If your disposer is permanently connected to the electrical system using Romex, BX, conduit, or another permanent means, check the circuit breaker or fuse. To be certain, switch the breaker off then on, or replace the fuse. If the disposer still does not run, the problem may be in the disposer, or in the electrical system. Either case requires service.
An InSinkErator authorized service center can test the disposer. If the problem is in the disposer and the disposer is covered by warranty, InSinkErator will pay to have an authorized service center service the disposer in your home at no charge to you.
If the problem is in your electrical system, you will be responsible for the testing and repairs.
