Our home garbage disposal is a Kenmore model, recommended to us by our longtime trusted appliance repair guy. I think it's a 3/4 hp model; it's certainly a big one.
One thing this disposal does not do that previous Insinkerator models did well is dispose of chicken bones. The Insinkerators would, in 30 seconds or less, take several chicken drumsticks and flush them and the disposal would again run quietly.
By contrast, the Kenmore gets rid of MOST of the bone, but has problems with the cartilage, and the small chips of the bone just rattle around making noise and getting stuck under the grinders (or whatever the sharp twirly projections in the disposal are called, that grind the garbage). Yesterday, I pulled out of the disposal a large heaping handful of cartilage bits and pulverized and smooth-edged bits of bone, and the disposal is still making rattling noises.
Is this normal? Understand, the disposal doesn't balk at chicken bones going into it (we've never ever tried turkey bones) - it smoothly chops them up in seconds. What it's failing to do is chop up the small pieces and flush them out.
If this isn't normal, what are some simple fixes/adjustments I might make to correct this?
