MY VAC KEEPS TURNING OFF AFTER ABOUT 5 MINUTES....I HEARD THAT IT IS MOST LIKELY A DEFECTIVE THERMAL SHUT OFF SWITCH.

I had the same issue and solved it easily.My experience is the same as the March 6th response/ When you push your foot onto the base and then recline the handle, use your toe to gently push the very front of the base down closer to the carpet. This creates a much stronger seal and suction and picks up every bit of dirt easily. If i do not do this extra step the suction is much much less. I tried an experiment with sand that I poured onto my carpet. Initially, I went over the sand 4 times and the dyson 07 would only pick up 50 percent of the sand. I then poured more sand onto the carpet, and this time pushed the front lip down so it was contacting the carpet. This time only two passes were needed to completely **** up all the sand. Not sure why this is not in the manual but it really works. Good Luck!

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.

This could be the switch, but could also be the motor.
The motor has a built in over-current protection device which normally automatically resets itself, but if the motor has had it, it then just cuts out again as soon as you switch it on.
Both the switch and motor are available quite cheaply on eBay, but fitting new ones requires good DIY skills (especially the motor), and some unusual tools (Torx drivers).
Have a look at www.dysonmedic.com which has some great info on repairing your machine, but if you dont feel you can repair it yourself, time to call a vacuum repairer or the Dyson helpline.

does it smell like an electrical burning smell? sounds like your motor has went bad.
