Rebuilt Motor Going Bad
have a MK-X model, replace motor with rebuilt one last year. since then breaker button keeps popping-out after 10 minutes or so. brought it back to local vacuum dealer, worked fine there. once home worked fine the first few times but start doing the same again. Originally brought the unit to the shop for a transformer replacement, figured the motor bearing was on its last leg, thought might as well...then hum!
Hello Jocelyn, our opinion is to get new motors not rebuild. The most likely reason for the inconsistent breaker issues it the fact you moved the machine around. Many times that repositions the motor brush just a bit and it runs fine. If you go shake and bump the machine it may work better for awhile again, but you will have to replace the motor eventually.
