How to Fix a Humming or Jammed Garbage Disposal · Step 5 of 5
This guide provides comprehensive, step-by-step instructions for diagnosing and fixing a common plumbing issue: a garbage disposal that is humming but not spinning. The process involves ensuring safety by disconnecting power, visually inspecting and clearing obstructions from the top, using a specialized wrench to manually free the jammed motor from below, resetting the unit's overload protector, and finally testing for proper operation.

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.
