Disposal runs but causes lights to flicker or dim significantly when starting.

Safety First: Electrical issues can be hazardous. Turn OFF power at the breaker before inspecting wiring. Consider consulting a licensed electrician.

• Step 1 – Check circuit loading: Identify what else is on the same circuit as the disposal. Ideally, the disposal should be on a dedicated 15–20 A circuit.
• Step 2 – Inspect connections: Check the breaker panel, wall switch, and disposal junction box for loose or burned connections. Tighten or replace as needed.
• Step 3 – Monitor operation: If flicker is minor and brief at startup, it may be normal. Severe or prolonged dimming suggests an electrical supply or motor problem.
• Step 4 – Evaluate motor: If the disposal struggles to start or hums before spinning up, the motor may be failing and drawing excessive current. Replace the unit if confirmed.
