Problem: Garbage Disposal Vibrating

If a garbage disposal is filled with food garbage it will vibrate under use. That is normal.

But if it vibrates when you turn it on and it is empty, you have a problem either with a broken impeller creating an unbalanced flywheel or the mounting bolts are too tight.

Checking for a Broken Impeller

Checking for a Excessive Mounting Bracket Tightness
There is a resilient rubber pad in the mounting assembly that is a vibration absorbing interface between upper mounting ring and the sink. If the bolts are too tight the rubber gasket will not absorb enough vibration.

Excessive noise may be caused a hard, non-food object caught in the grinding hopper. Things can fall into the sink. This foreign object can be a piece of silverware, bottle cap, glass, medicine dropper etc.

OK, the solution to this one is either a quick fix or a total replacement. The problem is caused by either:

Stuck Flywheel
In most cases a humming noise will be caused by a stuck flywheel. Let’s start with the easy possible problem, a stuck flywheel. Please see our article on a stuck flywheel.

Seized Motor Bearing
