KitchenAid A-9 Electric Burr Grinder Questions & Answers
KCG200WH1 model
If you mean a chrome with serrated edges then that is a screw type ring that screws on the toggle switch on the outside to hold the switch tight in place against the body of the grinder. Place the ring over the toggle and hold the switch in place and screw the little ring on until tight.
Reach/remove pin.
Patricia, I am not sure which model you have old or new. I have the old one built in the 30's. I had to replace the shear pin and the carbon brushes for the motor. I took the bottom off which has a ball bearing resting loosely in a cavity in the bottom plate. Don't lose it. Now the brushes I found at an ace hardware. Take the old ones to compare. I think there was a bracket holding the brushes and rotor in. Once the rotor was out you could get the brushes out. Putting the brushes in required figuring out how to keep the brushes retracted. I used a piece of paper and used it hold them back while sliding in the rotor. Once in pull the paper out.
Now the shear pin needs to be in to prevent damage to the grinder in case what you are grinding has something too hard to grind like a small rock, I think if you push up on the rotor when the bottom plate is off or pulling up on the shaft it might give enough clearance to put the shear pin in. It sits very close to the bottom of the shaft so it can be fun trying to line it up. I used needle nose pliers to hold the pin just right while pulling up on the shaft. I bought the shear pin off of ebay
Motor quit running
I recently found one and it wouldn't turn so I took off the top burr and it would turn on so I would start with a thorough cleaning of the burrs then check the setting of the burrs, if they are too close the they wont allow the motor to run. Next if the motor runs but the burrs don't turn it would be a sheared shear pin which is designed to shear in case a pebble got in the coffee before damage could occurThird worn motor brushes. My motor was intermittent and found the brushes down to nothing. Now I am looking for new ones
Can not turn the grind
Same thing happened to me. It turned out the cause was a build up of hardened coffee grounds. We took it apart (a bit tricky!) and cleaned it. Now works like new.
I can no longer turn
Same thing here. We ended up taking it apart. Took a bit of time and a few tools, but basically the oils from coffee 'gum up' the parts. I couldn't get it to turn to FINE, as dial was stuck. I had two handy guys that did it for me. A pair of pliers and a screwdriver were involved. There was some really hardened chunks of coffee that had caused it. Works like new now!
My A-9 Coffee grinder no longer grinds coffee.
This fixes almost all the "beans will not feed or beans will not grind"
problems caused by coffee bean dust packed in the burrs. Oily beans
cause this problem more fequently.
a. Pour all the beans out the top.
b. Open the settings up all the way and see what else can be poured
out. Use your shop vacuum to **** grounds out the spout and backward
out the bean bin.
c. Pour in some instant rice and start grinding. Reduce the grind to
a small setting like six and then open the settings all the way again.
(The grinder will not start at a low setting with the rice in it. If
you let it stop, open the settings to about 16 before trying to
restart.)
d. Pour out the rice and vacuum out the ground rice.
e. Adjust the grinder to your favorite setting and try a coffee grind.
Grind until most of the rice dust is expelled (any remaining trace of
rice dust will not affect the flavor of the coffee).
