So you know electric motors and stuff? (Internet, component)

Kitchenaid hand mixer has developed an oops.

Model KHM9PWH2

First, I know squat about electric motors.

I opened it up and when I start it it comes right up for a second or two, there is an arc between the two brushes and the commuter (?) bar, and it stops.

Anyone know if this can be fixed? I've searched the Internet until my eyes blurred and got nothing.

I took a video of it. If that will help I'll find a way to post it.

I don't see an exploded parts diagram online and the units are only sold as a complete unit, so the quick answer is no.

It is possible for a motor to develop an open circuit or a short, but it is just as likely that there is a problem in the gearing (clogged from food particles or syrups?). My guess is that if you removed the motor completely and ran it with no load that it would run fine.

I will. Thanks.

Same thing with no load. Wondering if it's the circuit board. I guess after 30 years we should be satisfied that we got our monies worth.

OK, if it does it with no load, check the brushes to make sure they are in decent condition. Some of the carbon brushes are reversable. The power going to the motor can also be checked with a multimeter. Does the motor stall out and hum, or just stop with no noise? Are there any burned components on the circuit board - rectifiers, capacitors? Do all the traces look clean and intact? I'm just trying to think of the possibilities with a chance of a fix.

[Tek_Freek]

No hum. Couldn't see any burned components and the traces are clean. I could reverse the brushes. Me and a multimeter is asking for trouble, lol. Brushes it is.

Appreciate it.
