I have a Dyson vacuum cleaner with a burnt out motor. I assume that a
build up of dust on the air intake filter caused it to overheat.

However, before fitting the horribly expensive replacement is there
anything else that *could* have caused the burn out?

Could a faulty motor run capacitor cause it to overheat for example?

Has anyone else noticed the poor build quality/bad design of Dyson
cleaners?
