Betsy, I have an Insinkerator disposal of unknown age (it was in the house when I bought it). Twice it has locked up as you describe with the motor humming and not turning. Each time I was successful to turn the rotor by hand inside the sink drain to loosen it up. There was no debris in there. My assumption is that my unit is very old and the seals are damaged, allowing crud or corrosion to bind the motor shaft. I intend to replace the unit when it does finally quit.
You mentioned that your disposal is a Kenmore. I subscribe to Sears e-mail advertisements. Sales on appliances have been occurring a few times each month. Some include free shipping. It is worth checking out if you want to get another Kenmore. I have also read that bigger is better (power-wise) if your previous unit has had trouble digesting stuff. I cannot help you about a wall hung toilet other than it must need a very strong wall to mount to and a thick wall for the drain pipe to turn down through. - Gil Laster, Charlotte, NC [Non-text portions of this message have been removed]
