In this video

With the power safely disconnected, carefully reach into the murky water in the sink and feel inside the garbage disposal's grinding chamber for any obvious, large obstructions. The video's narrator mentions finding popcorn kernels in his disposal. Using a pair of tongs or pliers is a safer method than using your bare hands to avoid potential cuts.

Goal: Remove any large debris from the grinding chamber

  • Be cautious of sharp blades inside the disposal, even with the power off.
  • Using a flashlight can help you see inside the drain to identify the obstruction.

FAQs

What is the most crucial safety step before I start, and why?

The most crucial safety step is to ALWAYS disconnect power to the garbage disposal at your home's circuit breaker before performing any work. This prevents the unit from accidentally turning on, which could lead to severe injury while your hands or tools are inside the disposal.

My disposal is humming but not grinding; does this mean it's jammed, and how is that different from a complete jam?

Yes, a humming disposal almost always indicates it's jammed. The motor is receiving power but cannot turn the grinding plates due to an obstruction. A 'complete jam' means the motor isn't even humming, often indicating the reset button has tripped due to overload.

Do I need all the specific tools listed, like the specialized wrench, or are there alternatives for clearing a jam?

While the project lists a general wrench and a precision screwdriver, the most critical tool for freeing a jam from below is a 1/4-inch hex key or Allen wrench, which often comes with new disposals. A strong flashlight like the Panther Vision FLATEYE is highly recommended for visibility, and tongs or pliers are great for removing items from above instead of your hand.

I've pressed the reset button, but my disposal still won't work or just hums again. What should I do next?

If the reset button immediately trips again or the disposal hums but doesn't spin, it likely means the obstruction hasn't been fully cleared, or there's a more serious electrical issue. Go back to step 3 to thoroughly ensure no items are obstructing the grinding plates and try manually turning the flywheel again with the hex key. If problems persist, it might be time to call a plumber.
