Hoover Vortex 2000 001, had started making a burning smell, I suspected the carbon brushes. This prooved to be the case one of them had seized in its holder. Freed that off, tested vacuum on bench all OK and ran without the smell of arcing.
Put it all back together again, pulled out power lead and machine promptly fell over. Powered up and device showed no sign of life whatsoever.
Took the Vortex apart again and checked, retractable power lead connections, power switch and carbon brush connections for continuity. All test OK on buzzer test.
Any and all further ideas welcomed!
Kind regards FireintheHearthRe: It started with a burning smell…

Very likely the armature is cooked. Poor brush connections cause arcing but burning smells almost always point to the armature or field coils….not good! 🙁
Re: It started with a burning smell…
Thanks for response Martin.
Just some sort of law governing the initial sucessful running on the bench then?I think I can get a new motor unit for about the £36 mark…or does anyone know better?
Regards FireinthehearthRe: It started with a burning smell…
The new motor has now been received and installed.
Ran it up on bench, all ok.Put it all back together…nothing!
Considering that there are very few parts to this machine, motor, automatic resetting thermal cutout, power switch and a capacitor/resistor filter does anyone have an idea as to the culprit?
If the motor overheats, then the cutout operates.
Why would a brand new motor overheat??
Could the cutout operate below its set temp?Does anyone know the failure conditions delivered by a faulty capacitor/resistor filter?
Redfaced this end!!!
Re: It started with a burning smell…
Does anyone know how to source the Capacitor/filter part for this Hoover Cleaner?
It’s a 0.15uF + 1MegOhm, wire ended device.Similarly the Auto-resetting Thermal Cutout?

Re: It started with a burning smell…
Ok so I have now replaced the suppression capacitor harness and the thermal cutout harness.
Still the fault persists.
Took the switch out of circuit.
The fault still persists.
I have now officially gone insane as there is no original part left in this machine…can anyone recommend a reasonably priced sanitorium for a good long rest in a darkened room!Re: It started with a burning smell…
Before you phone The Samaritans it couldn’t be anything to do with this could it…….
