Yes, most garbage disposals have a reset button on the bottom or side of the unit

The reset button is a small red or black button, usually located on the underside or lower side of the disposal motor housing. It sits separate from the main power switch on your wall. This button cuts power to the motor when the disposal jams or overheats, and pressing it restarts the unit after you have cleared the blockage.

Not every disposal has a reset button — older models and some compact units skip it entirely. If you cannot find one after checking the bottom and sides of the motor housing, your model likely does not include this safety feature. In that case, you will need to flip the wall switch off and on instead, or check your manual for the specific restart procedure.

The reset button exists to protect you. When something jams the blades, the motor draws extra current and the button pops out automatically, cutting power before the motor overheats or burns out. This is a safety feature, not a convenience — it means the disposal shut itself down for a reason.

Key Takeaways

  • The reset button is a small colored button on the bottom or lower side of the disposal motor, separate from your wall switch.
  • The button pops out when the motor overheats or jams, and you must clear the blockage before pressing it back in.
  • Never reach into the disposal while it is plugged in, even if the motor is off — always unplug it first or flip the breaker.
  • If the reset button pops out repeatedly after you clear the jam, the motor may be failing and the unit may need replacement.
  • Some older disposals do not have a reset button; check your manual or the manufacturer's label on the unit for your model's restart procedure.

How to locate the reset button on your specific disposal

Start by looking directly underneath the disposal motor housing. Shine a flashlight up from below the sink to see the bottom clearly. The reset button is usually a small cylinder about the size of a pencil eraser, often red or black, and it sticks out slightly from the housing. It may be labeled "reset" or just marked with a small dot.

If you do not see it on the bottom, check the sides of the motor housing, especially the side facing the wall or cabinet. Some models place the button on the lower front or back. Run your fingers around the entire lower half of the motor casing — the button will feel like a small raised bump.

If you still cannot find it, look for a label or model number on the disposal itself. The label usually appears on a sticker attached to the motor housing. Write down the brand and model number, then search online for the manual or a diagram. The manufacturer's documentation will show you exactly where the button is, or confirm that your model does not have one.

What to do before you press the reset button

Before touching the reset button, you must stop the jam. Turn off the wall switch and wait at least 30 seconds for the blades to stop completely. Do not reach into the disposal with your hands — use tongs, pliers, or a wooden spoon to fish out whatever is stuck. Common culprits are bones, fruit pits, fibrous vegetables like celery, and utensils that fell in accidentally.

Once you have removed the blockage, run cold water into the disposal for 10 to 15 seconds to clear any remaining debris. Then turn the wall switch back on briefly — just for a second — to see if the motor runs freely. If it does, turn it off again. If it still sounds stuck or grinding, turn it off and remove more material.

Only after the blades spin freely should you press the reset button. If the button is already popped out, straightforward push it back in firmly until you hear or feel a click. Then flip the wall switch on to restart the disposal. Run cold water while it runs for a few seconds to make sure everything is working normally.

Why the reset button pops out and what it means

The reset button is a thermal overload switch. When the motor draws too much current — usually because the blades are jammed — the internal temperature rises. Once it reaches a certain threshold, a metal strip inside the switch bends and breaks the electrical circuit, popping the button out. This prevents the motor from burning out or catching fire.

A jammed disposal is the most common reason the button pops. Bones, pits, and fibrous materials like onion skins or corn husks wrap around the blades and lock them up. Less often, the button pops because the motor itself is wearing out and drawing more current than it should, even without a jam.

If the reset button pops out when ready after you press it, or pops out repeatedly within a few days, the motor is likely failing. A functioning disposal should run for years without the button popping unless you jam it. Repeated popping means the motor is struggling and will probably need to be replaced soon.

Safety steps when dealing with a jammed disposal

Always unplug the disposal or flip the breaker switch before you put anything into it, even if the motor is off. The wall switch only controls power to the motor — it does not lock the blades in place. If someone accidentally flips the switch while your hand is inside, the blades will start and cause serious injury.

Use a wooden spoon, tongs, or needle-nose pliers to reach into the disposal. Never use your fingers or a cloth. If something is truly stuck and you cannot remove it with tools, stop trying. Call a plumber instead. Forcing it risks breaking the blades or the motor, and the cost of a service call is far less than the cost of a new unit.

Never pour chemical drain cleaners into a garbage disposal. These products can damage the rubber seals and metal components, and they create toxic fumes if mixed with other substances. If the disposal is clogged below the trap, use a plunger on the sink or call a plumber — do not use chemicals.

What to do if your disposal has no reset button

Older disposals and some compact models do not include a reset button. If yours does not have one, the way to restart after a jam is to turn off the wall switch, clear the blockage, and then flip the switch back on. The disposal will restart without any additional step.

Check your manual to see if your model has any special restart procedure. Some disposals have a small hex wrench that fits into a socket on the bottom of the motor — you can use this to manually turn the blades and free up a jam before you turn the power back on. If your manual mentions this, keep the wrench in a drawer near the sink so you have it when you need it.

If you cannot find your manual, search online using the brand and model number from the label on the unit. Most manufacturers post manuals as free PDFs, and the document will tell you exactly how to handle a jam on your specific model.

When to replace your disposal instead of resetting it

A disposal that jams frequently — more than once a month — is a sign that you are putting the wrong things down it, or that the unit is wearing out. If you have changed your habits and still see frequent jams, the blades or motor may be deteriorating. Replacement is usually cheaper than repeated service calls.

If the reset button pops out and will not stay in, or if the motor makes a loud grinding or squealing noise even after you clear the jam, the unit is likely at the end of its life. Most disposals last 8 to 15 years depending on use and maintenance. If yours is older than 10 years and having problems, replacement is usually the practical choice.

A new garbage disposal costs between $150 and $500 depending on the brand and horsepower, plus installation labor if you hire a plumber. If your current unit is old and failing, investing in a new one will save you money and frustration compared to repeated repairs.

Frequently Asked Questions

Can I press the reset button without clearing the jam first?

No. The reset button will pop back out when ready if the jam is still there, because the motor will draw too much current again as soon as it tries to run. You must remove the blockage first, run water to clear debris, and confirm the blades spin freely before pressing reset.

What if the reset button is stuck and will not pop back in?

Turn off the wall switch and unplug the disposal. Let it cool for 15 to 20 minutes — the button may be stuck because the motor is still hot. Then try pressing it again gently but firmly. If it still will not click in, the internal switch mechanism may be damaged and the unit may need replacement.

Is it safe to use the disposal if the reset button keeps popping out?

No. Repeated popping means the motor is overheating or drawing too much current. Using it anyway risks a fire or complete motor failure. Stop using it and call a plumber or the manufacturer to discuss whether repair or replacement is the right choice.

Where exactly is the reset button if I cannot find it on the bottom?

Check the lower sides of the motor housing, especially the side closest to the wall or cabinet. Some models place it on the front or back lower edge. If you have looked everywhere and cannot find it, your model likely does not have one — check your manual or search online for your brand and model number.

Do I need to turn off the wall switch before pressing the reset button?

Yes. Always turn off the wall switch first, clear the jam, and confirm the blades move freely. Then press the reset button. After that, you can flip the wall switch back on to restart the disposal. This order keeps you safe and ensures the motor does not try to run while something is still blocking it.
