Tweeny Bearing or Shaft Bushing Wear

Garbage disposal emits a high-pitched squeal when starting or stopping

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Dry or worn motor bearings, Misaligned rotor, Debris caught near shaft seal

Safety First: Turn OFF and disconnect power before inspection.

Step 1 – Check for jams: Ensure no foreign objects are rubbing against the grinding plate.
Step 2 – Listen closely: If the squeal comes from the motor body rather than the chamber, bearings are likely worn.

Motor bearing issues are not serviceable on most Tweeny disposals. Plan to replace the unit.
