When a garbage disposal suddenly goes dead, no hum, no grind, nothing, most people assume it is broken and start pricing replacements or plumbers. In reality, the fix is almost always a single button hidden where you would never think to look. The garbage disposal reset button location is on the underside of the unit, tucked up beneath your sink where it is easy to miss entirely. This small red or black button pops out when the disposal’s built-in overload protection trips, cutting power to save the motor. Pressing it back in restores power, and you are back in business, often in under two minutes and at zero cost.

Where the Reset Button Is Located
The reset button lives on the bottom of the disposal unit, dead center or slightly off-center on the lowest point of the motor housing. You will not see it from a standing position; you have to open the cabinet under your sink, get down low, and look up at the underside of the disposal.
It is a small button, usually red, though some brands like older Waste King models use black, that protrudes about a quarter inch when tripped. Reach up and feel around the very bottom of the unit if the cabinet is dark. A flashlight helps enormously here. Once you locate it, you will recognize it instantly, and you will know exactly where to go the next time the disposal quits.
Why the Button Trips in the First Place
The reset button is part of an overload protection system built into the motor. When the disposal draws too much current, from a jam, overheating, or a stuck flywheel, the internal breaker trips and pops the button out, cutting power before the motor burns up. It is a safety feature doing its job, not a malfunction.
Common triggers include jamming the unit with too much food at once, fibrous scraps like celery or corn husks wrapping the blades, running it too long without enough water, or a foreign object like a bottle cap or utensil falling in. The disposal shuts itself off to protect the motor. Understanding this tells you that a tripped reset button is usually a symptom of something you fed it, so clearing the underlying jam matters too.
How to Reset the Disposal Step by Step
Resetting is simple, but do it safely and in the right order so you do not just trip it again immediately or, worse, injure yourself.
- Turn off the disposal switch on the wall so the unit cannot start unexpectedly
- Look under the sink and locate the reset button on the bottom of the unit
- If the button is popped out, press it firmly straight in until it clicks and stays
- Wait 5 to 10 minutes if the unit felt hot, letting the motor cool before restarting
- Run cold water, flip the switch, and listen for normal operation
If the button will not stay pressed in, the motor is still too hot, wait longer and try again. Never put your hand into the disposal chamber, even with the power off.
What to Do if It Hums but Won’t Spin
Sometimes pressing reset restores power but the disposal only hums without grinding. That hum means the motor is getting power but the flywheel is jammed and cannot turn. Do not keep flipping the switch, because running a jammed motor will trip the reset again or burn it out.
Turn off the power at the wall switch. Most disposals include a hex-shaped hole in the very center of the bottom, right near the reset button, that accepts a 1/4-inch Allen wrench. Insert the wrench and crank it back and forth to manually free the stuck flywheel. Many units even ship with the correct wrench clipped nearby. Once the flywheel turns freely, remove the wrench, press the reset button if it popped, restore power, and test with cold water running.
Clearing a Jam Before You Reset
If something is physically stuck in the chamber, resetting alone will not help until you remove it. With the power off at the wall and, for extra safety, unplugged or the breaker off, shine a flashlight into the disposal from above.
Use tongs or pliers, never your fingers, to fish out any visible foreign object like a bone, a fruit pit, a bottle cap, or a piece of silverware. Turn the flywheel with the Allen wrench from below to loosen any wedged debris. Once the chamber is clear and the flywheel spins freely, restore power, press the reset button, run cold water, and switch it on. Removing the culprit prevents the disposal from immediately tripping again the moment it tries to spin.
When the Reset Button Does Nothing
If you press the reset button and the disposal still shows no life, no hum at all, the problem is upstream of the disposal itself. Check the wall switch, then the circuit breaker in your electrical panel, since a tripped household breaker cuts power entirely. Some disposals plug into an outlet under the sink; confirm it is plugged in and the outlet has power.
If the breaker is fine, the outlet is live, and pressing reset still yields nothing but silence, the motor or internal wiring has likely failed. A disposal that hums but the flywheel is free, or one that is completely dead after confirming power, has usually reached the end of its life. Most units last 8 to 15 years, so replacement rather than repair is the sensible next step at that point.
Reset Button Locations by Brand
While the reset button is on the bottom of virtually every disposal, the exact spot and color vary slightly by manufacturer, and knowing your brand speeds up the hunt. The button is always on the lowest point of the motor housing, but its placement and appearance differ.
- InSinkErator: a red button, usually dead center on the bottom of the unit
- Waste King: often a black or red button on the underside, near the center
- Moen: a red reset button on the bottom, with a matching hex hole for jams
- Kenmore and GE: a red button centered on the base plate
Whatever the brand, the routine is identical: cut the power at the wall, feel or look for the protruding button on the bottom, and press it firmly back in until it clicks and stays. If your unit came with a manual or a jam wrench clipped to the underside, that wrench fits the hex hole right beside the reset button for freeing a stuck flywheel.
How the Overload Protection Works
It helps to understand what is actually happening inside when the button trips, because it turns a mysterious failure into a predictable, manageable event. Every disposal motor has a built-in thermal overload protector, a small bimetallic switch that senses excess current or heat. When the motor draws too much power, from a jam, a stuck flywheel, or prolonged running, that switch opens, cutting power and popping the reset button out.
This is deliberate engineering, not a defect. The overload protector sacrifices a moment of inconvenience to save the motor from burning out, which would mean a full replacement. Once the underlying cause is cleared and the motor has cooled, pressing the button re-closes the switch and restores power. That cooling period matters: if the motor is still hot, the protector will refuse to stay reset until the temperature drops, which is why waiting five to ten minutes before pressing the button often makes the difference between a successful reset and a button that keeps popping back out.
Preventing Future Trips
Now that you know the garbage disposal reset button location and how to use it, a few habits will keep you from needing it. Always run cold water before, during, and for several seconds after grinding, and feed scraps in gradually rather than cramming the chamber full.
Avoid the notorious jam-makers: fibrous vegetables like celery and corn husks, starchy items like potato peels, grease, and hard bones. Keep utensils and bottle caps away from the drain. Grind a few ice cubes periodically to knock buildup off the blades. Treat the disposal well and that little red button on the bottom will rarely trip, but when it does, you now know exactly where it is and how to bring your disposal back to life in a couple of minutes.
