Musty or moldy odor when the unit starts

Safety: Unplug the unit before cleaning. Wear gloves and eye protection when using cleaners.

Steps:

• Clean filter: Wash the air filter with soap and water and let it dry.
• Clean evaporator coil: Remove the front cover and apply a foaming, no-rinse coil cleaner approved for aluminum fins. Allow it to work per instructions.
• Clean drain pan: Wipe out the condensate pan with a mild bleach solution (1:10 bleach to water) to kill mold and mildew. Rinse thoroughly.
• Clear drain: Ensure the drain holes or tube are open so water does not stagnate.
• Run fan-only: After cleaning, run the unit in FAN ONLY mode for 30–60 minutes to help dry the coil and pan.
