How to Identify and Fix Common Vacuum Problems ?

Low voltage is traditionally ran to every inlet in order to switch the suction on/off. The cover plate that fits into the mounting plate has two screws where the low voltage wires are connected. Through either the hose being inserted into the cover plate or a hose handle switch the suction turns on.
Central Vacuum Wiring

For installations, use insulated low voltage wire specifically engineered for appliances such as central vacuum systems. We suggest nothing less than 24-volt, 20-gauge wire, stranded pair. For runs more than 150 feet, 18-gauge wire can be used.

As a central vacuum manufacturer we use the 120 and 240 volt motors. The 120 and 240 motors will not be adversely affected if used with lower voltages. The 120 volt motor will be fine on 110 volts. Likewise, a 240 volt motor will be fine on 220 or 230 volts.
Yes, fiber-optic cables are considered low-voltage cabling. Fiber-optic cables are made from thin strands of glass or plastic that are used to transmit light signals. These signals can carry data, voice, or video signals.
C-wire, or common wire connects low voltage heating systems to thermostats carrying continuous power. Most newer HVAC systems have C-wires making them compatible with smart thermostats.
ln order to operate the central vacuum power unit remotely from inside your home you would need to complete the low-voltage 24v dc wiring.
Central Vacuum Low Voltage Wiring

This specific style of wiring is what is used to operate the unit from the inlet valves placed throughout your home.

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.
Central vacuums can be equipped with either an electrical power brush or an air-driven power brush. The air-driven (or turbine) systems are frequently less expensive since they do not require electrical wires for power to be run to each wall inlet.
Vacuum cleaners are fairly simple machines. They need power to be transmitted to the vacuum to create a suction force that lifts debris. So, the usual areas that cause suction loss include the wrong height setting, stuck rollers, a faulty gasket, a broken vacuum belt, a filled bag, or a clogged hose.
If there is no or low suction, then the clog is in the hose. You can remove the clog by running a long, stiff object through the hose, such as a butter knife, starting at the wall end. Another option would be to reverse the airflow through the hose by connecting the handle end into the intake on the main unit.
If you don`t have access to various colored wires, at a minimum is red for all low voltages, black for common and green for ground.
Yes it is still dangerous. People can be electrocuted by coming into contact with 100-200 volts and there have been reports of injuries or death resulting from being shocked with as little as 42 volts.
Is it safe to use speaker wire for the built in vacuum. Answer: You can use any 20 or 18 gauge wire and we recommend it be stranded, not solid. Speaker wire is expensive, but if you have it, use it.
Will a dedicated electrical circuit be required for a central vacuum power unit installation? Yes. It must be either a 15 amp or 20 amp circuit depending on the specific power unit you are installing.
US AC power circuit wiring color codes

The protective ground is green or green with yellow stripe. The neutral is white, the hot (live or active) single phase wires are black , and red in the case of a second active. Three-phase lines are red, black, and blue.

The voltage of 24VAC is primarily used for two purposes: the first is control, such as in door bells, control panels and thermostats. The other is to supply operating power, such as in door bells, irrigation valves, rotation encoders, low voltage lighting systems and CCTV cameras.
Typically, a VDC output power supply is a simple AC-to-DC converter that has a power supply voltage of 110 or 220 VAC, and it converts this into a 3V, 5V, 9V, 12V, or 24 VDC. Overall, these VDC output power supplies are available in a variety of configurations, sizes, and output levels.
Battery voltage: the higher the battery voltage, the more powerful the vacuum cleaner absorbs the dirt.
Some people confuse volts with the power rating of a vacuum. Volts is related to the battery being used and does not affect the suction ability of the vacuum.
The power unit is typically located in a garage, basement or utility room.
There are many different models, designs and sizes for vacuum cleaners, ranging from small and portable to large industrial models. A regular sized household vacuum cleaner will use between 500 and 3000 watts of energy, an average best selling model will use around 1400 watts.
Simply attach an air-driven beater brush to the end of the wand and turn on the suction. The air from the vacuum pushes the brush through a turbine. You`ll need an electric hose hooked into an electrical outlet or an electrified central vacuum inlet to use an electric power brush.

My home has a central vacuum system hook-up but no vacuum installed. My friend upgraded his central system and gave me his Eureka Mega Boss central vacuum system and the accessories, including the pow
ANSWER : The power head requires 120 Volts. Some hoses have a receptacle in the handle for the power head plug, and the hose has a cord at the wall inlet end that plugs into a receptacle. Some hoses have a plug at the wall inlet end that plugs into a 120Volt receptacle built into the inlet. The hose plugs into this receptacle when you push the hose into the inlet. The power for this built-in receptacle is wired with line voltage when the system is installed.

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.

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.

Electrolux Epic 6500SR Full Bag sensor working, Does not Reset properly
ANSWER : The problem was a sticking switch that was not being reset. The vacuum on/off switch mechanism is comprised of two switches. One is the main switch that turns the vacuum on and off. The second is a shut off switch that gets tripped when the full bag sensor is engaged. This second switch is supposed to get reset when you push the on/off switch on the outside of the machine. The full bag shutoff switch was stiff and it, therefore, was taking a couple of presses of the on/off switch to move the shutoff switch back into the running position.
