How to Fix / Troubleshooting

Safety First: Electrical issues can be hazardous. If unsure, consult a licensed electrician.

  • Step 1 – Note behavior: Observe whether lights dim only briefly at startup (common) or remain dim or flicker continuously (problematic).
  • Step 2 – Reduce shared load: Avoid running other high-load appliances on the same circuit while using the disposal.
  • Step 3 – Inspect motor performance: If the disposal struggles to start, hums, or trips breakers, the motor may be failing and drawing excessive current.
  • Step 4 – Consider dedicated circuit: For persistent dimming, have an electrician evaluate the circuit and possibly move the disposal to a dedicated line per local code.
