Reginox Sheared Coupling / Disconnected Rotor

Garbage disposal motor runs, but the grinding plate does not move; no grinding occurs.

Safety Warning

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 between motor and grinding plate, Stripped rotor shaft, Severe jam causing mechanical failure, Manufacturing defect in coupling

How to Fix / Troubleshooting

Safety first: Turn off power at the breaker.

Check shaft rotation: Use the bottom hex socket to rotate the shaft. If the shaft turns but the impeller plate inside the chamber does not move, the internal coupling is broken.
Listen for free-spinning motor: When briefly powered (with water and no load), a free-spinning motor with no grinding noise supports a coupling failure.
Non-serviceable part: Internal couplings are not typically replaceable on Reginox disposals.
Replace unit: Remove and replace the entire disposal to restore proper operation.
