vacuum overheated and shut itself off. If that is the case, wait 24 hours and turn it back on. However, another problem with dysons are failed power switches.
When replacing a fuse, always follow the manufacturer`s specifications or match the amperage of the fuse that you`re replacing. Never use a fuse with an amp rating greater or less than that of the circuit wiring. For example, do not use a 20-amp fuse on a circuit with 15-amp wiring.
These 5 Amp / 5A BS1361 type 1 HRC cartridge fuses are used to protect lighting circuits and other small loads. They are used in many older consumer units / fuse-boxes made by Memora / MEM, Hager, Wylex, MK and more.
Some appliances, such as lamps, televisions, computers, fridges and freezers generally require a 3 amp fuse. However washing machines, dishwashers, microwaves, kettles, toasters and irons usually require 13 amp fuses.
5 amp sockets are used on the lighting circuit, meaning they are switched on and off with the light switches in the room, rather than being used like regular plug sockets. They are designed for appliances that take less than a 5 amp current, for example floor lamps, table lamps and fans.
Different types of fuses

Plugs for appliances rated up to about 700 watts should have a 3-amp fuse (coloured red).

A universal motor is typically used as suction motor across vacuum cleaners. The universal motor is a series DC-motor that is specially designed to operate on alternating current (AC) as well as on direct current (DC). Universal motors have high starting torque, operate at high speed, and are lightweight.
If you don`t vacuum your carpet, the dirt will break down carpet fibers and create a breeding ground for dust mites and bacteria. In addition, your home will begin to smell musty from the dirt, mites, and other organisms settling into the fibers.
The average life expectancy of a mid-range vacuum cleaner is about six years. You can fix or replace things like blocked filters, jammed brush rolls, frayed hoses, worn-out stick vac batteries and broken accessories yourself.
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.

Suction problem I have a Hoover Widepath Fold Away, 12 amp motor vacuum cleaner and the problem I am having is every time I vacuum, the vacuum gets clogged up with carpet. I am probably only able to do one stroke then it gets clogged and I have to stop and unclog it or it spits it out on the carpet. This is very frustrating and I don’t get much vacuuming done. Please can you help me. Thank you. Gwen email is [email protected]
ANSWER : Get rid of the carpet its shredding and falling apart.no sence in vacuuming old rotten carpet.or try using a vacuum without a brush roller and just suction

I purchased a brand new Eureka Pet vacuum, sorry don’t know exact name but it the one that has the self cleaning duster on it. Last night I used the vacuum on my carpet, it was working fine until I accidently sucked up the corner of a scarf that was hanging off a couch. I shut the vacuum off, pulled out the scarf and and resumed vacuuming. Much to my dismay the suction on the vacuum had ceased. Can you tell me if there is a reset button on the vacuum? The vacuum does not appear to be damage
ANSWER : If the motor is running, there should be suction. Possible problems depend on whether it’s a canister or upright and are:
.A clog in the hose, UR or canister. Detach hose. Drop small coin in one end and lift hose causing it to roll out the other. If it does, no clog in hose. Drop same coin into hose opening on power head. If it rolls out, no clog in PN.
.Broken fan blades, UR. Needs to be taken to shop for repair/replacement.
.
.A reset button is for use if the motor isn’t running, so won’t have anything to do with the suction.

Dirt devil vacuum cleaner–trouble vacuuming dirt and pet hair on carpeting –is the problem with the spinning brush which contacts the floor,  not contacting the carpeting??  I thought (when I bought this vacuum) that the aforementioned brush was adjustable to various heights of carpeting.  Sometimes, it seems like nothing is being vacuumed up –unless I have just put a new bag on the vacuum… Do I need or can I replace the spinning brush on the bottom of the vacuum so it kicks up and vacuums
ANSWER : Try replacing the belt. Rubber belts stretch out after about a year.

I have a Husqvarna Viking Designer sewing machine. The fuse blew in the machine and I am having trouble finding a replacement fuse. It is a T3.5/250v glass fuse. Please let me know where to find one. I have searched the internet high and low and can’t find one. Radio Shack has a 3.0amp 250v slow blow fuse whick seems to be the right dimensions. Willl that work. Otherwise, I am not sure what to do and can’t afford to take the machine to a repair show. Thank you.
ANSWER : That fuse will work no problem. There is no harm in trying it.
The machine probably requires about 2 amps or less under normal operation.
Being a 3.0 amp slow blow fuse, it will withstand short bursts of extra current when your machine gets temporarily overloaded.

Just make sure the machine is properly lubricated and runs freely. The fuse will definitely blow if your machine should get jammed or something like that.

I think I know where I can score some. Cost of postage only. 🙂

Email me if you like.

I fear the motor has failed on my Electrolux Oxygen EL6988D.

Just six months after the warranty expired, I was vacuuming when it suddenly stopped. There was no blockage in the tube and it wasn’t working hard or long . . . it just stopped.

I looked around the Internet and it appeared that many similar Electrolux units have a fuse. I hoped my problem might just be a blown fuse, so I took the machine apart.

There are two small printed circuit boards, but no fuse. There is an in-line

ANSWER : Hi,
.
.I don’t think you need a new motor, but please stop testing the machine with live power. It’s dangerous and unnecessary. Your tests indicate to me that the motor is fine and your thermal-fuse – I think this is what you referred to as “thermatrol” is blown. I assume you used an ohm-meter to test the continuity across the brushes? If so, and the reading was 0 ohms accross the brushes, then your motor is fine. Also, the 120v reading at the motor terminals with the power on shows that you are getting power to the motor. The reason there is no continuity at the motor terminals is because this circuit is routed through the “thermatrol”. If the thermatrol is open-circuit, i.e. blown there will be no continuity here.
.
.If you need parts, I can probably help you find a supplier, but let’s establish which parts need replacing first! Please confirm the resistance readings from the brushes and we’ll go from there, but no more live testing please, particularly the 120v A/C direct to the motor from the wall socket!
.
.Regards,
.BElectric

I have a Eureka 4870GZ. It turns on, but the brush roller doesn’t move. The belt looks fine. I do have an extra belt and would try replacing the old belt, but I can’t get the old one off the motor shaft or the new one on. I called Eureka customer service. The lady said there’s supposed to be a small space between the motor shaft and the outside edge of the vacuum where I can slip the old belt off and the new one on. I don’t see it. It looks like the motor shaft goes into a recessed place in the
ANSWER : Remove the top cover so that you can access to belt, You’ll find 2 rows of 4 decorative holes on the top cover, In two of the holes you’ll find the screws, Please use a flash light to see in that., Once the screws are removed, you’ll be able to take out the top cover. Pull the belt so that it should rotate the shaft and look for small space in between from where you can take off the old belt and new belt on. remove the agitator from its drive shaft, put new belt in, put the agitator back into place.
