Possible Causes
Sheared drive connection inside motor, Broken coupling between rotor and plate, Internal mechanical failure
How to Fix / Troubleshooting
Safety First: Turn OFF power immediately. Do not continue to run a disposal with a free-spinning motor and stationary plate.
Step-by-step:
- 1. Confirm symptom: Look into the KitchenAid disposal while it is briefly turned on (use caution). If you hear the motor but see no movement, the drive is compromised.
- 2. Manual test: With power OFF, rotate the plate using the bottom hex socket. If it spins freely but does not engage the motor, the coupling is broken.
- 3. Do not disassemble motor: Internal couplings are not user-serviceable.
- 4. Remove food: Clear as much food as possible from the chamber to prevent odor while awaiting replacement.
- 5. Plan replacement: Select a compatible KitchenAid disposal and schedule installation.
When to call a technician: Internal mechanical failures require full unit replacement.
