How to Identify and Fix Common Vacuum Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :
The suction motor creates vacuum pressure and suction by rotating a motor fan. The impeller rotates at an incredibly high speed of about 30,000 to 35,000 RPM. A suction motor`s power is measured by multiplying the rate of air flow and the vacuum pressure, which induces air flow from the brush through the hose.
Conventional vacuum cleaners mainly use universal motors powered by a mains supply. Nowadays, brushless DC (BLDC) motors powered by a DC power source are increasingly used for cordless cleaners. BLDC motors are available with three-phase and single-phase configurations, which are controlled in different manners.
Fixing a broken or damaged vacuum power cord is another common vacuum repair that do-it-yourself-ers can easily handle at home. Home repairs on vacuums, tools, outdoor equipment, and other appliances can save you a truckload of money at the repair shop, and anyone can take on simple repairs like this one.
UNITS THAT EMPTY FROM THE TOP: The motors are on the bottom of the vacuum unit. Remove the unit from the wall, turn it upside down, and open the bottom or bottom section to reveal the motor. Each motor has two or three wires that may run to other wires, relay, or mini-breaker.
As for the commercial sector, almost every central vacuum operate with two motors.
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).
Central Vacuum Wiring
We suggest nothing less than 24-volt, 20-gauge wire, stranded pair. For runs more than 150 feet, 18-gauge wire can be used.
Some appliances, such as vacuum cleaners and electric drills, do not have an earth wire. This is because they have plastic casings, or they have been designed so that the live wire cannot touch the casing.
A majority of the vacuums are manufactured from a plastic material. Although these units can generate static energy, this energy does not pose any additional risk to the user compared with other static discharge sources. Since many of the vacuums are based on a plastic material, grounding is impossible.
A vacuum engine (also called flame-licker engine, flame-engine, flame-dancer) derives its force from air pressure against one side of the piston, which has a partial vacuum on the other side of it.
In general, standard motors will not survive in a vacuum of 10–4 Torr or lower for very long. The primary reason is that the lubricants and the insulation materials will evaporate, a phenomenon known as outgassing.
If all you hear from the vacuum unit is a click at the when you try to start the vacuum motor from inside the house, then the motor in the unit is dead and has to be replaced. A strong odor from the shellac, which coats the copper coil windings, is an indicator that the motor is about to or has burnt out.
Vacuum cleaner motors can typically do 10,000 RPM with plenty of torque.
If the wire has been completely cut or it`s hanging on by a few strands of copper wire and you`re skilled with a soldering iron you can repair the cut wire yourself. Repairing damaged wiring is easy and it can save you time and money, but care must be taken any time a soldering iron is used.
The green wire is the ground wire, the white wire is the neutral wire, and the black wire is the hot wire. Light-duty interior extension cords often lack the ground wire, but if a ground wire is present, be sure to connect it.
Here`s a rundown of electrical wires: The black wire is the “hot” wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel.
The black wire, which is hot and carries the electricity, goes to the golden brass screw. The white wire is neutral and hooks around the silver screw. The green wire goes to the ground screw.
If a cord is frayed, damaged, or worn away then the wires inside are exposed. This means you are more likely to come into contact with the wires, which can cause an electric shock.
Universal motor is generally used for suction in vacuum cleaners. It is a series DC-motor that is designed to operate on AC as well as on DC. These motors are used because they have high starting torque, operates at high speed, and are light weighted , easy mobility.
A DC motor is defined as a class of electrical motors that convert direct current electrical energy into mechanical energy. From the above definition, we can conclude that any electric motor that is operated using direct current or DC is called a DC motor.
The most obvious difference is the type of current each motor turns into energy, alternating current in the case of AC motors, and direct current in the case of DC motors. AC motors are known for their increased power output and efficiency, while DC motors are prized for their speed control and output range.
Most vacuum machines are equipped with motors that use anything from 500 to 3000 watts of electricity, with the typical unit using around 1,400 watts.
Most universal outlets found in households have a standard voltage of 120. Therefore, most vacuum cleaners are designed to handle 120 volts. If you find an upright or canister vacuum with a voltage rating lower than 120, it is not going to work with your inlet.
It is because the armature and field windings are connected in series that a universal motor can operate with either DC or AC supply.

I purchased a utilitech 7-day digital in-wall timer #0141224. My house wires are two black wires and a green ground wire. The new timer has a w,g, r, and b, wires. My question is what wires do I connect. I found the black power wire from the house. I have no white wire in the switch box. Where would the red wire go? Thank you
ANSWER : Hi!!.
..
..
- .
- The Green wire goes to ground,
- The White wire is the neutral. (in this case is used to supply power to the clock.)
- The Black wire will have to be connected to the incoming black hot wire and,
- The Red wire will go to the black wire going to the light.

.
.In order for the timer to work, you’ll need to run a Neutral wire from a nearby outlet into the switch box to power the timer..
.Good Luck!! A HELPFUL – 4 THUMBS – rating for this solution would be greatly appreciated. Thank you for using FixYa.

Local vacuum repair shop replaced motor in Oreck XL 2600HH and now the lights blow out immediately upon powering up the machine. I believe the wires for the lights were mis-wired to the terminal blades on the motor housing. is there a wiring diagram available to properly connect the wires to the motor housing?
ANSWER : Hello. if this repair just occurred return this vacuum to that repair shop as they owe you a valid repair. I agree that they caused the lights blowing out problem. They must repair this for no charge. If you work on it yourself they will blame you. Joe

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.

I purchased a Eureka C4910 last year and have a question that I am hoping you can answer.
There are two motor actions with this vacuum, 1) the vacuum suction, and 2) the beater bar. The action of the beater bar is that motor is supposed to automatically shut off when the handle is in the complete vertical position assuming the vacuum is stationary, but then turn on when the handle is tilted toward the floor, assuming the vacuum is moving back and forth.
The beater bar motor turn-on mechan
ANSWER : Good day!
Normally when the motor is easily moved back and forth means that it have a proper lubrication,proper alignment and no clogs.
When the motor and the belt is OK the problem could be on electrical wiring and switch.
If found electrical switch burned out you need to replaced it because when the switch is burn the contact of that switch is open even you turn it ON.that’s why the motor is not function because the voltage is not pass through the circuit because of open switch.You need to replaced it.
And check some fuses if any and other burned electrical wire.Replaced it also.
Thank you and don’t forget to rate my answer.

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.
