Just moved into a home with an Insinkerator Pro 17. After using it for about a month, it won't work... it hums when I try to engage it, I've tried the reset button, and it doesn't help. I've tried spinning it with a wrench but it won't budge. There is possibly a lemon pit caught... is there an easy way to take apart?

With a flashlight try to see what is jamming disposal. Take a stick, like a broom handle about 2 foot long, stick down disposal and try to turn counter clock wise.

I can't see anything that is jamming it and I can't turn it manually... but it hums when I turn it on
