How to Identify and Fix Common Vacuum Problems ?

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

Another reason the vacuum is not turning on may be that the circuit breaker may have tripped. Check the breaker on the unit and if it continues to fail it usually means the motor is going bad. Another reason can be the bad signal from the unit to the wall inlet.
The most likely cause is incorrect wiring to your wall valve inlets. Disengage one of the system wires on the front of your power unit and if the system shuts down then you need to verify the wiring to your wall valve inlets is correct. If the problem persists call Broan-NuTone Technical Support at 888-336-6151.
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.
Overheated Motor

If your vacuum was working fine and then suddenly shut off, it may have overheated. Most vacuums are equipped with a thermal protector safety switch that won`t allow the motor to run when it becomes overheated. You will need to wait for 30 minutes to 2 hours, depending on your machine, to try again.

If your vacuum cleaner keeps turning off, this could be due to the following reasons: Blockages – check the hose and head for any obstructions. Filter – always check your filters, if these are clogged this could be causing the vacuum cleaner to work harder and lose suction power.
the vacuum system may be dirty, the pumping line may be restricted or too small in diameter, the pump may be dirty or with too little capacity, the pumping speed may be restricted due to other causes.
To fix a clog in the hose, feed one end into a garbage bag, and poke the other end with the back of a mop pole, until you push the clog material out into the garbage bag. To fix a clog in the vacuum, whether it is a canister or bag, use your finger to feel for a clog. Pull as much of it out as you can and discard.
While different factors affect how long a system lasts, many central vacuums can last 20-30 years, or even longer, depending on how often they are used.
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.
The most common reason for vacuum motors failing is overheating. Most `dry` vacuums have a flow-though motor. These motors use the air they have sucked up the dust with, to cool themselves. When there is a blockage, flow-though motors are unable to cool themselves due to the lack of airflow.
Most air conditioning units are equipped with a reset button. These buttons tend to be red and quite small. If you`re having a tough time finding it, consult your owner`s manual.
Alternatively called the reset switch, the reset button allows devices that utilize it, such as a computer or peripheral to be rebooted. Usually, the button is on the front of the device, next to or near the power button.
The suction power is to be measured at the end of the tube of a complete vacuum cleaner (i.e. with tube, hose and filters – but without nozzle). Some manufacturers show the results from measurements made at the suction of the actual vacuum cleaner.
Connect a tachometer and vacuum gauge to a none regulated vacuum source on the engine. Disconnect and plug fuel vapor canister vacuum lines. Start engine and run the engine until it reaches normal operating temperature. Note the vacuum gauge reading and any variations in the pointer movement at idle and 2000 RPM.
If you hear a clicking sound, one or both of the motors have failed and should be replaced. If no clicking sound, the relay has failed and should be replaced.
Check Your Breaker Box

Your well pump may have stopped working due to a lack of power. Sometimes resetting a breaker or replacing a fuse affected by a power surge or brownout can fix this. If the well pump circuit breaker has tripped, the well pump itself may be failing.

The pump is not producing the rated flow or head:

The clearance between the impeller and casing is excessive – adjust the impeller clearance. The suction head is insufficient – ensure the suction line valve is fully open and the line unobstructed. If the impeller is worn or broken – inspect and replace.

Power Usage

The amount of power used by a central vacuum system is roughly the same as that of a portable vacuum cleaner. Yet, it has 3 to 5 times the power of a portable vacuum cleaner. You are getting more suction power, which translates into more efficient cleaning, at no extra energy usage.

Yes, you can use standard, plumbing PVC found at any hardware store to run the pipes for your central vacuum system. It not only saves you time not having to scour the planet for hard-to-find central vacuum piping, it also saves you money because standard plumbing PVC is so much more affordable.
Any fine dust remaining in the filter can usually be removed with a gentle rinse under a cold tap – hold the filter under the running water until the water runs clear. You shouldn`t need to use any detergent – just water.
Loose connections will cause your vacuum cleaner to lose suction. Make sure that the dust container, the hose, the tube and the brush are all attached properly. If the problem continues, your vacuum cleaner might have a technical problem. If you suspect this to be the case, contact an authorised service agent.
Check the power unit reset button located above the power cord. Pressing the button should restore operation. NOTE: The reset button is located on the upper left-hand side of the unit where the low voltage wires connect to the unit. It is most noticeable when popped out after the breaker has been tripped.

I need a relay board for a Nutone CV 450 12.6 amp dual motor vacumn unit. Where can I locate one? Part #??? Unit will run by itself, then shut off. Unit wll not run at all. It has a mind of its own. Crossed a couple of wires on one of the relays and the unit runs smooth as silk. I assume its the relay, but can’t locate part number.
ANSWER : Why not just replace the relay? Part number 1094117…

Electrolux Centralux I have a Electrolux Centralux. When I plug the hose in at one of the wall outlets the motor will not start. If I go to the motor and slap the unit it will start…..then…it will not stop unless I unplug the power cord to the motor. If I plug the power cord back in, the unit will not restart until I slap the motor unit again. The unit has only been used 20 – 30 times. Any suggestions?? Thanks, Bruce
ANSWER : I dont know if you had your unit looked at yet but it sounds like the Power module is going. I repair the machines so I know some of the work.

I have an Easy-Flo central vac unit. The handle on the electric hose has a switch on the handle. With the switch on ”O” in the center, it’s off. On the left, is the ”I” position. The vacuum runs but the power brush doesn’t. On the right is the ”II” position. The switch won’t flip that way. It feels stuck. It feels as if there is something underneath of it that won’t let it push that direction. I have the switch out of the handle, but I can’t seem to get the actual black casing around the
ANSWER : Switches are not usually designed to be dissembled.
I would strongly suggest that you dont take the switch apart. you are better off getting a new one. then if you feel like it you can take the old switch apart and if it dosnt work you still have a new switch. if you decide to dissemble the old switch be vary careful there are very small parts in there that will fall out. and most of the time the casing will crack when you pry it apart.

Good luck
STITCHES

I have Nutone VX550C. Motor runs intermittently (cycles on and off rapidly–the light on the handle is blinking furiously) when I use the on/off switch on the hose. This happens at all of the wall connectors, so suggests a hose contact problem. Motor runs continuously when I turn it on at the switch on the wall unit.
ANSWER : The unit does have a switchs the PVC outlets, and it sounds like the hose mech to operate the switches is broken, and intermittently making contact. A replacement hose would likely fix the problem. Looked them up on the net, and they’re not cheap. Here’s one site that offers free shipping, at least:

My lux 7000 has a new bag but when i start to use it with the power unit or without the unit shut’s it self off i can reset the lites or the motor if you will by clicking the on off switch 4or 5 times and i’m ready to go again untill you start to work and off it goes you can repeat the switch thing as long as u want, it just won’t let u vacuum ,it turn’s it self off .I blew it all out but found nothing in it. if u don’t try to vacuum it will run as long as u want to listen to it. Can you
ANSWER : Have you replace the afterfilter? It may also cause this if rather dirty. It’s located under the tool caddy/air diffuser on the back half of the machine.
.Try this: Disconnect hose, turn on vacuum. Does it continue running? If so, place palm of hand over intake. Does it shut off? If so, it’s probably a broken or worn out “control valve assembly” (CVA). Or a tube connecting to it could be clogged and simply needs cleaned out. This is very common in vacuums that have had generic or “made to fit” bags used in them. Either way, this is a job for Supertech.
.Take your vacuum to a nearby Aerus Electrolux authorized store and have the service tech check it out, provide an estimate for repair, and then repair it. It’s a good idea to have the interior cleaned at this time, and doesn’t cost a lot more. It will get rid of the dust in and around the motor that could shorten the life of the motor.

The motor won’t run. There was interupted running
ANSWER : What model#? Plus check to see if their is a reset switch, sometimes on hoover the switches do go bad, but if the unit is new could be still under warranty

Nutone model cv-350 vacuum motor will not shut off. I have to unplug system in garage. I disconnected wire to house vacuum inlets and motor is still running. There must be a reset on the motor. I have turned the external switch on and off and still no help.
ANSWER : Mine is the same, and it is the relay welding itself closed. The relay is switched by the low-voltage wiring that connects to the vacuum outlets, and it switches the motor on and off. Mine was welded in the energized position. I have cleaned and filed the contacts on the relay, and that solved the problem for about a week. I suspect the relay contacts were plated, or a worn motor is drawing a little too much current (it is several decades old at this point).

Our dustbuster (dont’ have model number with me-sorry) won’t turn off when I pull back on the switch handle. I disassembled the unit and realize that the tab on the switch handle that pulls back on the internal switch handle to turn it off is not strong enough for its simple task. Does B&D have a proper replacement part?
ANSWER : If you can provide a model number, I can check availability of the switch and can either order it for you, or supply the B&D part number and you can order it from most local vacuum shops in your area or from Black & Decker direct online: http://www.blackanddeckerservicenet.com/servicenet_home.aspx?AspxAutoDetectCookieSupport=1
