Motor/Fan does not run. I have removed and taken the top of the canister plastic motor housing apart and tested for power. I have power through the cord to the switch and power from the switch to the two wire terminals. I have not removed the motor. Looks like I will need special tools to take out the motor. The Vac looks almost new. It has been setting for several years. What do you think?

Upright or canister? On the canister type, the unit has to be taken completely apart by separating the top and bottom and removing several screws to get inside to find the motor. A search using your model number will normally reveal a youtube video showing you how.

The fan / motor is not designed to be taken apart.

Is there suction at the hose? If not it is either blocked or the suction fan is broken. If there is, then there is a blockage in the pickup section, something is lodged across the channel after the brushes and before the place where the hose plugs in.

I think there is a safety switch to prevent it from running with the canister out so hard to check for suction at the top of the motor/suction fan. Make sure nothing is over that part under the canister too! If you can figure out how to bypass the safety switch (if there is one), you should have good suction where the canister sets on top of the motor base.

Most Hoover uprights do not have fuse. Some canisters doe but it is a thermal shutoff. When the vac overheats and cools down it restarts on its own.
You very likly have motor damage, but if lucky you could have an obstruction in the fan causing a jam. Do not attempt to run again.Lift the lid off the vac and see if the drive shaft for the belt will turn. If not motor will need to be removed and fan housing and intake area inspected. If the motor shaft turns and you hear scratching or clicking, the carbon brushes are likely damaged often requiring a replacement motor. If the fan is jammed you will need to dismantle the fan housing. Remove the two motor clamps and there will be four screws on the side of the housing to release the fan cover. The fan should rotate freely in your hand.

Hi,

I've never worked on a DC11 but have worked on several types of Dyson uprights. The following may or may not be relevant to the DC11 but may give you a few clues.

On the uprights I've worked on, if you remove the dust canister, underneath it is a clip-on cover with what's known as a post motor filter under it. This varies between models from a simple fibre pad, to a plastic encased paper filter very similar to the one that goes in the top of the dust canister. Having removed the clip-on cover / pad / filter, there should be a few more screws that when released will allow the motor housing to be taken apart.

The site www.dysonmedic.com is excellent, but doesn't yet cover the DC11.

Incidentally, I've just repaired my fathers DC07 which appeared at first to be a brushes problem. When I got it apart, it became obvious that the motor armature had a worsening fault whereby it was overheating so badly the over-current trip on the motor kept cutting out. The overheating was so bad that the bottom of the post motor filter was actually burnt !
Searching on eBay, I found a complete replacement motor for £18 inc p&p, but no listing for brushes. You may therefore find a) it isnt the brushes and b) you cant buy the brushes separately anyway.

Good luck !

HOW TO OPEN MIELE 251 VACCUUM: 1-Unplug from wall and disconnect power cord 2-Remove black switch panel at back of top panel: A-Use Phillips screwdriver, remove two silver screws visible between back of hinged top door and front of black switch panel
B-Push back of the panel down while pushing it forward (towards front of machine). There are two plastic notches and clips which are tightly fit together that you need to separate.
Once it releases, push it a bit more towards the front of the machine and lift off panel. It has wires connecting it to the main body so it will not remove completely.
C-Be careful not to lose the springs that simply sit inside of two plastic channels, one under each of the two switches. These are required for your witches to operate properly.
3-Locate screw at bottom of deep rectangular hole now revealed (under former location of black switch panels). Unscrew using Phillips screwdriver. 4-Open hinged top panel. Locate two silver screws, one on each side of main housing. Unscrew using Phillips screwdriver. 5-This will let you lift off the whole top assembly, door and main housing, revealing the plastic chassis and the motor unit within.
You now have access to the motor, wiring connector harnesses, circuit board and the cord reel.

You will have to take most of the vacuum apart to replace your fan.
First; remove the handle assembly by pressing the button on the front of it near the base. Remove the bag unit by twisting the rear of the emptor away from the body, and remove the front nozzle assembly by rotating the belt removal part to the "off" position and flipping the latch at the top of the nozzle.

There's a screw on the very back above the self propel select, and one on the top of the plastic where the cord attaches, removal of these will let you remove the rear plastic piece. Then there will be two more screws above the main power switch, and two on the front of the housing under the headlight. Remove the power cord, and then you can lift the rear housing from the main body.
Now you can remove the screws from the front of the fan housing; I believe there are five. Make sure you keep track which screws came from which position, because they are all different sizes.
To remove the front of the fan housing, put a flat-head screwdriver in the gap at the top to the side of the headlight assembly and pry it apart.
To get the motor pulley off you'll want to grip the pulley with a pair of vice grips, and use a wrench to hold on to the motor shaft in the rear of the machine. Look at the shaft that runs to the rear from the armature, and you should be able to locate a flat section which will allow you to grip it with a wrench... I do not recall the exact size, but there is a standard one that fits it perfectly. The pulley can then be removed. Note that it is reverse-threaded. Keep in mind that you will need to replace all the little plastic washers and rubber gaskets and things that are on the shaft with the fan. They are usually included with the Kirby fan kit, but if not make sure you find some before attempting the repair.
Before reassembly, you'll want to apply a thin layer of adhesive around the edge of the fan housing, making sure you don't glue the safety switch on the front into place.

Reassembly is the reverse of disassembly.

Good luck.

Kenmore Whispertone Model 26512690 PowerMate Brush motor does not run. The machine has no suction coming from the Power Mate Brush. However, I do have power in the main machine.

How do i replace the

How do i replace the fan blade assembly which are broken in my eureka model the boss
thank you

Hello,
I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
There are 2 different models of the boss by Eureka – there is a standard old style upright that the belt that the belt would unscrew from the bottom of the motor and you would have to remove the top of the vacuum cover to remove the main motor and gasket assm, and then the fan has a reverse thread on the plastic fan and you would unscrew the fan after removing the belt pulley. Then you would screw on the new fan, belt pulley, replace the gasket and re-install the motor. If you have a new style with a side mount motor you would remove the top cover, the motor would be in there sideways, un-screw the motor, remove the silver tape around the fan housing and un-screw the fan housing – same as above un-screw the fan from the motor, there is a nut on the end of the fan holding that on – (remember, the fan has a reverse thread) re-install the fan. Then the fan housing, replace the silver tape, and then screw down the motor and replace the top cover, then you can test. As always free to contact your local vacuum dealer in your area in the yellow pages or contact your Eureka factory manufacturer listed below:

These motors have a fuse incorporated in the field winding and it sounds like that blew. These motors sometimes overheat at the front bearing and the bearing will melt into the plastic housing. This will cause the fuse to blow. It sounds like that's your problem. You can remove the motor by removing the three screws on the bottom of the powerhead and then check the front bearing for any bubbling or blistering in the plastic housing. The shaft of the motor should turn easily.
