When you turn the mixer on and turn the dial for the speed, once you get to about 4 the head will move slightly and then you have to turn it up to about 10 before it moves again. You can turn the dial back and forth, the head will move, but it moves intermittently. It will not fully rotate at any speed.
I would take a swag at it and guess that the speed control has a variable capacitor consisting of a circular plate and wiper. The plate is a series of contact points that switch the speed control into the circuit. You are missing some of the contact points in the middle of the switching cycle or the wiper is not making contact at that part. You would have to replace the speed control part, but finding the part would not be easy and repairing it was not anticipated due to obsolete thinking on the design of the product.

For whatever reason, Sunbeam must have decided to cut on costs and used a plastic gear to transfer power to the beater. I had my Sunbeam for two years and the plastic gear decided to break. End of mixer. You cannot find a replacement part anywhere. It is the last sunbeam I will buy.
I would recommend that you first check the Hall effect sensor which determines the speed. I had this exact problem (but mine occurred with a 600 professional model) and I actually went out and bought another Hall sensor for about $13. I replaced the original sensor and made sure that the connection between the sensor and control board was nice and snug. My blender worked as good as new! But I was curious to know if my original sensor was defective so I put it back in mixer and again made sure all of the connections were tight. Guess what? My original sensor also made my mixer work! There was nothing wrong with my original Hall effect sensor except the connection between the control board and sensor was not adequate--unfortunately I didn't check the connections before I decided to buy another one. My guess is that the connection between the control board and the sensor probably loosens or comes undone over time from use and vibrations.
1. Download the mixer parts and diagrams from the Kitchenaid website to see what the Hall effect sensor looks like. 2. You'll need a phillips head screwdriver to open up the mixer. 3. Make sure that the connection between the control board and sensor is absolutely tight and snug. 4. Also, make sure that the orientation of the sensor connection between the control board and sensor is correct. it's hard to know which way the sensor should be connected because the control board has three prongs and the sensor can attach facing up or facing down. If, after you've made the connections, the mixer still doesn't work. Disconnect the sensor and reconnect it with the prongs facing the opposite direction and try it. I actually found the right orientation through trial and error. By going through this trial and error, I also had my Eureka moment when I realized that the original sensor probably would also work it were reconnected with correct orientation. 5. This whole process probably takes less than 10-15 minutes to perform.
SOURCE: Stand jumps
The height of the beater is easy to adjust on the tilt-head model. Tilt the head back, and look into the pivot from the front of the mixer. You should see a screw on the hinge. With a flat blade screwdriver, rotate this screw half a turn counter-clockwise to raise the beater height. Lower the head and check that the beater does not touch the bowl. Repeat until the adjustment is satisfactory. To lower the beater closer to the bowl, turn the screw clockwise instead.

I would recommend that you first check the Hall Effect sensor
which determines the mixer’s speed. I had this exact problem and I
actually went out and bought another Hall sensor for about $13. I
replaced the original sensor and made sure that the connection between the
sensor and control board was nice and snug. My mixer worked as good as new! But

My original sensor also made my mixer work! There was nothing wrong
with the original Hall Effect sensor except that the connection between the control
board and sensor was not tight--unfortunately I didn't check the connection
before I decided to buy another sensor. My guess is that the connection between
the control board and the sensor probably loosens or comes undone over time
from use and vibrations. To fix your problem:
1. Download the mixer
parts and diagrams from the Kitchenaid website to see
what the Hall Effect sensor looks like. BTW the part number is 9703312.
2. You'll need a phillips head screwdriver to open up the
mixer gear case cover.
3. Make sure that the connection between the control board
and sensor is absolutely tight and snug.
4. Also, make sure that the orientation of the sensor is
correct. It's difficult to tell which
way the sensor should be connected because the control board has three prongs
and the sensor can attach facing up or down. After you've made the connection,
run the mixer. If it still doesn't work, disconnect the sensor, reconnect it
with the prongs facing the opposite direction and try it again. I
actually found the right sensor orientation through a little trial and error.
But by going through this trial and error, I also had my Eureka moment when I realized that the
original sensor probably would also work if it were reconnected with correct
orientation.
5. This whole process probably takes about 10-15 minutes
to perform.
6. Finally, use your common sense
and make sure to unplug the mixer before checking, connecting or disconnecting
anything.
SOURCE: Turntable does not turn. Motor runs. Beaters work.
I have the same one, and the turn table has never turned on it's own. from looking at the bottom of the stand, i think the mixers are supposed to turn the bowl, so i just give it a little turn, and the mixers kinda take care of the rest. BTW, i got 2 sets of beaters with mine and i dont know what the second set is for, do you? contact me at [email protected]
