Does anybody know how to fix a garbage disposal? It's making a very low wurring sound even after I tried resetting it. Please advise. Thanks.

Can I assume it doesn't work? Is this sound always on or just went you turn it on?

Maybe something is jambed in it. UNPLUG IT! Then use a flashlight and look down inside.
And if there is something wrong with it(example.. motor blown, bearings shot, etc), its probably cheaper to just get a new one than try to fix it

If your blades are spinning and you do not see an obvious item try dumping a container of ice cubes with water while its running. If it just humms and doesn't spin let us know that.
