Unpleasant musty or moldy smell from indoor unit when it starts.

Safety first: Turn OFF power before cleaning. Use only non‑corrosive coil cleaners approved for aluminum coils.

• Step 1 – Clean filters: Wash filters with mild detergent and dry completely.
• Step 2 – Clean evaporator coil: Remove the front panel and apply a no‑rinse foaming coil cleaner to the evaporator fins following product instructions.
• Step 3 – Clean drain pan: Wipe the drain pan with a cloth and a mixture of water and mild disinfectant to remove slime and odor.
• Step 4 – Use self‑clean function (if available): Many Gree units have a self‑clean or X‑FAN mode that dries the coil after use. Enable this feature to reduce future odors.
• Step 5 – Persistent odor: If smells persist, professional deep cleaning of the indoor unit may be required.
