Ok, I have replaced the Speed control and it still made no diffrence. My mixer will still go from off to a high speed then shut off.(not the highest speed but fast). If I go from off to the highest speed setting, the mixer will hit the max speed revolutions and then shut off. Could it be the Hall sensor? Help!
Answer Hi Eric. The hall effect sensor is part # 9703312. Look carefully at the motor commutator where the motor brushes hold against the commutator. Slowly rotate the armature. Look at the gaps in between the commutator bars. The Mica-insulator gaps should be evenly spaced between the bars. Normally wearing together as the brush wears also.If you see a area where the bar gaps have arched and burnt open, then the commutator is shorted. Motor Part # 9706251. Always one way to tell is if the motor continuously sparks while running. Thank You.
My machine was kicking into higher speeds randomly and then stopping. I was told to replace the switch which I did and it did not change anything. Could it be this sensor that is causing the machine to operate incorrectly?
Answer Hi Todd. You need to change the speed control part # 9706650. Make sure all connections are tight. Static ground yourself to bare metal a few times so you do not touch any internal new board parts w/static. Touch only the corners of the board. Thank You.
Can a faulty sensor cause a complete shut down of the mach? I have power 120v to the speed control but nothing happens. The motor ohms ok. Not shorted or open and turns freely by hand.
Answer Hello Doug. Here is what the manufacture recommends for a mixer that does not run. The hall sensor can prevent the machine from running, but you need to test the speed control and see if it is sending power to the motor. Power should come in and go out. Hope this helps.
