Author Topic: DC14 short circuited (Read 6810 times)

Hi,
I have purchased a new motor as my last one which I have replaced 6 months ago stopped working.
after installing it unfortunately it didn't solve the problem. I've managed to start it for a second and then it stopped. I'm wondering whether the problem is short circuiting rather than the motor as I've tried the old motor again and it caused the same problem (worked for a second and stopped).
Any ideas what could short-circuit the DC14? Many thanks for any suggestions.

If you hold the switch down, does it stay running fine?

I bet (virtual) money on a switch fault...

Thanks for the reply,
When I hold the switch down it works for a second and then the fuse in the electric board short-circuits...
The problem started after the DC14 worked hard for 20min in a dusty area.
Cheers!

Aaah damn, glad I didnt bet real money...

Theres not too much to troubleshoot luckily on a 14. Coyld you crimp up a scrap of known working cable and try? Apart from that theres the spinal cable, but you would have had to really yank it to break that.

Are the motor wires the right way round? Red to brown, blue to black.

Failing that, how much was your motor? Does it have a thermal cutout module like the original?

yes, he motor wires are the right way round.
the motor which I bought is the following:

YDK (YV) Motor Dyson DC04 DC07 DC14 DC27 DC33
- Choose Your Motor: Premium Motor (The o.. YDK (YV) Standard Upright Motor 1 £29.99

not sure if it has a thermal cutout module. How would I be able to check that?

Do you think it could still be the switch ot the cable which might be short-circuiting?

Many thanks!

Its possible it could be the switch. Either get a new switch, or if you have crimps and a crimping tool handy, crimp the cables together without the switch.

(certainly dont put the live connectors together and very very tightly wrap it with insulation tape for a brief test fire...)

That motor doesnt sound like it is so cheap its dead on arrival. Thermal cutout is a module (usually white holding bracket and black square inside thst) that sits on the side of the motor near where the main wires come out.

If youve got the time and, avain, spare cable and crimps, strip her back to the motor, feed the new length of wire through the spine cable route and 2 female crimp it to the motor, pjt back together so it holds steady (can get away with just screwing the motor housing back together) incase it fires up and shoots across the room...

Either way, bypass the switch. The main cable wouldnt go unless its visibly damaged, and ive never known a dc14 to breal itself by the machine like the dc04s did!

That is the good one - they work.

This could also be a short in the mains lead.

Hi guys,
Thanks for the advice.
I've ordered a switch and will try and see if it solves the problem (hopefully!)

Will keep you updated once I received it.

Hopefully it will.

I feel a bit more confident now, since on yours the motor does briefly fire before stopping as I obtained a dead DC14 last night, but my one is fully dead, not even a new switch cured it...

Can you hear/feel the switch click on and off internally? If you can't I'd be even more confident its the switch, they stop working when they go mushy...
