Furnace shows 14, burner stops, may be associated with condensate issues

Safety: Condensate is mildly acidic. Wear gloves and eye protection when handling.

Steps:

• 1. Inspect condensate pipe: Follow the plastic condensate pipe from the boiler to the drain. Check for kinks, sags, or external blockages.
• 2. Check for freezing: In cold weather, external sections can freeze. Thaw gently with warm (not boiling) water and insulate the pipe.
• 3. Clean condensate trap: Place a container under the trap, remove it carefully, and flush with clean water. Remove any sludge or debris. Refit securely and check for leaks.
• 4. Verify slope: Ensure the pipe slopes continuously downward to the drain to avoid standing water.
