WHY IS MY GARBAGE DISPOSAL HUMMING / BUZZING?
A common problem is a humming sound when a garbage disposal is clogged or jammed by an object. The disposal is still receiving power. Still, unfortunately, it is unable to grind food. You can try to fix it but make sure you have turned the unit off first. Just call R&R Plumbing to fix this problem and any other issues you have with your garbage disposal.
