Excessive noise may be caused by vibration as outlined in the previous section "Garbage Disposal: Excessive Vibration" or by a hard, non-food object caught in the grinding hopper. This foreign object can be a piece of silverware, bottle cap, glass, etc.
- Turn off power to the disposal at the electrical service panel.
- Reach into the grinding hopper and feel about the flywheel and impellers for any hard foreign object.
- Also check the edge between the flywheel and the grinding chamber wall.
- Remove the object.
