Garbage Disposal Not Working? How to Fix a Jam Safely

Here is the safe, step by step way to handle a disposal that has stopped working, and when it is time to call.

Humming but not turning: a jam

A disposal that hums without spinning has something jamming the flywheel, often a bone, a fruit pit, or fibrous scraps. The motor is running but cannot turn, and if you leave it humming it will overheat. Switch it off at the wall first.

Most disposals come with a small hex, or Allen, wrench that fits a socket in the center of the underside. Insert it and work it back and forth to free the flywheel by hand. Then remove whatever caused the jam from the top, using tongs, never your fingers, and press the reset button underneath before switching it back on.

Completely dead: check power first

Press the reset button on the bottom of the unit; it pops out when tripped
Check the breaker in your panel and reset it if it has tripped
Make sure it is not simply switched off at the wall or a switched outlet
If it stays dead after all that, the motor or wiring has likely failed

A disposal that is truly dead with power confirmed, no hum, no response, usually has a burned out motor, and at that point replacement is normally cheaper than repair.

The one safety rule

Never put your hand into a garbage disposal, even when it is switched off and even when you are sure it is safe. Use tongs or pliers to remove anything from inside, and turn the flywheel with the wrench from underneath. Disposals are the source of serious hand injuries precisely when people are certain the power is off. If you cannot clear it safely from outside, that is the point to call rather than reach in.

Repair or replace the disposal

Disposal problems and the usual call
Symptom	Usual call
Hums, jammed	Free the flywheel, reset
Dead, reset or breaker tripped	Reset; often an easy fix
Dead, power confirmed	Motor failed; usually replace
Leaking from the body	Replace the unit
Slow drain below it	Clog past the disposal; clear the line

A jam or a tripped reset is worth fixing on the spot. A burned out motor or a leaking body is usually a case for replacement.

A note for homes on septic

Most of Largo is on city sewer, but on the unincorporated fringe some homes run on septic. If yours does, go easy on the disposal, since it sends more solids to the tank, which then needs pumping more often. Fibrous and starchy scraps are best kept out. And if a sink drains slowly even when the disposal runs clean, the real problem is usually a clog further down the line, not the disposal itself, common in the older homes around Seminole.

How to keep a disposal healthy in Florida

A few habits keep a disposal working and cut down on jams and clogs. Run cold water before, during and for several seconds after grinding, so the debris is carried down the line rather than settling in a cooled, scaled pipe. Feed waste in gradually instead of packing it in all at once. Keep out the things that reliably cause trouble: fibrous scraps like celery and corn husks that wrap the blades, starchy foods like potato peels and pasta that turn to paste, bones and fruit pits that jam the flywheel, and grease, which coats and clogs the line downstream.

To keep it smelling fresh, grinding a few ice cubes helps knock residue off the grinding components, and a little citrus peel freshens it. If a sink still drains slowly even when the disposal spins freely, the problem is a clog further down, not the disposal, and that is ordinary drain cleaning territory, common in the older cast iron kitchen lines around Seminole. And if the home is on septic, go especially easy, since a disposal sends more solids to the tank and shortens the time between pump outs.

Common questions

Why does my garbage disposal hum but not spin?

It is jammed. The motor is running but something, often a bone, pit or fibrous scrap, is stopping the flywheel from turning. Switch it off, use the hex wrench in the bottom to work the flywheel free, remove the obstruction with tongs, and press the reset button. Do not leave it humming, as that overheats the motor.

Where is the reset button on a garbage disposal?

It is on the bottom of the unit, usually a small red or black button in the center or off to one side. When the disposal overloads it trips and pops out; pressing it back in resets the unit. If it trips again right away, something is still jamming it or the motor is struggling, so investigate before repeatedly resetting.

Is it safe to reach into a garbage disposal?

No, never put your hand into a disposal, even switched off. Use tongs or pliers to remove anything inside, and turn the flywheel with the wrench from underneath. Disposals cause serious hand injuries exactly when people believe the power is off. If you cannot clear it safely from outside, call a plumber instead of reaching in.

Should I repair or replace a broken disposal?

A jam or a tripped reset is a quick fix worth doing. A disposal with a burned out motor or a leaking body is usually cheaper to replace than repair, especially if it is older. A plumber can tell you which situation you are in and, if replacing, fit a new unit quickly.

What should I never put down a garbage disposal?

Fibrous scraps like celery and corn husks that wrap the blades, starchy foods like potato peels and pasta that turn to paste, bones and fruit pits that jam the flywheel, and grease, which coats and clogs the line downstream. Running plenty of cold water and feeding waste in gradually, rather than all at once, prevents most jams and clogs.

How do I keep my garbage disposal from smelling?

Grinding a few ice cubes helps knock residue off the grinding components, and a little citrus peel freshens it up. Running cold water for a few seconds after each use clears out debris that would otherwise sit and smell. If an odor persists despite this, or the sink drains slowly, the issue may be buildup further down the line rather than the disposal itself.
