I have a chrome mixmaster stand mixer, unmarked for model number, voltage or current. It looks very similar to the model 2360, but has an adjustment lever for bowl position. But the big difference from other models I can find pictures of is the beater release eject mechanism. The top handle rotates about 30 degrees to eject the beaters. Also, the beaters for this model have two slots forming a plus or cross at the top end of the shaft. The slots engage a cross-wire in the beater shaft sockets in the bottom of the motor housing.
My mixer made an unusual amount of sparks visible through the ventilation slots near the front of the motor, and then stopped. It makes no sound when turned on.
I've worked on and disassembled lots of motors and several small appliances, but can't find a way to disassemble the mixer housing. There are two screws exposed by rotating the top handle to the beater eject position, and they loosen the two halves of the housing at the front end, but the halves won't separate.
I'm afraid to pry too hard on the speed control knob, which seems to be in two parts - a chrome part in the center, and a brown plastic outer skirt with the 12 speeds marked on it. There is also a circular Sunbeam logo disk attached to the front of the motor housing, but it doesn't pry off easily either. On other discussion boards I read about prying the knob and disk off, but they were discussing other, probably older, models.
This machine is new enough to have a plastic (non-metallic) brown turntable.
We just got this mixer from my mother and have used it for about 2 weeks. Now that we depend on it, it gave up and I need to fix it.

Any help would be greatly appreciated.

Thanks,

Doug

EDIT: The first thing you want to check/remove is the brushes

I had an A10, yep an old model.

The back knob came out this way:

1. The chrome button prys out. It's just a cover.
2. Under that button is a screw.
2a. MAKE SURE SCREW HEAD IS FACING DOWN AND LEVEL
3. remove screw
4. Gently lift speed dial and remove.

There is a small piece that you don't want to loose. It will fall out in your hand, if you turn it over into your hand.

This piece rides on a cam on the knob and changes the speeds. It can be adjusted.

The two buttons with a slot on either side of the mixer are the brush holders and they will eventually have to be removed.

Not exactly sure about your model.

After further research reading, I found where to look for the ID number on the motor. It's marked as 120 volts, 225 watts, and Service Number 1-8B.

I can't find any model number, or identify it by online manuals or pictures.

This machine has no buttons on the side. I've removed brush holder buttons on several other DC and universal motors, but this motor does not have externally accessible brushes. They are the first things I wanted to check. I've had worn-out brushes before, with the metal follower sparking against the commutator. Although I haven't had to do it, I know how to turn the commutator and even undercut the segments.



Thanks,
