Overview

Garbage disposals can stop working for several reasons, including electrical resets, jams caused by foreign objects, or mechanical blockages. Many issues can be identified by observing whether the unit is silent, humming, or partially operating.

Understanding how the disposal works can help determine whether a simple reset or manual adjustment is possible.

Common Questions Covered in the Video

Why Is My Garbage Disposal Not Turning On?

If the disposal is completely silent, the issue may be:

  • A tripped reset button

  • A power or electrical issue

  • A safety shutdown due to overheating

Why Is My Garbage Disposal Humming but Not Spinning?

A humming sound usually indicates the motor is receiving power but the grinding plate is jammed.

This is commonly caused by:

  • Food debris buildup

  • Foreign objects such as utensils or bones

How to Reset a Garbage Disposal

Most disposals include a reset button located on the bottom of the unit. The video shows:

  • Where to find the reset button

  • When resetting is appropriate

  • What to do if the reset does not resolve the issue

What Is a Jam Buster and How Is It Used?

A jam buster, also called a hex key or Allen wrench, fits into the bottom of the disposal and allows you to manually rotate the grinding plate to clear jams.

The video demonstrates:

  • Where the tool is inserted

  • How to safely rotate the disposal

  • When to stop and seek professional help

How to Manually Unjam a Garbage Disposal

Manual unjamming may involve:

  • Turning off power to the disposal

  • Using a jam buster tool

  • Carefully removing visible objects causing the blockage

Hands should never be placed inside the disposal.

Troubleshooting

  • Disposal is silent → Check power and reset button

  • Disposal hums but does not spin → Likely jammed and may require manual rotation

  • Disposal resets repeatedly → May indicate a deeper mechanical issue
