Why is my garbage disposal not working?
Why Did My Garbage Disposal Stop Working?
When your garbage disposal stops working, the issue typically falls into one of these categories:
No power / won't turn on:
- ✔ Tripped circuit breaker or blown fuse
- ✔ Overload protector (red reset button on bottom of unit) has been triggered
- ✔ Faulty wall switch or switch wiring
- ✔ Motor failure (often accompanied by humming sound)
Runs but doesn't grind:
- ✔ Jammed impeller plate (blades can't rotate)
- ✔ Foreign object lodged between impeller and shredder ring
- ✔ Worn cutting components from age or improper use
Leaking:
- ✔ Loose connections at sink flange, discharge pipe, or dishwasher connection
- ✔ Cracked disposal body or internal seals
- ✔ Improperly installed components
Safety Warning: Never put your hand in the garbage disposal, even when turned off. Always disconnect power before attempting any inspection or repair.
Our plumbers can safely diagnose and repair most disposal issues, or recommend replacement if the unit has reached the end of its useful life (typically 8–15 years). We also provide guidance on proper disposal use to prevent future problems.
