Why Does My Garbage Disposal Hum?

Prevention And Maintenance Tips
Run Cold Water: Always run cold water while using the garbage disposal to help flush waste down the drain.
Avoid Fibrous Foods: Keep fibrous foods like celery, corn husks, and onion skins out of the disposal, as they can cause jams.
No Grease or Oil: Never pour grease or oil down the disposal as it can solidify and cause clogs.
Dispose of Bones Properly: Do not put bones in the garbage disposal, as they can break the blades or cause jams.
Clean Regularly: Clean your garbage disposal regularly by grinding ice cubes and lemon peels to keep it fresh and free of debris.
If you’ve tried the DIY methods and your garbage disposal is still humming, it might be time to call a professional plumber. They can diagnose and fix garbage disposal issues, such as a damaged motor, that may be causing the problem.
Garbage Disposal FAQs
1. What causes a garbage disposal to hum but not grind?
A humming garbage disposal usually indicates a jam or a stuck impeller. The motor is still running, but the grinding mechanism is unable to move due to a foreign object or built-up food debris. The humming sound is a result of the motor trying to turn the impeller but being unable to do so.
2. Is it safe to use a garbage disposal that’s humming?
No, it is not safe to use a humming garbage disposal. The humming indicates that the disposal is jammed, and continued use may lead to motor burnout, which can cause irreversible damage. Turn off the power to the disposal immediately and address the issue before attempting to use it again.
3. How can I fix a garbage disposal that’s humming but not working?
To fix a humming garbage disposal, follow these steps:
- Turn off the power and unplug the disposal.
- Inspect the grinding chamber for visible obstructions.
- Use a plunger or Allen wrench to free the impeller.
- Press the reset button on the bottom of the unit.
- Test the disposal to ensure it’s working properly.
If these steps don’t resolve the problem, consult a professional plumber.
4. Can a humming garbage disposal be a sign of a bigger problem?
While a humming garbage disposal is often a sign of a jam or stuck impeller, it may also indicate a more serious issue, such as a failing motor or damaged internal components. If you have tried the steps mentioned above and the disposal is still humming, it’s best to call a professional plumber to diagnose and fix the issue.
5. How can I prevent my garbage disposal from humming in the future?
To prevent your garbage disposal from humming, follow these tips:
- Run cold water before, during, and after using the disposal.
- Avoid putting fibrous or hard materials into the disposal.
- Cut large food items into smaller pieces before disposing of them.
- Regularly clean your garbage disposal with a mixture of baking soda and vinegar.

Thank you so much the first tip worked.
This totally worked. THANK YOU!!!! A couple of back and forth movements with 1/4 inch allen wrench!
D. Sutton,
Have you made sure there is nothing inside the disposer jamming it? Unplug the disposer and feel down inside it to be sure there is nothing jamming it. Then try the allen wrench at bottom to see if it will turn freely. If no jam and the disposer will not turn, try tapping the side of the disposer with a small hammer while it is running and humming. Sometimes a small jolt to it will get it working as the motor could be jammed and a small jolt will get it back spinning. If not then a replacement may be necessary.

The explanation was clear and precise. I did find the Allen wrench that came with my disposal and had no clue that that is what it is for. Thanks.
I have tried to use the jam buster but I can’t turn the wrench in spite of considerable force.
Any helpful ideas before I have to call a plumber?
Jon,
If the disposal turns freely with the hex wrench and it still hums, the motor may be bad or fried as you stated. It may have overheated and needs time to cool but usually will not hum if that is the case. Give it a few hours and try again, if it still hums and spins freely then remove and replace after doing some further troubleshooting.

When I turned on the garbage disposal this morning it made a humming sound. It has done this before and I got it unstuck with the hex wrench. This time the hex wrench turns the unit freely but it still only hums when I turn it on. The reset button is okay. Hmmmm…..fried?
Joan,
The disposal was jammed so you used the wrench on the bottom to get it to spin again, correct? Was there any type of rattling before this? You may have something that has fallen into the disposer such as a small metal object or similar. Unplug disposal and check with flashlight in the disposal. See if there is anything in there that should not be. If nothing visual is causing the rattle, you may have loose chopper or motor. Check that nothing is in there rattling first… If still rattles, let us know what make and model your disposer is and we can assist further.

I loosened the disposal by using the Wrenchette. When I turned it back on, it made a noise and the blade inside the disposer seems to be extremely loose and rattles. Can I tighten it? Or what should I do?
Thanks…gotta love google. How did anything ever get done before?!
I searched garbage disposal troubleshooting; saw “not humming” and voila…all taken care of!
