How to Fix / Troubleshooting
Safety: Turn off power before working near water and electrical components.
Steps:
- Locate leak source: Remove panels and observe where water is originating: trap, hoses, collector box, or heat exchanger.
- Tighten connections: Secure any loose hose clamps or push-fit connections on the condensate system.
- Clear blockage: Flush the condensate trap and drain line with warm water until flow is clear.
- Replace damaged parts: If the trap or hoses are cracked, replace them with Atlantic-approved condensate components.
Warning: If water appears to be leaking from the heat exchanger itself, shut down the furnace and call a professional.
