I have a Dyson 21 for the past three years and loved it until recently. The motorhead keeps shutting off. So I cleaned the filer, let it dry the 12 hours, and even bought a new motor head for $150. I tested it today and it still keeps shutting off. I checked the hose for obstructions (which there were none), made sure everything was cleaned and NOW I am at a loss. What else can I do?????

Hi.
I think you are looking at replacing the motor with a new one.

Hi,
Lie machine on its side pull back handle as if vacuuming & switch on (KEEP YOUR FINGERS & ANY LOOSE CLOTHING CLEAR OF BRUSH ROLLER)
Brush should spin if it doesnt ensure clutch control knob on side of machine is in drive position if it isnt rotate knob by hand to drive brush should now spin.
If it doesnt & your machine has A clutch either clutch will need replacing or belts will need replacing.
Manuals are available to replace belts & remove the clutch from this site http://dysonmanuals.llc.nu/index.htm
SOURCE: Overheating Dyson DC07
Many devices including this one have what's known as a thermal cut out.
It is there for obvious safety reasons and prevents the temperature in
the locality of the cut out from exceeding a pre-defined value.
Some of them require you to press a reset button in order to switch the
power back on and other types simply reconnect the electricity supply
when the temperature returns to normal (safe) operating limits.
The Dyson DC07 has a thermal cut out located close to the motor and it is of the "self resetting" type.
If your vacuum cleaner switches off after a few minutes the most
probable cause (there can be others) is the thermal cut out has
operated.
The first and most important thing to do is to establish why it has
operated.... If the airflow around the motor has become restricted then
it will not be being sufficiently cooled and so it will have cut out
correctly. However, thermal cut outs are often quite crude internally
and it is not uncommon for them to start cutting out at too low a
temperature. So...
Here's what to do...
(some tools may be required to complete the following so read the entire
procedure before starting. Please note this is not an absolute guide if
you need really foolproof step by step instructions... buy a manual!
But this should help)
Check all these parts for blockages/clogging before continuing...
There are now only two areas left that I know of which may cause
further blockages. One is the "whole of life filter" located under the
dust bin and the other one is inside each of those seven little cones
(cyclonic chambers) at the top of the dust bin (root 8 cyclone is
usually written on one of them). The following will require some tools
and some common sense...
If none of this revealed anything very positive... Its time to open up and inspect the motor casing/thermal cut out.
**** WARNING**** The next section requires someone who is technically
minded, has fiddly fingers patience and a basic understanding of
typical plastic goods assembly techniques. As I am not including
photo's the descriptions given can only be considered as pointers to
how to do it (I'm not writing a Haynes manual here! So if you are a cak
handed clot with little or no patience and a tendency to resort to ever
bigger hammers - take the vacuum cleaner to an independent repair shop
- explain the symptoms, tell them what you have done so far and leave it
to them!!
NB. NEVER remove or bypass the cut out. this really could be very dangerous!
I hope this is of some help... Regards to all.

The Dyson site has a help section where you can read how to take the unit apart to unblock it. Maybe your solution can be found there.
Hard to tell since you didn't say what the part is.
SOURCE: My dyson DC17 will not turn on unless the handle
Not sure if I can help, but I'll try. The DC17 has two motors: the vacuum motor and a separate motor for the brush bar. It is normal that the brush motor works only when the handle is pulled back in the vacuuming position - that's the way it's made. So, when you say "my DC17 won't turn on", I'm not sure if you mean the vac motor, the brush motor, or both. If the vacuum motor won't turn on, then you've got a problem I can't help you with.
As for no suction through the hose, I have to ask... are you sure your vacuum motor is working at all? Even with the hose stored away, the machine still relies on suction through that hose. If you're sure the motor is working, then either you've got a blockage that you haven't yet found (there's at least one inspection port, a sort of U tube at bottom right of machine, that you need to check), or it could be that you've got a hole in the flexible hose (which opens only when the hose is extended).
Sorry if this is a bit garbled, but I'm puzzled by your problem. If you want to come back with more details I'll try again for you!
