Possible Causes

Weak or failing overload protector, Internal short causing repeated overcurrent, Motor drawing excessive current even under light load, Defective internal wiring or control in Moen unit

How to Fix / Troubleshooting

Safety first: Unplug the disposal or turn off the breaker before inspection.

  • Check for mechanical issues:
    • Ensure the jam plate spins freely using a jam-buster wrench.
    • Remove any obstructions from the grind chamber.
  • Observe operation:
    • Restore power, run water, and turn on the disposal.
    • If it runs briefly then trips the reset under no load, the overload protector or motor is failing.
  • Do not bypass safety devices:
    • Never attempt to bypass the reset/overload; this is a fire hazard.
  • Replace the unit:
    • Because the overload and internal wiring are not serviceable, replace the Moen disposal.
