How to Reset a Garbage Disposal in 5 Simple Steps

Your Garbage Disposal Stopped Working — Here's What to Do First

Knowing how to reset a garbage disposal safely can save you a stressful morning and an unnecessary service call. Before anything else, here's the quick answer:

How to reset a garbage disposal safely:

1. Turn off the wall switch and unplug the unit from under the sink.
2. Wait 5 to 15 minutes to let the motor cool down.
3. Locate the red reset button on the bottom of the disposal unit.
4. Press the button firmly until you feel or hear it click into place.
5. Restore power, run cold water, and test the disposal.

That's the core process. According to research across multiple plumbing sources, over 80% of garbage disposal issues can be resolved by homeowners without a professional — and a simple reset is often all it takes.

Here's the thing: your garbage disposal doesn't just "break." It has a built-in thermal overload switch that automatically shuts the unit off when it overheats or gets jammed. Think of it like a mini circuit breaker protecting the motor. When that switch trips, the disposal goes silent — and most homeowners assume the worst. In reality, it's usually a quick fix you can handle yourself in under ten minutes.

Why Your Garbage Disposal Trips and Needs a Reset

Before we dive into the physical steps of resetting your unit, it is helpful to understand why this happens in the first place. Your garbage disposal is a tough kitchen workhorse, but it has limits. When those limits are pushed, the built-in thermal protection system trips to prevent the motor from burning out entirely.

There are three primary reasons your unit's internal circuit breaker will trip:

1. Mechanical Jams: This is the culprit behind roughly 50% of all disposal failures. A jam occurs when something hard, fibrous, or metallic gets wedged between the rotating impeller plate (or flywheel) and the outer grind ring. Common offenders include fruit pits, small bones, silverware handles, or even a build-up of fibrous celery strings. When the plate cannot spin, the motor stalls, draws too much electrical current, and trips the thermal switch to save itself.
2. Motor Overload: Even without a hard jam, feeding too much waste into the disposal too quickly can overload the motor. The motor has to work extra hard to grind down a massive heap of food, causing it to quickly overheat.
3. Electrical Spikes or Long Run Times: Running the disposal continuously for several minutes without sufficient cold water can cause the motor to heat up naturally. If it crosses a safe temperature threshold, the thermal overload switch pops out, shutting down power instantly.

To help keep your kitchen running smoothly, understanding the basics of Caring for Your Garbage Disposal is essential. If your disposal stops working, you need to determine whether you are dealing with a simple electrical trip or a mechanical jam.

How to Reset a Garbage Disposal Safely in 5 Steps

If your disposal has gone completely silent or is humming without grinding, follow this simple, safe, 5-step process to get it back up and running. This method is designed to protect both you and your kitchen's electrical system. For a comprehensive overview of fixing common issues, refer to our Garbage Disposal Repair Guide 2026.

Step 1: Turn Off the Power (Completely!)

Never attempt to diagnose, touch, or reset a garbage disposal while there is a chance it could turn on. Turn the wall switch to the "OFF" position. For absolute safety, go under the sink and unplug the power cord from the wall outlet. If your disposal is hardwired directly into your home's electrical system, go to your main breaker panel and switch off the circuit breaker labeled for the garbage disposal or kitchen outlets.

Step 2: Let the Unit Cool Down

If the motor has overheated, the thermal switch will not reset immediately. If you try to press the red button while the unit is still hot, it will simply pop right back out. Give the disposal 10 to 15 minutes to cool down completely. Use this time to grab a flashlight and clear out any items stored under your sink so you have clear access to the bottom of the unit.

Step 3: Locate and Press the Red Reset Button

Crawl under the sink and look at the very bottom of the garbage disposal unit (the side facing the cabinet floor). You will see a small, round, or square red button. It is usually about the size of a pencil eraser. If the disposal has tripped, this button will be protruding outward by about a quarter of an inch (5mm). Press the button straight up and in until you hear or feel a distinct mechanical click. If it feels mushy or pops back out immediately, the unit is still too hot—wait another 10 minutes and try again.

Step 4: Inspect the Chamber for Obstructions

Before restoring power, shine your flashlight down the sink drain. Look closely at the grinding chamber. If you see any visible obstructions—like a dropped bottle cap, a piece of bone, or thick vegetable peels—use a pair of long kitchen tongs or needle-nose pliers to pull them out. Never, under any circumstances, put your bare hand inside the grinding chamber.

Step 5: Restore Power and Test with Cold Water

Plug the unit back into the outlet (or turn the circuit breaker back on). Turn on your kitchen faucet, letting a steady stream of cold water run down into the disposal. Flip the wall switch in short, quick bursts to test the unit. It should roar back to life with its normal spinning sound. Let the cold water run for another 15 to 20 seconds after turning off the disposal to flush any remaining debris down the drain.

How to reset a garbage disposal safely: Powering down first

We cannot emphasize the importance of electrical safety enough. The grinding chamber of a garbage disposal is a damp, metallic environment, making it a prime conductor for electricity.

Before you even think about looking under the sink or touching the reset button, you must verify that the power is completely cut. Flipping the wall switch to "OFF" is a good start, but switches can sometimes fail or be accidentally bumped by a family member or pet while you are working underneath.

If you are planning to do any troubleshooting beyond a simple button press—such as inserting tools to clear a jam—unplugging the unit is the only way to guarantee your safety. If your unit is hardwired and lacks a plug, locating the correct circuit breaker in your electrical panel is mandatory. For local Virginia homeowners, ensuring your kitchen electrical connections are up to code is a key part of maintaining a safe home.

Troubleshooting and Preventive Maintenance Tips

What happens if you press the reset button, restore power, flip the switch, and all you hear is a low, struggling humming sound?

A humming sound without grinding means your disposal is getting electricity, but the rotating flywheel is mechanically locked in place. If you let it hum for more than a few seconds, the motor will overheat again, and the red reset button will trip once more to protect the motor from burning out.

To clear a stubborn mechanical jam, follow these troubleshooting steps:

• Use the Hex Key (Allen Wrench) Method: Almost all modern garbage disposals (including InSinkErator, Moen, and Waste King) feature a small, hexagonal hole in the center of the bottom of the unit. This socket connects directly to the motor's drive shaft. Insert a 1/4-inch Allen wrench (often called a "jam buster wrench") into this hole.
• Manually Rotate the Flywheel: Firmly work the wrench back and forth in a clockwise and counterclockwise direction. At first, it might feel completely stuck. Apply steady, moderate pressure until the wrench moves freely in both directions. This manual rotation breaks the jam and frees up the impeller plate.
• Clear the Debris: Once the flywheel spins freely with the wrench, look down the drain with a flashlight. Use tongs to remove the freed obstruction.
• Reset and Test: Press the red reset button on the bottom, run cold water, and flip the switch to test.

Once your disposal is working beautifully again, you will want to keep it that way! Here are some of our favorite preventative maintenance tips to keep things spinning smoothly:

• The Cold Water Rule: Always run cold water before, during, and for at least 15 to 20 seconds after running your disposal. Cold water is crucial because it solidifies any grease or fats that sneak down the drain, allowing the blades to chop them into solid particles. Hot water melts grease, which then flows further down your pipes, cools, solidifies, and creates stubborn sewer line clogs.
• Know What to Avoid: Your disposal is not a trash can. Avoid putting fibrous vegetables (celery, corn husks, asparagus), starchy foods (pasta, rice, potato peels), coffee grounds, eggshells, large bones, and grease down the drain. These items are notorious for wrapping around the impeller plate or forming paste-like clogs.
• Clean with Ice and Salt: Once a month, pour two cups of ice cubes and one cup of coarse rock salt down the disposal. Run cold water and turn the unit on. The grinding of the hard ice and abrasive salt scrubs the blades, removes built-up slime, and knocks away stuck-on food debris.
• Deodorize with Citrus: To keep things smelling fresh, grind up a few small lemon, lime, or orange peels. The natural citric acid neutralizes bad odors and leaves your kitchen smelling clean.

How to reset a garbage disposal safely when it keeps tripping

If you find yourself reaching under the sink to press that red button every single time you do the dishes, you have an underlying issue. A garbage disposal that constantly trips is trying to tell you something.

Persistent tripping usually points to one of three issues:

1. An Unresolved Jam: There might be a small, hard object (like a fragment of glass or a tiny bone) wedged deep beneath the impeller plate. It might allow the disposal to spin for a second or two before locking it up again, causing the motor to overheat and trip the switch.
2. Motor Wear and Aging: Like all mechanical appliances, garbage disposals have a natural lifespan—typically between 8 to 12 years. As the motor ages, its internal electrical windings degrade. The motor has to draw more electrical current to achieve the same grinding power, which leads to rapid overheating and constant tripping.
3. Internal Electrical Shorts: Over time, the internal seals of a disposal can wear out, allowing water to slowly drip into the electrical motor compartment. This creates a direct short circuit, causing the thermal switch or your home's GFCI outlet to trip instantly for safety.

If your aging unit is constantly giving you trouble, it might be time to start exploring replacement options.

Frequently Asked Questions about Garbage Disposal Resets

Where is the reset button located on most garbage disposals?

On almost all residential garbage disposals, the reset button is located on the very bottom of the unit, facing the cabinet floor. It is typically a small, red, circular or square button about the size of a pencil eraser. On some older models, it may be located near the bottom edge on the side of the outer plastic shell. If you are having trouble finding it, use a flashlight and a small hand mirror to get a clear view of the disposal's underside.

What if my garbage disposal does not have a reset button?

While the vast majority of modern disposals have a built-in red reset button, some older or specialty models do not. If your unit lacks this button, look for other safety reset points. Check the GFCI (Ground Fault Circuit Interrupter) outlet under your sink or along your kitchen backsplash. If the outlet's "RESET" button has popped out, press it back in. If that doesn't work, head to your home's main electrical panel and check for a tripped circuit breaker. Flip the breaker completely to the "OFF" position, then back to "ON."

When should I call a professional plumber?

While a basic reset or simple jam is easy to handle on your own, some situations require professional expertise. You should call a licensed plumber if:

• The unit is leaking from the bottom: Water dripping from the bottom of the disposal means the internal motor seals have failed. This is not repairable and requires a new unit installation.
• You smell burning or see smoke: This indicates a serious electrical short or a completely burned-out motor. Turn off the power immediately and do not attempt to run the unit.
• The disposal hums but the flywheel won't budge: If you have tried using an Allen wrench and the plate is completely seized, the bearings may have failed.
• The unit keeps tripping the breaker immediately after a reset: This points to an electrical fault in the wiring or the motor.

If you are facing any of these issues, it is always safest to call in the experts. Learn more about our professional Garbage Disposal Repair and Installation services to get your kitchen back on track safely.
