My garbage disposal is not working, it's humming and making an odd noise but won't come on..

Hi Caroline, On the bottom of disposal, there should be a hex wrench hole you can put an ellen wrench in and turn it. Sometimes the disposal will get a pit in it or some other harder item that can tie it up. Manually turning it can break it loose. Doing this works most of the time , if it spins freely, and still makes the humming noise. The disposal will need to be replaced…. Looking forward to hearing back from you and this helps!
