How to Fix a Humming or Jammed Garbage Disposal · Step 4 of 5
In this video
If your garbage disposal suddenly stops working and makes no noise, the first thing to check is the reset button. Look on the very bottom of the disposal unit, which is located under your sink. You will find a small, typically red, button. This is the overload protection reset. Firmly press this button in. You may hear or feel a slight click. This action resets the internal circuit breaker of the motor. After pressing the button, try turning the disposal on again.
Goal: Reset the garbage disposal's internal motor protection
- The reset button often trips when the motor is overloaded, for instance, from grinding something too hard or running the disposal for too long.
- Ensure the garbage disposal switch is turned off before you reach under the sink to find the button.

FAQs
Why is it crucial to disconnect power before working on the garbage disposal, and what's the safest way to do it?
Disconnecting power is essential for your safety to prevent accidental activation and electrical shock. Always turn off the circuit breaker that controls the disposal, not just the wall switch, and consider testing with a voltage tester if unsure. This ensures the unit cannot unexpectedly start while your hands are near the grinding chamber.
Do I need a special tool to manually free the jammed motor, or can I use a standard wrench?
Most garbage disposals come with a specific hex-head wrench (often called an Allen wrench or jam-buster wrench) designed to fit the bottom center hole. If you don't have this, a 1/4-inch hex Allen wrench or the specific Klein Tools socket mentioned in the project can often be used to manually turn the motor shaft from the bottom of the unit. Using the correct tool ensures a proper fit and prevents stripping the opening.
I've cleared the grinding chamber and pressed the reset button, but my disposal is still humming. What should I do next?
A humming sound after clearing and resetting indicates the motor is still trying to turn but is stuck. The next step is to manually free the jammed motor using the hex-head wrench from the bottom of the disposal. Insert the wrench into the center hole and turn it back and forth several times to dislodge any remaining obstruction or free the impellers.
This project is listed as 'beginner,' but what if I'm uncomfortable working with plumbing or electricity? When should I call a professional?
While this is a common beginner DIY fix, if you're uncomfortable with basic electrical safety (turning off circuit breakers) or reaching into the disposal's grinding chamber, it's always best to call a licensed plumber. If the disposal hums even after clearing jams, manually freeing the motor, and resetting the button, or if you suspect an electrical issue beyond a simple reset, professional help is warranted.
