My In-sinkerator was working, then it suddenly stopped. When I turn
it on now, I hear a "hum" -- as if it is in fact turned on, but no
grinding or anything. I've read some tips, put a plunger handle in
there with the power off. It doesn't "seem" like it is clogged,
although I know that may not be the case. The "hum" when I turn it on
almost makes me believe that it turns on, but maybe the motor is
dead? It is about 12 years old.

Any help is appreciated.

Thanks.
