How to Fix / Troubleshooting

Safety First: Turn OFF the breaker before removing any covers. Buzzing can indicate arcing, which is a fire hazard.

  • Step 1 – Inspect wall switch: Remove the switch cover and check for loose screws or burned insulation. Replace the switch if damaged.
  • Step 2 – Check outlet (if corded): Inspect the receptacle for heat discoloration or looseness. Replace if worn.
  • Step 3 – Tighten connections: Ensure all wire connections in the switch box and under-sink junction box are tight and properly capped.
  • Step 4 – Test disposal: After reassembling, restore power and test. If buzzing persists from electrical components, consult an electrician.
