Marathon Champion 3 Micromotor - Variable speed stopped working
hello, I have a marathon champion 3 micromotor and yesterday the variable speed suddenly stopped working. When I turn it on, it seems to be at the highest speed setting, noticeable blowing of air from the handpiece fan, which it never did before. I never really used the highest setting before, probably max about 1/3 to nearly half way in terms on the dial.
Wondering if anyone else with this micromotor has had the same issue, and whether it was the handpiece or the control unit itself that was the problem? Annoyingly it fell out of 1yr warranty last month.
Thanks
