Why Does My Garbage Disposal Hum?
Jammed or Stuck Objects: Foreign objects such as utensils, bones, or fibrous food waste can become lodged in the disposal, causing it to hum.

Worn or Damaged Motor: If the motor is damaged or worn out, it may struggle to operate and create a humming noise.

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.
- Perform periodic maintenance checks to ensure the disposal is functioning correctly.

Nothing is jamming the blades, I’ve reset the button and turned the breaker socket several times but it still only hums when I turn it on. Any suggestions?
Thank you so much! The Allen wrench worked in a second and you saved me a lot of stress! Very straightforward.
Thanks for this post! It left me feeling very proud to have fixed my own disposal. It also prevented a seriously gross sink situation! :) Thank you thank you thank you!
The hex wrench trick would work briefly but the disposal would jam again almost immediately. We unplugged it and felt for whatever it was jamming the disposal and tried using a flashlight but just could not find it.
What ended up working for us was plugging it back in again, filling the sink with hot water and Dawn, and my husband started turning the hex wrench back and forth while I took the stopper out of the drain and let the hot water and soap pour down the drain.
It was a solid 2-3 minutes of turning when the water suddenly started draining normally, so he turned it a little more and then tried the disposal and it worked!
We then did the ice cube trick you mentioned above just to make sure whatever was jamming it came out.
This was really helpful, thanks!
This was super super helpful!
Thank you so much for this! I knew about the red button but didn’t know about the hex bolt spot. I thought my Sunday was ruined with the unexpected death of an appliance, but my trusty bicycle allen wrench set (and your instructions) saved the day.
Dreaded the idea of having to remove the disposal after a ceramic spoon accidentally fell inside the unit.
After inspecting and ensuring the disposal was clear of any major shards, I turn on the unit to find it still humming.
This google search saved me the aggravation of removing the unit completely.
A simple twist of the Allen screw on the bottom of the disposal did the trick.
I had forgotten about that tip.
Thanks for this helpful post!
Badger 1/3 hp disposal, getting power but won’t spin. Cleaned out unit and found some sting got wound up in the disposal. Cleared and still wouldn’t spin but has power. Tried reset, but no difference. Used hex wrench and unit is spinning free and clear. Powered up, still won’t spin but has power. Figured some of string may have worked its way under fly wheel so I pulled whole unit out, cleaned thoroughly, took main motor completely off, got under fly wheel and yes, there was a bit of string. Cut out, flywheel spun free and clear. Put whole unit back together, reinstalled, fired it up and yes it still has power but still doesn’t want to spin. What could possibly be causing this as I’ve troubleshooted everything I can think of.
Adam,
If your garbage disposal is vibrating excessively, make sure the mount is snug and not damaged. If it is bent the disposal may move and vibrate. Adjust the disposal correctly and then tighten the mounting screws extra tight. If it continues to vibrate, take the disposal out and visually check all parts to see if something is damaged, bent, etc…

I have an Insinkerator evolution excel 2 garbage disposal. It has been vibrating more than it should. I removed the unit from the mount and loosened mounting screws. Now the vibration is better but the mounting unit moves. I can see the flange turn when unit fires up. When i adjusted it to make the unit snug so it wouldn’t move, the vibration returned. Unit spins freely and there is no debris in the unit.
