How to Identify and Fix Common Vacuum Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :
If a vacuum motor overheats due to poor airflow, the vacuum will automatically shut off. This is most commonly caused by an air passage that is plugged by hair or dirt. Refer to the leaky hose guide to remove the hose, then inspect for hair or dirt clogs.
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.
How Vacuum Switches Work. Once the switch registers a change in the negative pressure based on the preset sensitivity of the setpoint, the diaphragm of the switch will open or close the attached circuit, turning off or powering on a device. Vacuum switches can be used with NO and NC states.
Why won`t my power unit shut off? Make sure the unit is in the Auto mode and that there is not a hose plugged into a wall valve. Unplug the low volt wire at the side of the unit, if the unit continues to run, the relay in the pc board is faulty and the entire pc board needs to be replaced.
A thermal cut off is a heat-sensitive device that automatically disconnects the power to a vacuum`s motor when the operating temperature exceeds a safe value.
NOTE: If the powerhead is blocked, the motor will switch off automatically. If this occurs, switch off the vacuum cleaner and remove the battery. Remove the blockage, and switch on the cleaner.
The brush is jammed
Should the red warning light appear as shown (see above picture) the brush jammed warning alarm has activated as the brush bar is not spinning freely.
`Tripped` reset systems are the most common reasons for a brushbar not turning, but there are some other less common reasons too. These include: If the bearings on the end of the brushbar have seized, you won`t be able to turn it at all. This will often result in a broken belt as well, so be aware of this.
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.

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.

The shut off switch is stuck to the on position
ANSWER : This sounds like you have an internal problem with the electrical switch. I would recommend you take it to a vacuum dealer who has experience with this model. This is a relatively simple reapir for a pro shop to handle.

Placing the handle of my Dyson DC07 into its upright and locked position causes the beater bar to stop turning. It will not start turning until the handle is first lowered to the working position and the Carpet/Bare knob is moved to the Bare Floor position and then back to the Carpet position. Then the beater bar turns until the handle is placed into the upright position. What might be the problem?
ANSWER : Hi its Darran at Dyson.
The brush control is designed to switch the brush bar off automatically when you stand the machine back into the upright position. It is designed this way to protect any delicate floor surfaces when you have the machine switched on and upright and when you are using the hose.
If the brush control should be in the centre position and move forward to the “on” position when you release the head. If it is not doing this, please contact our Helpline on 0800 298 0298 (UK) or 1866MYDYSON (US).
Kind regards

Hoover Windtunnel On/Off switch will not turn Off…Switch seems to work O.K. when pressed directly but not with handle switch…It will turn on but not off..Cam seems to be intact on switch actuator..How does switch come out? Thanx
ANSWER : Take the handle off, then remove the tool holder, then you can get to the switch. Just has tabs on each side of switch, depress them and push it out. These switches will do this after awhile, replacing them is usually the way to correct the problem.

We have a dyson dc 07 animal the machine was working fine then switched off after returning to the machine minutes later it wouldnt switch on, i removed on off switch cover and used a short piece of wire across the brown wires flicked the wall switch and it worked, aha i thought faulty switch aquired a new one to no avail and now even the short piece of wire trick doesnt work, has the motor died do you think, it wasnt over heating or making strange noises prior to refusing to work
ANSWER : It could be the motor. I’m having to replace the brushes on my DC 05. It appears that you can only get brushes for the YDK motors in the DYSON, not the Panasonic motor. Which might be saying something about the YDK motors. What happens is that the carbon brushes wear down which is normal. However, the contact wire from the brush to its connector is set so that when the brush wears down, the wire is short enough to stop the spring etc from damaging the commutator. The end result is that you get an intermittent operation of the motor before it finally dies.
.I believe all the DYSONs come with the option of both motors and you cannot really tell which motor you have until you take the thing to bits. You also cannot change motors without changing various other parts on the hoover. On my DC 05 the writing on the YDK motor tells you which one it is.
.This website www. tasweb.org ,select the DC 05 option and scroll down tells you how to take the thing to bits. A search on google etc for your DC 07 may give similar results. Best of luck!

I need a Dyson DC 17 Total Clean exploded parts diagream that shows the switch assembly. There are two small springs and a small plastic part that were loose inside the switch assembly. This caused the vacuum to shut off in the full upright position which is the position you use when using the wand.
ANSWER : I don’t have a full diagram for you, but I do have a photo of how they are meant to be assembled:

Vacuum will not shut off
ANSWER : Sounds like you have wires crossed at the switch. The 2 wires coming in go to the center posts, 2 to the power head & 2 to the main motor.

The mechanical off/on in the handle is not working with the electrical on/off switch upon removal of the handle you can cut the machine off by hand but after ensuring the the handle is re-placed in the proper position the machine will not turn off so what new handle or is the rocker switch has worn is now to hard for the mechanical switch to operated
ANSWER : Hi there it’s SmartAlec from NelsonVacuums.com.au here. You are spot on in your diagnosis however i have fixed heaps of these and i have found no way to tell wether its the switch or handle untill you try 1 or the other part.
