The motor thermal protection keeps tripping after a few minutes.I have stripped and checked all the filters and tubes are clean but still keeps tripping .Any ideas ?.Graham
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.
Hi Graham. Remove waste bin unit from machine & run machine does it now cut out or run ok.
1) Ok remove side filter & do test again.
2) Does the motor slow down & pick up speed with a popping noise ?
If after doing test 1) machine still cuts out then the problem lies at motor end of machine this could be warn carbon brushes, faulty thermal cut out, or motor breaking down.
If after doing test 1) machine now runs ok purchase new premotor filter.
If the motor is making strange noises & popping sounds remove post motor filter this is situated under the waste bin, look at filter has it got scorch marks on it if yes you will need a new motor.
If its just black with carbon dust thats fine
you are probably now looking at replacing carbon brushes or thermal cut out which is reletively simple job.
Should you find that the problem lies with motor, brushes, thermal cut out I can supply spare parts & manuals that tell you how to strip machine down.

Usually answered in minutes!
Yes , have done this and still cuts out after a few minutes.
Yes, we have the same problem. I have removed the switch and replaced with new. this seemed to be the answer but again after about 5 minutes the machine cut out I'm not sure but it seems there must be a thermal cut out,Where is this on the mchine? Can you help ? Regards Brian
Have tested and cleaned all filters and parts in various configurations.
The problem is motor just runs hot from the effort of doing its job. With minimum attachments it holds out, but even a filter casing (empty of filter) is enough to cause it to run hot and result in a thermal trip out.
Yes my Dyson DC07 does the same thing. After 5-10 minutes it cuts out also even after cleaning out the filter. Has anyone found a good solution?
blowing fuses
my dyson also cuts out after 10-15 minutes of use. after down time of 5 minutes vaccuum works again for maybe 5 minutes. all filters are clean etc. took vaccuum to repair service and they ripped me for 100.00. still having same problem 6 months later. TIME TO BUY NEW ????
