Prevention And Maintenance Tips

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.

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.

Thank you! The Allen wrench freed up the jam. I was worried that I may need to buy a new garbage disposal.
It worked ! The allen wrench and the hot water fixed the problem. Filled sink with hot water twice,then took allen wrench and turned to the right and the magic happen. The garbage disposal worked. thank you for saving me the money and time….
My garbage disposal started humming. Got on here and read about using the wrench at the bottom of the unit. Worked like a charm! Thanks for the tip :)
Happy Thanksgiving!! have an older GE Disposall (1995/1996) in my mobile home that has started humming. Broom handle / wooden spoon method hasn’t worked. Re-set button, same same. There is no place for an allen wrench on the bottom, but there is a silver metal plate over the bottom center, similar to electric access on a water heater. Could that be hiding the Allen wrench hole?? Thanks for any help. Hope you have a great Holiday Season !! Ray
I used a 1/4 inch allen wrench…it fixed the problem. I, too, was getting ready to buy a new disposal…..thought I’d search the internet for troubleshooting ideas….this fixed it. Now my wife thinks I’m a genius….thanks.
Thanks! I had tried all the steps, except the allen wrench turning from the bottom. I hadn’t even seen the wrenchette? before, but sure enough there it was on the floor of the cabinet under the sink. A couple of full rotations in either direction until it turned relatively easy all the way around and I was good to go.
The Allen wrench fixed it! Thank you. I didn’t even know that hole was there until I went looking for it.
Thanks! Fixed it in 2 minutes with the allen wrench. Saved me $100. I was getting ready to buy a new garbage disposal.
How do you determine if there is a blockage in the bottom of the disposal?
The turning of the blades with the allen wrench fixed it right away. Thanks!
