Water leaking around the base of a high-efficiency Frigidaire furnace.

Safety: Turn off the power before working near water and electrical components.

• 1. Locate condensate system: Identify the condensate trap and drain hoses connected to the furnace and its vent.
• 2. Clear trap: Remove the trap (note its orientation), flush it with warm water, and clear any debris or slime. Reinstall it correctly.
• 3. Secure hoses: Ensure all hoses are firmly attached and routed to a proper drain. Replace any brittle or cracked tubing.
• 4. Check vent slope: Verify that PVC vent pipes slope back toward the furnace or drain as specified by Frigidaire to allow condensate to drain.
• 5. Professional repair: If the secondary heat exchanger or internal drain pan is cracked, a technician will need to replace the affected components.
