If your garbage disposal suddenly stops working, don’t panic — the problem may be much easier to fix than you think.
Many garbage disposals include a built-in reset button designed to protect the motor from overheating, overloading, or jamming.
In many cases, pressing this reset button can restore power and get the disposal running again within minutes.
In this guide, we’ll explain how to reset a garbage disposal safely, where to find the reset button, and what to do if the disposal still won’t work afterward.

What Does the Garbage Disposal Reset Button Do?
The reset button acts as a safety feature for the garbage disposal motor.
If the disposal becomes overloaded or overheats, the unit may automatically shut off to prevent internal damage.
When this happens, the reset button will usually trip outward slightly underneath the disposal.
Pressing the button resets the internal overload protection and allows the disposal to restart.
Where Is the Reset Button on a Garbage Disposal?
On most garbage disposals, the reset button is located: underneath the disposal unit
The button is usually:
- small
- round
- red
You may need a flashlight to see it clearly under the sink.
How to Reset a Garbage Disposal
Resetting a garbage disposal is usually very simple and only takes a few minutes.
- Step 1 — Turn Off the Disposal
Before touching the unit, make sure the garbage disposal switch is turned off completely.
This helps reduce the risk of injury while working underneath the sink.
- Step 2 — Locate the Reset Button
Look underneath the disposal unit for the red reset button.
If the button has popped outward, the disposal has likely triggered its overload protection.
- Step 3 — Press the Reset Button
Firmly press the reset button inward until it clicks.
If the button stays in place, the disposal has been reset successfully.
- Step 4 — Turn the Power Back On
Run cold water and switch the disposal back on to test it.
If the disposal operates normally again, the issue was likely caused by a temporary overload or jam.
Why Do Garbage Disposals Need Resetting?
Garbage disposals often trip their reset button when:
- too much food waste is added at once
- hard food scraps jam the grinding plate
- the motor overheats
- the disposal becomes overloaded
Lower-powered garbage disposals may trip more often when handling heavier food waste.
You can compare the most powerful garbage disposals if your current unit struggles regularly.
What If the Garbage Disposal Still Won’t Work?
If the disposal still doesn’t turn on after resetting, there may be another issue causing the problem.
Common possibilities include:
- jammed grinding plate
- electrical problems
- damaged motor
- clogged internal components
One of the most common causes is a jam inside the disposal.

How to Prevent Garbage Disposal Overloads
You can reduce the chances of needing future resets by:

FAQ'S
Why did my garbage disposal suddenly stop working?
The disposal may have overheated, overloaded, or become jammed, causing the reset button to trip.
Is it safe to press the reset button?
Yes, as long as the disposal power is turned off first.
Why does my garbage disposal keep tripping the reset button?
Frequent resets may indicate:
- motor strain
- repeated jams
- insufficient motor power
- aging internal components
Can a jam stop the disposal from resetting?
Yes. A jammed grinding plate can prevent the motor from operating correctly even after resetting.
Final Verdict
Knowing how to reset a garbage disposal is one of the easiest ways to troubleshoot a disposal that suddenly stops working.
In many cases, simply pressing the reset button can restore normal operation in just a few minutes.
However, if the disposal repeatedly overheats, jams, or struggles during normal use, it may be time to inspect the unit further or consider replacement.
