Whole-home Carrier humidifier leaks water onto the furnace or floor.

Safety first: Turn off furnace power and shut off the humidifier water supply. Avoid water contact with electrical components.

Steps:

• 1. Inspect drain line: Disconnect the drain hose from the humidifier and clear any blockages. Flush with hot water or use a wet/dry vacuum.
• 2. Check drain pan: Ensure the internal drain pan is properly seated and not cracked.
• 3. Verify slope: The drain hose should slope continuously downward to the floor drain. Adjust routing if necessary.
• 4. Restore water and test: Turn water back on and observe for leaks while the humidifier runs.
