G'day,

Split your problem then.

It's on the same breaker as the dish=ADwasher, which
still works.

Check/confirm 110-120 volts AC comming into the unit with a volt meter
and power there =3D a problem inside the disposal itself and then you can
weight the pros and cons....take apart the old unit for possible repair
( switch, burnt wires, cooked motor ) or replace the unit with a new
disposal.
