Whirlpool garbage disposal causes lights to dim or flicker when starting.

Safety first: Turn off power before inspecting electrical panels or junction boxes.

• Check circuit configuration: Ideally, the Whirlpool disposal should be on a dedicated circuit separate from lighting. Consult an electrician if it shares a circuit.
• Inspect connections: Have a qualified person check for loose neutrals or hots in the panel and junction boxes.
• Monitor performance: If the disposal starts quickly and runs normally, minor dimming may be acceptable. If dimming is severe or prolonged, the motor may be failing or the circuit undersized.
• Consider replacement: An older motor drawing excessive current may require replacement of the disposal.
