Home warranty guy: Did you hit the red reset button?
Me: Huh? What reset button?
Home warranty guy: There's a red reset button on the bottom. Try pushing it.
Me: Oh, ok. I never knew a garbage disposal had a reset button. Hang on.
I hit the red reset button and now nothing at all happens. No hum. Nada.
Me: Crap. (then I get back on the phone)
Me: Nope. Didn't work. Now there's not even a hum.
Home warranty guy: Ok, the plumber will call you within 24 hours and come fix it. That'll be $50.
Me: Ok (thinking "oh crap, FIFTY bucks (!), but better than $100 for a new one plus another $100 for somebody to install it)
I decided to Google "garbage disposal reset button" and found this site: http://www.expertvillage.com/video/52_garbage-disposal-repair.htm
I fixed the problem with a simple twist of an allen wrench. My, my...what shall I accomplish next? Maybe I'll tackle installing a new ceiling fan. ;)
