Garbage Disposal Not Working
A garbage disposal that does nothing at all has usually tripped its own reset button or the breaker. If it hums instead, it has power but the grinding plate is jammed.
Before you start: Never put your hand into a disposal. Switch it off at the breaker before reaching into the chamber at all.

| Tripped reset button | Most common | DIY |
| Tripped breaker | Common | DIY |

1. Tripped reset buttonYou can check this
How to check: Look underneath the unit for a small red button. If it has popped out, the motor overloaded and shut itself down.
The fix: Let the motor cool for ten minutes, then press the button firmly back in.
2. Tripped breakerYou can check this
How to check: Check the kitchen circuit at the panel.
The fix: Reset it. Repeated tripping means an electrical fault — stop and get it looked at.
3. Jammed grinding plateYou can check this
How to check: A hum with no rotation. See the humming guidance below.
The fix: Free the jam with the hex wrench before it overheats the motor.
4. Failed wall switchTechnician job
How to check: No sound at all with the reset pushed in and the breaker on.
The fix: Switch replacement — an electrician's job.
5. Burned-out motorTechnician job
How to check: No response after resetting, with confirmed power at the unit.
The fix: Replace the disposal. Motors are not economically repairable.
When to call a technician
If the reset and breaker are both fine and the unit is silent, the switch or motor has failed.
