(H1 and SE is not error code, H1 is the indicator of defrosting during heating, SE is the indicator of power save function.)

Before calling for service, try the suggestions below to see whether you can solve your problem without outside help.

The Air Conditioner Will Not StartThe air conditioner is unplugged. Make sure the power supply cord is plugged into a grounded 3 prong outlet.
The Air Conditioner Is Not Cooling ProperlyAirflow is restricted. Make sure there are no curtains, blinds, or furniture blocking the front of the air conditioner.
The Air Conditioner Is Freezing UpTurn off the unit and allow it to thaw until the ice has melted, then operate on a higher fan speed. If this continues to occur, contact customer service for additional help.
The Remote Control Is Not WorkingBatteries are inserted incorrectly. Check that the batteries are inserted in the correct direction.
Water Is Dripping From the Unit on the Outdoor SideThe weather is hot and humid. This is normal during periods of high humidity. NOTE: Do not drill a hole into the bottom of the metal base pan; doing so will reduce cooling performance.
Water Is Dripping Inside the RoomThe air conditioner is not properly leveled. The air conditioner should slope slightly downward toward the outside. Level the air conditioner to provide a downward slope toward the outside to ensure proper drainage.
Water Collects in the Base PanMoisture removed from the air is collecting in the base pan. This is normal. Water that collects in the base pan will evaporate to the outside air. This helps with the unit's cooling process.

NOTE: Do not drill a hole into the bottom of the metal base pan; doing so will reduce cooling performance.
