Re: Capacitor

Further to my post the distance can be varied. By adjusting the screws in and out in line with checking the operation of the speed control will correct any speed issues. As the motor has to be outside of the machine to do this it is advisable to strap it down and take precautions against electric shock. It seems there is a contact which opens and closes which triggers the triac. Old fashioned mechanical means.

Re: Capacitor

I have also repaired a chef A901 with motor speed issues. I had already replaced the caps and resistors. I found that there are two screws on the edge of the motor. If you unscrew these slightly and then adjust the pressure on the arm slowly till it regulates the speed. The speed now works correctly from slow to fast. There is a contact which has some feedback to the trigger circuit which maintains the motor speed. the gap is about 1cm/ or 1/2 in but could vary slightly between models. Both gaps have to be the same. Anyone wish to add their twopennuth?
