How to Reset a Garbage Disposal Safely 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 service call and get your kitchen back to normal in minutes. Here’s the quick answer:

How to reset a garbage disposal safely:

1. Turn off the power at the wall switch and unplug the unit or flip the circuit breaker.
2. Wait 10–15 minutes for the motor to cool down completely.
3. Check for obstructions using a flashlight — remove any debris with tongs, never your hand.
4. Locate the reset button on the bottom of the unit (usually a small red or black button).
5. Press the reset button firmly until you feel or hear it click into place.
6. Restore power and test by running cold water first, then switching the unit on.

If the button pops back out immediately, the motor may still be too hot or a jam hasn’t been fully cleared. Give it another 10 minutes and try again.

Garbage disposals are one of the most convenient appliances in a modern kitchen — until they suddenly go quiet or start humming without grinding. The good news is that more than 80% of garbage disposal issues can be resolved by simply pressing the reset button, no plumber required. That little button on the bottom of your unit is actually a built-in thermal overload protector. When the motor overheats from a jam, extended run time, or an overloaded grind, it trips automatically to prevent permanent damage — much like a mini circuit breaker. The problem isn’t usually a broken disposal. It’s a motor that needs a moment to cool down and a reset to get back on track.

Essential Safety Precautions and Tools Needed

Before we start poking around under the kitchen sink, let’s talk about safety. A garbage disposal is a powerful motorized appliance designed to shred tough food waste. Even when it seems completely dead or silent, you must treat it with absolute respect. Mechanical parts can suddenly spring back into action if power is restored unexpectedly.

For a comprehensive look at the mechanics under your sink, check out our Garbage Disposal Reset Button Complete Guide. Here are the primary safety rules we live by at Flow Pro Plumbing:

• Completely Disconnect the Power: Turning off the wall switch is step one, but do not stop there. Unplug the disposal from the electrical outlet underneath your sink. If your disposal is hardwired directly into the wall, locate your home’s main electrical panel and switch off the dedicated circuit breaker for the disposal.
• Keep Your Hands Out of the Chamber: Never, under any circumstances, insert your bare hands or fingers into the grinding chamber. Even if the power is disconnected, sharp metal impellers or wedged debris can shift suddenly and cause severe injury.
• Keep the Workspace Dry: Before crawling under the sink, inspect the area for any active moisture or leaks. Wipe up any standing water to avoid slipping or creating an electrical hazard while working near outlets.
• Improve Visibility: The space under your kitchen sink is notoriously dark and cramped. Use a bright flashlight or a headlamp to clearly see the bottom of the unit and inside the drain.

Tools to Gather Before You Begin

You won’t need an expensive plumbing kit to handle this job. In fact, most of these items are already sitting in your garage or utility drawer:

1. Flashlight: To inspect the interior grinding chamber and find the reset button underneath the unit.
2. Long Kitchen Tongs or Needle-Nose Pliers: To safely extract wedged objects (like a stray cherry pit or a fallen teaspoon) from the drain.
3. 1/4-Inch Allen Wrench (Hex Key): Most standard disposals (including InSinkErator, Moen, and Waste King models) feature a small hex socket on the very bottom of the motor housing. This wrench is used to manually rotate the motor shaft and break free tough jams.
4. Safety Goggles & Work Gloves: To protect your eyes from splashes and your hands from any hidden sharp edges under the sink.

How to Reset a Garbage Disposal Safely in 5 Steps

If your disposal has suddenly shut off and won’t make a sound when you flip the switch, the internal circuit breaker has likely tripped. Follow this simple, safe process to get it running again. For more detailed troubleshooting on this specific feature, you can read our guide on the Garbage Disposal Reset Button.

Why Knowing How to Reset a Garbage Disposal Safely Prevents Motor Damage

The reset button is your disposal’s first line of defense. When a foreign object jams the impellers or the motor runs for too long, the electrical resistance increases, generating intense heat. To prevent the motor windings from melting or catching fire, the built-in thermal overload protector interrupts the electrical circuit, instantly cutting power.

Understanding how to reset a garbage disposal safely ensures you don’t bypass this critical safety feature. Trying to force a jammed, overheated motor to run without resetting and clearing the issue first can permanently burn out the motor, forcing you to purchase a brand-new unit.

Step-by-Step: How to Reset a Garbage Disposal Safely When It Overheats

Step 1: Shut Down All Power

Flip the wall switch to the “OFF” position. Go beneath the sink and unplug the disposal’s power cord from the wall outlet. If your unit is hardwired, switch off the breaker at your main electrical panel.

Step 2: Let the Motor Cool Down

If the disposal was running right before it shut off, the motor will be hot. Wait 10 to 15 minutes. This cooling period is crucial; if you attempt to reset the thermal protector while the bi-metal switch inside is still hot, the button will simply pop right back out, and the circuit won’t close.

Step 3: Inspect the Grinding Chamber

Shine your flashlight down the sink drain. Look closely at the grinding plate and outer ring. If you see any obvious obstructions — like a bone, a bottle cap, or fibrous vegetable scraps — use your long kitchen tongs or needle-nose pliers to carefully lift them out.

Step 4: Locate and Press the Reset Button

Reach under the sink and feel around the bottom of the garbage disposal housing. You are looking for a small, square or circular button that is usually red or black. It is typically about the size of a pencil eraser. When tripped, this button will protrude downward by about a quarter of an inch (5mm). Press it straight up firmly until you hear or feel a distinct click.

Step 5: Restore Power and Perform a Controlled Test

Plug the unit back in (or turn the circuit breaker back on). Turn on your kitchen faucet and let a steady stream of cold water run down the drain. Flip the wall switch on for a brief second to test. If the unit runs smoothly, let the water run for another 10 seconds to flush out any remaining debris, and you’re good to go!

How to Manually Rotate the Flywheel to Clear a Jam

What happens if you press the reset button, flip the switch, and all you hear is a low, humming sound? Or worse, what if the reset button immediately pops back out?

A humming noise indicates that electrical power is reaching the motor, but the internal flywheel is physically jammed and cannot spin. Roughly 70% of garbage disposal jams are caused by improper items being placed in the unit. If left humming for more than a few seconds, the motor will quickly overheat and trip the reset button again.

To fix this, you need to manually rotate the flywheel to break the jam free. If your disposal is humming but won’t grind, read our comprehensive guide on Garbage Disposal Humming Not Working or check out what to do if your Garbage Disposal Won’t Drain.

Here is how to clear the jam manually using the bottom hex socket:

1. Disconnect the Power: Once again, ensure the wall switch is off and the unit is completely unplugged.
2. Locate the Hex Socket: Look at the center of the very bottom of the disposal unit under your sink. You will see a small recessed hole designed to fit a 1/4-inch Allen wrench (often called a flywheel turning wrench).
3. Insert the Allen Wrench: Insert the wrench firmly into the socket.
4. Leverage the Jam Free: Crank the wrench back and forth in both clockwise and counterclockwise directions. It might feel incredibly stiff at first. Apply steady, firm pressure until the wrench begins to turn freely in a full 360-degree circle for several revolutions. This action manually rotates the grinding plate, dislodging whatever item is wedged between the rotating impellers and the stationary grind ring.
5. Clean Out the Chamber: Shine your flashlight down the drain. The item that caused the jam has likely been dislodged and is sitting on top of the plate. Use your tongs to fish it out so it doesn’t immediately jam the unit again when you turn it back on.
6. Reset and Test: Press the red reset button on the bottom, plug the unit back in, run a heavy stream of cold water, and flip the switch to test.

Preventing Future Jams: What Never to Put Down the Drain

The absolute best way to handle a jammed garbage disposal is to prevent it from happening in the first place. Many homeowners treat their disposal like an industrial trash can, but these appliances are only designed to process light, soft food residue left over after scraping plates.

To help protect your plumbing and keep your disposal running smoothly, we put together this quick reference table of what is safe and what is highly dangerous for your system. For a deeper dive, check out our article on Why You Shouldn’t Put Food in Garbage Disposal and learn about Maintaining Your Garbage Disposal.

Item Category	Safe to Put Down Disposal?	Why or Why Not?
Soft Food Scraps	Yes	Small bits of soft fruits, cooked vegetables, and light plate scrapings break down easily.
Fats, Oils, and Grease (FOG)	NO	Grease solidifies inside your cold pipes, coating the disposal blades and creating thick, stubborn clogs downstream.
Fibrous Vegetables	NO	Celery, corn husks, artichokes, and asparagus contain long, stringy fibers that wrap around the impellers, seizing the motor.
Starchy Foods	NO	Pasta, rice, and potato peels swell up when mixed with water, forming a thick paste that jams the blades and clogs drains.
Hard Objects	NO	Animal bones, fruit pits, nut shells, and seafood shells can easily chip the grinding components or cause severe motor jams.
Non-Food Items	NO	Bottle caps, twist ties, plastic wrap, and paper towels will never break down and will instantly lock up the flywheel.
Ice Cubes & Citrus Peels	Yes	Grinding a handful of ice cubes helps scour the grinding chamber. A few small citrus peels can naturally deodorize bad smells.

Simple Habits to Protect Your Disposal

• Always Run Cold Water: Always turn on cold water before you turn on the disposal, keep it running during operation, and let it run for about 10–15 seconds after you turn the disposal off. Cold water keeps any trace fats solid so they can be chopped up and flushed away, rather than melting and coating the interior.
• Feed Scraps Slowly: Don’t stuff the disposal full before turning it on. Feed food scraps in small, gradual batches while the water is running.
• Run It Regularly: Even if you don’t have food to grind, run your disposal for a few seconds with cold water every day or two to prevent the moving parts from seizing up or rusting.

When to Call a Professional Plumber

While a simple reset or manual unjamming fixes the vast majority of garbage disposal issues, some problems require professional tools and expertise. Trying to force a failing unit to work can result in electrical hazards, severe kitchen water damage, or ruined plumbing.

You should contact us at Flow Pro Plumbing if you experience any of the following:

• Persistent Leaks: If water is dripping from the bottom of the disposal housing, the internal motor seal has failed. This cannot be repaired with putty or clamps; the unit must be replaced to prevent water damage to your cabinetry.
• The Reset Button Trips Repeatedly: If your disposal trips the reset button or your home’s circuit breaker every single time you turn it on—even when there are no physical jams or obstructions—there is likely an internal electrical short or the motor windings have failed.
• A Continuous Burning Smell: If you smell electrical smoke or a burning odor coming from under the sink, shut off the breaker immediately and do not use the unit.
• Loud, Metal-on-Metal Screeching: This usually indicates that the internal bearings have worn out, or the grinding components have completely detached.

Frequently Asked Questions About Garbage Disposal Resets

Where is the reset button located on most garbage disposals?

On almost all major brands, the red or black reset button is located on the very bottom of the garbage disposal unit, facing the cabinet floor. It is usually recessed slightly near the edge or right next to the power cord inlet. If you can’t see it clearly, use a small hand mirror or your smartphone camera to look upward at the bottom of the unit.

What should I do if the reset button won’t stay pushed in?

If you press the reset button and it immediately pops back out without clicking, it means the thermal overload switch is still too hot, or there is a persistent short circuit/jam. Wait another 15 minutes for the motor to cool down completely, verify that the flywheel can spin freely using an Allen wrench, and then try pressing the button again.

Why does my garbage disposal keep tripping the circuit breaker?

If turning on your disposal trips your home’s main electrical panel breaker rather than the little red button on the unit itself, you may have an overloaded electrical circuit, a short circuit inside the motor housing, or standing water inside the electrical connections. In some cases, worn-out blades can also cause the motor to work too hard, drawing too much current. To learn more about this, read our guide on Garbage Disposal Blade Replacement.
