Why Is My Garbage Disposal Humming But Not Working?

Why Is My Garbage Disposal Humming?

When your garbage disposal makes a humming noise but doesn’t grind, it usually means the unit is getting power but the blades aren’t spinning. Most often, this is due to:

• Jammed impellers or flywheel

• Foreign objects stuck inside

• Overheating or a tripped reset button

• Motor failure

If the humming is constant and the unit won’t turn, continuing to use it could burn out the motor. That’s why it’s important to act quickly.

What to Do If Your Garbage Disposal Is Humming

First, turn off the disposal and unplug it for safety. Then:

1. Use a flashlight to check for blockages like bones, silverware, or food debris.

2. Try turning the flywheel manually with a hex wrench using the slot underneath the unit.

3. Press the reset button located on the bottom if it’s overheated.

If that doesn’t solve the issue, it might be time to reach out to a licensed plumber for professional help. We specialize in garbage disposal services throughout the East Bay, including routine maintenance and complete replacements.

Common Causes of Garbage Disposal Jams

Jams are typically caused by putting the wrong items down the disposal. As we covered in our post about why you shouldn’t put food in the garbage disposal, starchy foods like pasta, fibrous peels like banana or potato skins, and even coffee grounds can cause clogs and jams. Our garbage disposal repair services help clear these problems quickly and safely.

FAQs

How do you fix a garbage disposal that is humming?

If your garbage disposal is humming but not grinding, it likely means the unit is jammed or the motor is stuck. First, turn off the power to the disposal. Then use a hex key in the bottom slot of the unit to manually turn the flywheel and free any blockages. If that doesn’t work, inspect for food debris or foreign objects like silverware that may be jamming the impellers.

How do I get my garbage disposal to spin again?

When your garbage disposal won’t spin, it’s often due to something caught in the impeller blades or a tripped internal breaker. Use a flashlight to check for clogs, remove any visible debris with tongs or pliers, then insert a hex wrench underneath the disposal to manually rotate the flywheel. If it starts moving freely, you can try turning the power back on to test it.

How to reset a garbage disposal?

Most garbage disposals have a red reset button on the bottom of the unit. If the motor has overheated or tripped due to a jam, turn off the unit and press this button. Wait a few minutes, then restore power and run cold water while testing the unit. If the reset doesn’t solve the issue, you may need professional garbage disposal repair.

How to unjam a garbage disposal?

To unjam a garbage disposal, first cut power to the unit for safety. Insert a ¼-inch Allen wrench into the hex hole on the bottom and turn it back and forth to loosen the flywheel. This action helps dislodge trapped debris inside the grinding chamber. Always avoid putting your hands inside the disposal and never force it on while jammed.

How do I know if my garbage disposal motor is burned out?

Signs that your garbage disposal motor is burned out include humming without grinding, frequent tripping of the reset button, or complete unresponsiveness even after resetting. If you’ve ruled out jams and electrical issues, a burned-out motor often requires full garbage disposal replacement.
