Bryant air conditioner causes lights to dim significantly when starting; occasional breaker trips on startup.

Safety first: Turn off power at the main panel and outdoor disconnect before inspecting wiring. High-voltage work should be done by qualified persons.

Steps:

• 1. Check breaker size: Verify that the breaker size matches the Bryant unit's nameplate MCA/MOP ratings. Do not upsize the breaker beyond manufacturer specs.
• 2. Inspect connections: With power off, check that lugs in the outdoor disconnect and at the condenser contactor are tight and free of corrosion.
• 3. Evaluate start components: Many Bryant units use a dual run capacitor and sometimes a start assist kit. A technician can test and replace these to reduce inrush current.
• 4. Electrical service check: If dimming is severe, have an electrician evaluate the home's service capacity and connections.
