Have an in the sink garbage disposal.
Will not turn when power is applied, but does make a "buzzing noise", so the
circuit breaker apparently
is not the problem.
Also, the impeller turns easily and smoothly when turned by hand.
Also, putting an Allen wrench in the bottom hole also turns very easily.
Usually, the impeller gets jammed, and won't turn until it's cleared.
But that does not seem to be the case here.
Any thoughts ?
