I inherited an original vintage Cuisinart Food Processor from the 70's, after using it a few times it stopped working. I realized that the problem was the safety switch that connects when the bowl and lid are on the unit. This keeps you from turning it on when your hands are in harms way. Make sure you are putting the bowl and the top piece on and rotate them to the right! If you don't do this then the switch is not activated and it will not work!

You can see the spring loaded mechanism in the bowl handle that pushes the switch through a hole in the base, this allows you to turn it on. My switch had dropped down inside the unit so that the mechanism could not push it enough to activate it. This keeps the unit from working.

Remove the bowl and flip the base upside down putting the center shaft through the tube in the bowl.
-
Now peel off the rubber feet to reveal the screw holes holding the top and bottom covers together. Unscrew those 4 screws under the feet with a #2 Phillips screwdriver. One of my screws was just spinning because the part it attached to in the top cover had broken off.

Remove the bottom cover & look inside of the top cover for the safety microswitch. If your switch is like mine it came loose because the screw attachment locations on the top cover broke loose and came off. With no way to get a new top cover the only way to fix it right is to reattach the switch to its original location using small machine screws.

I got 2 - 1 inch long #6 flathead stainless steel screws with nylon lock nuts to fasten the safety switch back to the top cover in the right place. I also got two 1/4' nylon spacers to go between the switch housing and the top cover to replace the pieces that broke off.

-
Next I used a drill bit that was as close to the size of the screws and drilled through the top cover where the previous screws used to attach. Be careful that you don't drill into the bowl when you are doing this.
-
Then I used a bigger drill bit on the top of the top cover to countersink the screw heads into the top of the top cover since there is a close clearance when putting the bowl on. Be gentle with the drilling since the old plastic is really brittle.
-
If I had it to do over again I might try to rotate the safety switch so that the one screw would both be farther away from where the bowl goes. (The cracks in the top cover were there before I started working on it!)

-
Once you have drilled and drilled to countersink the screw heads, it's time to put it together. Run both screws through the top and then put the 1/4 inch nylon spacers on the screws.
-
Now put the rubber seal in the top cover. Next the nylon plunger goes in the rubber seal with the big side down. Last the spring goes around the nylon plunger. Small side down.
-
-
-
Next put the switch housing over the seal plunger spring assembly and put the lock nuts on the screws and gently tighten. Make sure you don't crack the top case by tightening too tight!

I would not screw the bottom cover down until you test it to make sure it works. Now flip the unit over and place it on the black bottom cover. Make sure you put the bowl and the top pice on and rotated to the right! If you don't do this then it will not work. Then test to see if it's working.

The last step is to glue the rubber feet back on the bottom with some rubber cement.
