How to Fix a Garbage Disposal That Hums (4 Tips)
A garbage disposal is a great tool, but it can be frightening when it starts humming, especially if it also stops working. If you have been having problems with your garbage disposal, keep reading as we list several tips to help you get it working properly. We cover doing diagnostics, cleaning, unjamming, and resetting your machine and discuss items that you shouldn’t put in the disposal system.
The 4 Tips on How to Fix a Garbage Disposal That Hums
1. See If There Is a Jam
A humming garbage disposal is more common than you might think, and one of the most common causes is a piece of food that jams the blade and prevents it from moving. The struggling motor produces the loud humming sound that you hear, so you should shut it down quickly to prevent damage. Freeing the jam will help it run normally again.
2. Manually Rotate the Grinding Plate
If you are unable to see a jam, but the hum is still occurring, you will need to manually rotate the grinding plate. In many cases, grease and grime can build up on the blades, preventing them from turning correctly, so manually rotating the blades will help you clean them off.

3. Reset the System
If your garbage disposal is still not working, one more option you have is to reset the system. Most garbage disposal systems have a reset button. Find and push it. Give the garbage disposal another try to see if the reset helped remove the hum.
4. Call a Professional
If these tips and tricks didn’t work to eliminate the hum, there is a good chance that an internal problem is causing it and not a food jam or grease buildup, so we recommend calling a qualified technician to have a look. They will be able to diagnose the problem and fix it without voiding the warranty.
How Can I Keep My Garbage Disposal System Running Properly?
We recommend that you avoid putting these foods down the drain in order to prevent your garbage disposal system from clogging up.
In most cases, a loud humming sound coming from the garbage disposal is the result of food clogging up the blades and preventing them from spinning. Shutting off the machine, unplugging it, and using a flashlight to find the clog and a pair of long bent nose pliers to remove it will get your system running like new in just a few minutes. If the noise is due to a buildup of grease and grime preventing the blades from spinning freely, manually rotating the ground plate can help you clean it up so it works correctly. In some cases, the system might overheat, and a press of the reset button will get it working again, but if all else fails, you will need to call a professional to ensure that there is no internal damage preventing the machine from working.
