Safety: Turn off power before inspection.

1. Inspect condensate lines: Check for leaks or clogs in condensate hoses and trap. Repair as needed.
2. Humidifier check: If a bypass or powered humidifier is attached, inspect its water connections and drain for leaks.
3. Venting: Ensure vent pipes are properly sealed and sloped to prevent condensation from dripping back into the furnace.
4. Professional evaluation: Significant internal rust may indicate long-term leakage or heat exchanger issues and should be evaluated by a technician.
