Sometimes it would work on one speed. Then it stopped all together.
Nieu, I'm not sure what kind of mixer you have nor am I should what the one speed is. In my case, I have KA 575 watt professional 6 model that would operate at only the highest speed regardless of setting. If your problem is similar to this, I would recommend that you first check the Hall Effect sensor
which determines the mixer’s speed. I 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
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 absolutely 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 the new sensor. My best guess is that the connection between
the control board and the sensor probably loosens and comes undone over time
from use and vibrations. Follow these steps:
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 for my model.
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 less than 10-15 minutes
to perform.
6. Use your common sense
and make sure to unplug the mixer before checking, connecting or disconnecting
anything.
