Safety: Turn OFF power before working around water and electrical components.

  • Step 1 – Inspect drain pan: Remove the front cover and check for standing water in the pan.
  • Step 2 – Clear drain line: Use a wet/dry vacuum on the drain line outlet outside to remove clogs. Flush with water and a mild bleach solution if allowed.
  • Step 3 – Level the unit: Ensure the indoor unit is slightly tilted toward the drain outlet.
  • Step 4 – Check for cracks: Inspect the drain pan for cracks or separations. If damaged, the pan or entire indoor chassis may need replacement.
  • Step 5 – Consider drain pump: If a condensate pump is used, verify it runs and discharges water properly. Replace if failed.
