Step 1 · Disconnect Power (Safety First!)

The absolute most critical first step is to ensure there is no power going to the garbage disposal. Locate the power cord for the disposal under the sink and unplug it from the wall outlet. If the unit is hardwired and does not have a plug, you must go to your home's main electrical panel (breaker box) and turn off the circuit breaker that controls the garbage disposal. Verify the power is off by attempting to flip the disposal switch on the wall; there should be no sound or movement.
