How to Reset a Garbage Disposal

Learning how to reset garbage disposal units is one of the most useful five-minute homeowner skills you can pick up, because a tripped reset is one of the most common reasons a disposal goes silent. Almost every garbage disposal has a small red reset button on the bottom of the unit. When the motor overheats, jams, or draws too much current, an internal overload switch trips and cuts power to protect the motor. Pressing that red button restores power, and in many cases that is all it takes to bring a "dead" disposal back to life. This guide shows you exactly where the button is, what to do before you press it, and what to try when a reset alone does not solve the problem.

Where the Reset Button Is

The reset button on a garbage disposal is almost always on the bottom of the unit, facing the floor of the cabinet. It is usually a small red or black button, about the size of a pencil eraser, set into the center of the bottom housing. On many models it sits right next to the hex socket used to manually turn the flywheel. You will need to crouch or lie on your back under the sink with a flashlight to see it clearly, especially in a crowded cabinet.

On some models, particularly older or budget units, the button may be black rather than red, or it may be recessed slightly into the housing. If you cannot find it, check the brand and model label on the side of the unit and look up the manual online, but in practice, the bottom-center position holds for nearly all major brands, including InSinkErator, Waste King, and Moen. Do not confuse the reset button with the mounting screws or the drain connections on the side of the unit.

When the overload trips, the button usually pops out slightly. When you press it back in, you should feel a distinct click as it resets. If the button is already pushed in and does not move, the overload has not tripped, and your problem lies elsewhere, such as a tripped breaker, a tripped GFCI outlet, or a failed switch.

Before You Reset: Clear the Jam First

Pressing the reset button without clearing the cause of the trip is the most common mistake homeowners make. The overload tripped for a reason, usually a jam, and if the flywheel is still stuck, the motor will overheat again the moment you restore power, and the button will trip again. Worse, repeatedly resetting a jammed motor can burn it out.

Before you press the button, switch the disposal off at the wall switch. Then look inside the drain opening with a flashlight and remove any visible objects with tongs or pliers, never your fingers. Next, insert a 1/4-inch hex key into the socket on the bottom of the unit and work it back and forth until the flywheel turns freely in both directions. This rocking motion breaks the jam and clears packed food from the grinding chamber.

Only after the flywheel moves freely should you press the reset button. This order matters: clear first, reset second, test third. If you skip the clearing step and the disposal hums and trips again, switch it off immediately, clear the flywheel again, and then reset once more. If it trips a second time after a confirmed free flywheel, stop resetting and move to the troubleshooting steps later in this guide.

How to Reset a Garbage Disposal Step by Step

Here is the complete reset process, start to finish. Step one: switch the disposal off at the wall switch. If the switch is part of a combined outlet or you are unsure which switch controls the unit, switch off the disposal's breaker at your electrical panel for extra safety.

Step two: check for a jam. Look inside the drain with a flashlight, remove visible debris with tongs, and work the flywheel with a 1/4-inch hex key until it turns freely in both directions. Step three: locate the red reset button on the bottom of the unit and press it firmly until it clicks. It should stay pushed in. If it pops right back out, the motor may still be hot, so wait 10 to 15 minutes for it to cool and try again.

Step four: restore power. Flip the wall switch back on, or restore the breaker if you switched it off. Step five: run cold water into the sink, then flip the disposal switch on. Let it run with cold water for 20 to 30 seconds. If it spins up smoothly and grinds normally, the reset worked. Run a tray of ice cubes through it to scour the chamber and confirm it handles a load.

Step six: if the disposal runs but sounds rough or slow, switch it off, work the hex key again, and repeat the reset. Some stubborn jams need two rounds of clearing before the unit runs cleanly. If it runs smoothly after the second attempt, you are done, and the prevention tips at the end of this guide will help you avoid a repeat.

Resetting the Breaker and GFCI Outlet

Sometimes the problem is not the disposal's own reset button but the power feeding it. If pressing the red button does nothing and the disposal is completely silent, check your breaker panel. Find the breaker labeled for the disposal or kitchen, and if it is tripped, it will sit in a middle position between on and off. Switch it fully off, then fully on, to reset it.

Next, check for a GFCI outlet under the sink. Many kitchens have the disposal plugged into a GFCI-protected outlet, and a tripped GFCI cuts power to the disposal. The GFCI outlet has its own test and reset buttons on its face. Press the reset button on the outlet until it clicks. If the GFCI trips again immediately, there may be a ground fault in the disposal or its wiring, and you should stop and call an electrician or plumber.

Also check the wall switch itself. Switches wear out, and a failed switch can leave the disposal silent even though the reset button, breaker, and GFCI are all fine. If you hear no sound at all, the reset button is pushed in, and the breaker and GFCI are good, a failed switch or loose wiring is a likely cause. Switch replacement is a job for someone comfortable with electrical work, and it typically costs $175 to $350 professionally.

Why Your Disposal Needed a Reset

Understanding why the overload tripped helps you prevent it from happening again. The most common cause is a jam: a foreign object, a bone, or packed fibrous food stops the flywheel, the motor draws excess current trying to spin, and the overload trips to protect the motor from burning out. This is the overload doing its job, and it is a sign that something needed clearing, not that the disposal is broken.

Overloading is another common cause. Feeding too much food at once, especially starchy foods such as pasta and rice that swell, or fibrous foods such as celery and onion skins, can stall the flywheel even without a foreign object. Running the disposal without enough water has the same effect, because food packs in the chamber instead of flushing through. Always run cold water before, during, and after grinding, and feed scraps gradually.

Age and wear can also cause trips. As a disposal gets older, bearings wear, the motor works harder, and the overload becomes more sensitive. A unit that trips once a year is normal. A unit that trips every week is telling you something: either your usage needs to change, or the motor is wearing out and replacement is approaching.

When a Reset Does Not Fix It

If you have cleared the flywheel, pressed the reset button, confirmed the breaker and GFCI, and the disposal still does not work, work through these possibilities. If the disposal hums but does not spin, the flywheel may still be partially jammed, or the motor's start capacitor may have failed. Work the hex key again thoroughly, and if the flywheel is truly free but the unit only hums, a capacitor or motor problem is likely.

If the disposal is completely silent, the problem is electrical: a failed switch, loose wiring, a failed overload switch, or a burned-out motor. You can check the breaker, the GFCI, and the reset button, but opening the wiring compartment or testing the motor requires electrical knowledge and should be left to a professional. If the disposal trips the breaker every time it runs, stop using it and call an electrician, because a repeated breaker trip can indicate a short circuit.

If water leaks from the bottom of the unit, the internal seals have failed and the motor may be water-damaged. No reset will fix that, and the unit needs replacement. Similarly, if the disposal smells like burning, smokes, or makes grinding metal-on-metal noises after a reset, switch it off and do not use it again until a plumber has inspected it.

Reset Button Problems and Replacement

Reset buttons themselves can fail. A button that will not stay pushed in, even after the motor has cooled and the flywheel moves freely, usually means the overload switch is worn out or the motor is still drawing excess current. A button that feels loose, mushy, or does not click may have a broken internal spring. In both cases, the overload assembly needs attention.

On some higher-end models, the overload switch is a replaceable part, and a plumber can swap it for $150 to $300 including labor. On many budget models, the overload is built into the motor assembly and is not sold separately, which means the whole disposal must be replaced. Your plumber can tell you which case applies to your model by checking the brand and part availability.

Do not bypass, tape down, or wedge the reset button to keep the disposal running. The overload exists to prevent the motor from overheating and potentially starting a fire. Bypassing it is dangerous and voids the warranty. If the button will not stay in, treat that as a symptom, not an annoyance, and get the unit diagnosed.

Keeping Your Disposal Running Reliably

A few habits will keep your disposal out of the reset cycle. Always run cold water before, during, and for 20 to 30 seconds after grinding. Feed food gradually, and avoid the worst offenders: large bones, fruit pits, coffee grounds in bulk, pasta, rice, potato peels, grease, and fibrous vegetables. Never grind non-food items, and keep silverware away from the drain opening.

Run the disposal regularly, even when you have little to grind. A weekly run with ice cubes and water keeps the flywheel free and the seals moist, which prevents the seizure that causes so many resets after a vacation or a quiet period. Every few weeks, grind ice cubes and a citrus peel to clean the chamber and control odors. Never use chemical drain cleaners in a disposal, since they damage seals and create a hazard for anyone who later services the unit.

Finally, know when to stop resetting and start replacing. If your disposal trips more than once a month, is over 10 years old, or needs a repair that costs more than half a new unit, replacement is the smarter investment.
