Garbage Disposal Not Working: Reset, Repair or Remove It?
Garbage disposals are inexpensive compared with other kitchen appliances, and they are usually replaced rather than rebuilt. But a disposal that hums, stops or drains slowly is often just jammed or tripped — and fixing that takes five minutes.
Quick fixes to try first
It does nothing at all
Look for the red reset button on the bottom of the unit. Disposals have a thermal overload that trips if the motor overheats. Wait a few minutes, press the button firmly, and try again. Also check the breaker and, if the disposal plugs in under the sink, the outlet.
It hums but does not turn
The flywheel is jammed. Turn off the switch and the breaker. Insert a hex key (usually 1/4 inch) into the socket in the center of the bottom of the unit and work it back and forth to free the flywheel. Remove the obstruction from above with tongs — never your hand. Press the reset button and test.
It drains slowly
Run cold water and the disposal together for longer. If the sink still drains slowly, the blockage is likely in the trap or drain line below the disposal.
When repair is not worth it
- Leaks from the body of the unit: the internal seals have failed. Leaks from the sink flange or drain connections can be fixed, but a leaking housing means replacement.
- Repeated tripping with no jam suggests a worn motor.
- Grinding noises after the jam is cleared can mean damaged bearings or a broken grinding plate.
- Age: disposals typically last 8–12 years.
How to remove a garbage disposal
- Turn off the breaker and unplug the disposal, or disconnect its hard-wired connection at the unit.
- Disconnect the dishwasher drain hose from the disposal inlet.
- Loosen the slip nut on the discharge tube.
- Support the disposal from below, then turn the mounting ring counter-clockwise until the unit drops free. It is heavier than it looks.
- If you are not replacing it, remove the sink flange and install a standard sink strainer.
Old disposals are mostly steel and can go to a scrap yard or recycling center; many cities also accept them with household metal items.
Repair or replacement by a pro
If the disposal is hard-wired, if the drain connections are corroded, or if you simply want it done properly, a technician can diagnose and handle garbage disposal repair and replacement in a single visit.
