Safety: Unplug the unit. Wear gloves and a mask if sensitive to mold.

Steps to remove odor:

  • Clean coils: Remove the front panel and gently clean the evaporator coil with a coil cleaner approved for aluminum fins. Rinse lightly if the product requires it, avoiding electrical parts.

  • Flush drain hose: If using continuous drain, disconnect and flush the hose with a bleach solution (then rinse) to kill mold.
  • Run on fan-only: After reassembly, run the unit on fan-only mode for 30 minutes to help dry internal surfaces.
