Tweeny Sheared Coupling / Disconnected Rotor

Garbage disposal motor runs but grinding plate does not spin (free-spinning noise)

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

Broken internal drive coupling, Stripped motor shaft connection, Manufacturing defect after severe jam

Safety First: Turn OFF and disconnect power before inspection.

Step 1 – Check from top: Look into the chamber while briefly turning the unit ON (use extreme caution and only for a second). If you hear the motor but the plate does not move, the coupling is likely failed.
Step 2 – Manual rotation: With power OFF, rotate the plate with a wooden tool. If it spins freely without motor resistance, the internal connection is broken.

Internal couplings on Tweeny disposals are not user-replaceable. Replace the entire unit.
