Normally, when you hear your garbage disposal humming but not spinning and grinding as it should – the problem is usually that something has fallen into the unit and is now stuck and is preventing the blades from spinning.

How Do I Fix A Garbage Disposal That Just Hums?

Steps To Fixing That Humming Noise Coming From Your Garbage Disposal

Safety first – so unplug your garbage disposal.

Use a flashlight to look down your sink’s drain to see if you can find the object that is stuck in the blades of the disposal.

If you can see it then try to remove it.

If you are able to remove the object then plug the power back for the garbage disposal and hopefully, that item that you removed was the culprit and you will not hear that humming noise any longer.

If you are unable to remove the object we recommend that you contact a professional plumber to fix the issue.

How Do You Fix A Garbage Disposal That Will Not Spin?

Make sure the garbage disposal is still unplugged.

There should be an Allen wrench attached to the disposal – if not you will have to find one in your toolbox that fix the breaker socket on the disposal unit.

The breaker socket is normally found at the bottom of the unit.

With the Allen wrench, turn the socket back and forth a few times.

Plug the power back for the garbage disposal and test to see if the humming noise is gone.

If either of these procedures do not work for you, then we highly recommend that you contact a professional plumber to help fix the problem.
