Disposals fail in three ways: they jam, they lose power, or they leak. The first two are often fixable without parts. The third depends on where the water is coming from.
Never reach into a disposal. All of the safe fixes happen from underneath the sink with the power off.

Safe disposal troubleshooting
If it hums but still won't turn, or trips the breaker, the motor or wiring may be failing and it's time to call.
- Turn the switch off and, if it's plugged in, unplug it
- Use the hex key in the bottom center of the unit to work the plates back and forth
- Remove any object with tongs, never your hand
- Wait a few minutes, then press the red reset button on the bottom
- Restore power and run cold water before switching on
Repair or replace?
Most disposals last 8 to 15 years. A leak from the body of the unit, a motor that won't run after a reset, or repeated jams in an older unit usually mean replacement. Leaks at the sink flange or the dishwasher connection can often be repaired. When replacing, matching the horsepower to how you cook and choosing a unit with a stainless grinding chamber gives longer life.
