Project Source Loose Components / Internal Wear

Garbage disposal runs but is unusually loud compared to normal operation

Possible Causes

Loose mounting assembly, Worn motor bearings, Loose or broken impeller, Thin stainless sink amplifying vibration without support

How to Fix / Troubleshooting

Safety first: Disconnect power before tightening any hardware.

  • Check for foreign objects: Inspect and clear the grinding chamber of any debris.
  • Tighten mounting ring: Under the sink, tighten the three mounting screws on the Project Source mounting assembly and ensure the unit is fully locked into place.
  • Add sink support: If the sink is thin stainless, consider adding sound-dampening pads or bracing to reduce resonance.

If the noise is a harsh mechanical roar or rattle that persists after these steps, the internal bearings or impellers may be worn. Replacement of the disposal is typically more economical than internal repair.
