Garbage Disposal Hums but Won’t Spin — 5 Quick Fixes

That humming sound means the motor has power, but the impeller may be jammed or the overload tripped. Work through these safe steps in order.

The fixes

1. Reset the overload: Turn power off. Press the red reset button under the unit.
2. Free the jam: Insert a ¼" hex key into the bottom socket and work it back and forth until it spins freely.
3. Clear the opening: Power off; wear cut-resistant gloves and remove debris at the splash guard.
4. Replace torn splash guard: A worn guard traps scraps and smells—swap it if the flaps are ripped.
5. Flush & deodorize: Cold water on, disposal on, then dose a bio-enzyme cleaner per label.
