Garbage Disposal Not Working? What to Check First

Editorially reviewedBy the Home Services Resource Center Editorial TeamLast reviewed:

This guide is written to help homeowners understand common plumbing repair, installation, water heater, drain, and emergency considerations. It is educational and is not a substitute for an on-site evaluation by a licensed plumber. HSRC does not perform work directly, set contractor pricing, or guarantee availability — services and response times vary by location and provider.

Quick Answer
If the disposal is silent, try the reset button on the bottom. If it hums but doesn't turn, the impeller is likely jammed — use a hex key in the bottom port to free it. Never put hands inside a disposal.
Key Takeaways
  • Reset button first
  • Hex-key the bottom port if jammed
  • Never put hands inside
  • If the motor fails, replacement is usually next

Step-by-step troubleshooting

Turn off the switch, press the reset, then test. If humming, disconnect power and use the hex key. If silent after reset, check the breaker.
