Yes, most garbage disposals have a reset button, and it's usually on the bottom

Your garbage disposal almost certainly has a reset button, and it's designed to trip when the motor gets too hot or when the unit jams. The button is a red or black cylinder about the size of a pencil eraser, located on the underside of the disposal unit itself—not on the wall switch or in the sink. When the disposal shuts down unexpectedly, the reset button has usually popped out, and pushing it back in is often all you need to do to get the unit running again.

The reset button is a safety feature, not a repair tool. It cuts power to the motor when something goes wrong, protecting both the machine and you. Understanding where it is and how to use it can save you a service call for problems you can solve in under a minute.

Key Takeaways

  • The reset button is a small cylinder on the bottom of the disposal unit, not on the switch or counter.
  • The button pops out when the motor overheats or the disposal jams, cutting power automatically.
  • Push the button back in to restore power, but only after you have cleared whatever caused the jam.
  • If the button pops out again when ready or repeatedly, the disposal may have a serious problem and you should call a plumber.
  • Never reach into the sink or try to force the disposal to run while the button is out.

How to locate the reset button on your disposal

Get a flashlight and look at the bottom of the disposal unit, which hangs under your sink. The reset button is mounted on the side or bottom of the cylindrical motor housing. It will be red or black and protrudes slightly from the surface. If you have a newer disposal, the button may be harder to see because manufacturers sometimes make it flush with the housing.

If you cannot find it, check your disposal's manual or look up the model number (usually stamped on the side of the unit). The manual will show you exactly where the button is on your specific model. Some disposals have the button in slightly different locations depending on the brand and age of the unit.

Why the reset button trips and what it means

The reset button pops out for two main reasons: the motor has overheated, or the disposal has jammed and the motor is working too hard. When the button trips, it breaks the electrical circuit and stops the motor from running. This protects the motor from burning out and protects you from the disposal suddenly starting while you are working on it.

Overheating usually happens when the disposal runs for too long without a break, when the drain is blocked and water backs up into the unit, or when the motor itself is failing. A jam happens when something hard or fibrous gets stuck between the grinding ring and the impellers—the spinning parts inside the disposal.

Steps to reset your disposal safely

Before you touch the reset button, turn off the wall switch and make sure the disposal is not running. Wait a few minutes for the motor to cool down if it has been running.

Next, look into the sink drain with a flashlight. If you can see something stuck—a bone, a piece of plastic, a fruit pit, or a tangle of fibrous material—remove it with tongs or pliers. Do not put your hand down the drain. If you cannot see anything obvious, use a plunger on the sink to try to dislodge whatever is blocking the drain.

Once you have cleared what you can see, locate the reset button on the bottom of the unit and push it firmly until it clicks back into place. Then turn the wall switch back on and run cold water while you turn on the disposal briefly to test it. If it runs smoothly, the problem is solved.

When the reset button keeps popping out

If the button pops out again within a few minutes, or if it pops out repeatedly even after you have cleared visible jams, the disposal has a problem that resetting will not fix. This usually means the motor is failing, the impellers are damaged, or there is a blockage deeper in the drain line that you cannot reach from the sink.

At this point, call a plumber. Continuing to reset the button and run the disposal will only make the problem worse and may damage the motor beyond repair. A plumber can use a drain snake to clear a deep blockage, or they can determine whether the disposal itself needs to be replaced.

Preventing jams and overheating

Run cold water before, during, and after using the disposal. Cold water helps solidify grease so it breaks apart instead of coating the impellers. Avoid putting fibrous materials like celery, corn husks, or onion skins down the disposal—these wrap around the impellers and cause jams. Do not put bones, pits, or hard shells in the disposal either.

Never run the disposal for more than a minute or two at a time. If the disposal is still grinding after 30 seconds, turn it off and let it cool. Continuous running heats up the motor and can trip the reset button even if there is no jam. Empty the sink strainer regularly so food does not back up and block the drain.

What to do if you cannot find the reset button

Some older disposals or certain brands do not have a reset button. If you have looked carefully at the bottom of the unit and cannot find one, check the manual or search online for your model number and the word "reset." You may find that your disposal uses a different safety mechanism, such as a thermal overload switch that resets on its own after cooling, or a breaker on the electrical outlet.

If your disposal straightforward stopped working and you cannot find a reset button, the problem may be electrical. Check that the wall switch is on and that the outlet has power. If the outlet is controlled by a GFCI breaker (common in kitchens), press the reset button on the outlet itself. If none of these steps work, call a plumber or electrician.

Frequently Asked Questions

Can I reset the disposal while it is still plugged in?

Yes, the reset button is safe to push while the disposal is plugged in. However, always turn off the wall switch first so the motor is not running. Never reach into the sink or touch the impellers while the disposal is plugged in, even if the switch is off.

What if the reset button is stuck and won't pop back in?

If the button resists when you push it, stop and do not force it. A stuck button usually means the motor is still too hot or there is still a jam. Wait 10 to 15 minutes for the motor to cool, clear any visible blockage again, and try once more. If it still will not click into place, call a plumber.

Does resetting the disposal fix a leak?

No. The reset button only restores power to the motor. If your disposal is leaking from the bottom or from the connection to the sink, resetting it will not stop the leak. You will need a plumber to repair or replace the unit.

How often should the reset button pop out?

Under normal use, the reset button should rarely or never pop out. If it trips once every few months, it is usually a one-time jam or a temporary overheating. If it pops out weekly or more often, something is wrong with the disposal or the drain, and you should have a plumber inspect it.
