Moen garbage disposal causes dimming lights or flicker when starting

Safety first: If lights flicker significantly or other devices reset, consult an electrician. Do not open electrical panels unless qualified.

• Check circuit loading:
  • Identify what else is on the same circuit as the disposal.
  • Move high-draw appliances to other circuits if possible.
• Inspect connections (qualified person):
  • Have an electrician check for loose connections at the breaker, junction boxes, and outlet.
• Consider dedicated circuit:
  • For higher horsepower Moen disposals (e.g., Host, Chef series), a dedicated 15–20A circuit is recommended.
• Replace aging unit:
  • If the disposal is old and drawing excessive current, replacing it may reduce inrush and flicker.
