Symptoms
- Reset button clicks in normally
- Disposal hums or is silent even after reset
- No grinding motion despite power being restored
- Problem persists across multiple reset attempts
Likely causes
- CommonJam not fully cleared before resettingResetting restores power but doesn't remove an object still stuck against the flywheel.
- PossibleMotor damaged from the overload event that caused the original tripA severe jam or overheating episode can damage windings even after the jam is cleared.
- Less commonCapacitor or start winding failureThe motor may need power surging to start but fail to develop torque.
What to do
- Cut power again and use the hex wrench in the bottom hole to confirm the flywheel now spins completely freely by hand.
- Check thoroughly with a flashlight for any remaining debris, since even a small piece can prevent the motor from starting.
- Once confirmed completely clear, restore power and press reset again.
- Turn on cold water and switch the disposal on, listening closely for a hum versus complete silence.
- If it's silent, recheck power at the outlet and breaker.
- If it hums with a confirmed clear flywheel, the motor has likely failed internally and needs replacement rather than another reset.
Tools and parts
- 1/4-inch hex wrench
- Flashlight
When to call a pro
If the flywheel spins freely by hand but the motor won't turn it under power, the disposal needs replacing.
Safety
Use caution
Confirm the flywheel is completely free by hand before assuming a motor failure; a partial jam can still prevent starting even after a reset.
