Why Your Garbage Disposal Needs a Reset

A garbage disposal stops working for one of two reasons: the motor has overheated and shut itself off, or the unit has tripped its internal reset button. Both are safety features. When the motor gets too hot—usually because something is jamming the blades—the disposal cuts power automatically. The reset button does the same thing if the motor draws too much current. In either case, you cannot restart the unit by flipping the wall switch. You have to physically press the reset button, which is a small red or black button on the bottom or side of the disposal unit itself.

Resetting takes about two minutes and requires no tools. The most important step is making sure the jam is actually cleared before you reset, or the motor will overheat again when ready.

Key Takeaways

  • The reset button is located on the bottom or lower side of the disposal unit under the sink, not on the wall switch.
  • Always turn off the wall switch and unplug the disposal before you reach into it or press the reset button.
  • Remove any visible jam with tongs or pliers—never put your hand down the drain—before attempting a reset.
  • Press the reset button firmly until you hear or feel a click, then wait 5 minutes before turning the unit back on.
  • If the disposal trips again within a few minutes, the jam may not be fully cleared or the motor may need professional inspection.

Locate the Reset Button on Your Unit

The reset button is mounted directly on the garbage disposal housing, not on the wall or counter. On most models, it sits on the bottom of the unit, centered between the drain opening and the motor. On some older or compact models, it may be on the side. Look for a small button, usually red or black, about the size of a pencil eraser. It will stick out slightly from the metal casing.

If you cannot find it, check your disposal's manual or look up the model number (usually stamped on the housing) online. The manual will show you exactly where the button is on your specific model. Some disposals have the button recessed slightly, so you may need to feel for it with your finger rather than see it clearly.

Turn Off Power and Clear the Jam

Before you touch anything inside the disposal, turn off the wall switch and unplug the unit from the outlet under the sink. Do not rely on the switch alone—unplugging removes all power and prevents the motor from starting accidentally while your hand is near the drain. Wait 30 seconds after unplugging to let any residual charge drain from the motor.

Use a flashlight to look down the drain and identify what is stuck. Common culprits are bones, fruit pits, fibrous vegetables like celery, or plastic. Use needle-nose pliers or kitchen tongs to pull out the jam. Never put your hand into the disposal, even when it is off. If you cannot reach the jam with pliers, you may need to disassemble the unit or call a plumber—do not force anything.

Once the jam is out, run water down the drain for a few seconds to rinse away any remaining debris. This step matters: if particles are still lodged in the impellers, the motor will jam again as soon as you reset.

Press the Reset Button and Wait

Locate the reset button and press it firmly with your finger or thumb. You should feel or hear a distinct click. The button may pop back out slightly after you release it—this is normal. If the button does not click or move at all, it may already be in the reset position, or the unit may have a different reset mechanism (check your manual).

After pressing the button, wait at least 5 minutes before turning the disposal back on. This gives the motor time to cool down if overheating was the cause. Do not plug the unit back in or flip the switch during this waiting period.

Restore Power and Test the Disposal

Plug the disposal back into the outlet under the sink. Turn on the wall switch. The unit should start normally. Run cold water down the drain for 10 to 15 seconds while the disposal is running to test it. If it runs smoothly without grinding sounds or vibration, the reset was successful.

If the disposal starts but makes a grinding or rattling noise, turn it off when ready and unplug it again. This usually means a small piece of the jam is still stuck. Repeat the clearing process with pliers before attempting another reset.

What to Do If the Reset Does Not Hold

If the disposal trips again within a few minutes of running, the problem is not a one-time jam. This usually means either a piece of the jam is still stuck deeper in the unit, or the motor itself is failing. Do not keep pressing the reset button repeatedly—this can damage the motor further.

Try one more time: unplug the unit, use pliers to clear the drain thoroughly, and look for any debris caught in the impeller blades themselves (you may need to rotate the blades slightly by hand to dislodge something). If it trips again after a full clearing, the motor or reset mechanism may be worn out, and the unit will likely need to be replaced or serviced by a professional.

Prevent Future Jams and Resets

Most garbage disposal resets happen because of what goes down the drain. Avoid putting bones, fruit pits, pasta, rice, grease, or fibrous vegetables like celery or corn husks into the disposal. These items either jam the blades or expand and clog the drain line. Run cold water while the disposal is operating and for 10 seconds after you turn it off—this flushes debris through the system.

If you have a septic system rather than a municipal sewer, use the disposal sparingly or not at all. Septic tanks are designed to handle human waste and toilet paper, not food solids, and a disposal can overload the system. Check your septic documentation or ask your septic service provider before using a disposal regularly.

Frequently Asked Questions

Can I reset the disposal without unplugging it?

No. Always unplug the unit before pressing the reset button or reaching into the drain. Even with the wall switch off, the motor can start unexpectedly if you touch the reset button while the unit is plugged in. Unplugging takes 10 seconds and prevents serious injury.

What if the reset button is stuck and won't click?

A stuck button usually means the motor is still too hot or the reset mechanism is jammed. Unplug the unit and wait 10 to 15 minutes for the motor to cool completely. Try pressing the button again with steady, firm pressure—do not force it or tap it with a tool. If it still will not click, the reset mechanism may be broken and the unit may need replacement.

Is it normal for the disposal to smell bad after a reset?

Yes, especially if food was stuck in the unit for a while. Run cold water and the disposal together for 20 to 30 seconds to flush out any decomposing debris. If the smell persists, pour half a cup of baking soda down the drain, followed by a cup of white vinegar, and let it sit for 30 minutes before running water and the disposal again.

How long should I wait after pressing reset before using the disposal?

Wait at least 5 minutes. This allows the motor to cool if overheating caused the trip. You can plug the unit back in after 5 minutes, but run water through it for 10 to 15 seconds before putting food waste down the drain.

Can a reset button wear out?

Yes. If your disposal trips and resets frequently—more than once a month—the reset mechanism may be wearing out, or the motor may be failing. Frequent resets are a sign that the unit is working too hard and may need professional service or replacement soon.
