How to Fix / Troubleshooting

Safety first: Electrical issues should be evaluated carefully; consider using a qualified electrician.

  • Step 1 – Check circuit sharing: Identify if the disposal shares a circuit with lighting. If so, consider moving it to a dedicated circuit.
  • Step 2 – Inspect panel connections: Have an electrician check for loose neutral or live connections at the breaker and neutral bar.
  • Step 3 – Observe start behavior: If the disposal struggles to start or hums before running, the motor may be failing and drawing excess current.
  • Step 4 – Replace unit if motor is suspect: A failing motor should be replaced to prevent nuisance tripping and potential overheating.
