Troubleshooting and error codes
| PROBLEM | POSSIBLE CAUSES | RECOMMENDED SOLUTIONS |
|---|---|---|
| The Air Conditioner Will Not Start | The air conditioner is unplugged. | Make sure the power supply cord is plugged into a grounded 3 prong outlet. |
| The fuse is blown/circuit breaker is tripped. | Check the house fuse/circuit breaker box and replace the fuse or reset the breaker. | |
| Power failure | The unit will automatically restart when power is restored. There is a protective time delay (approximately 3 minutes) to prevent tripping of the compressor overload. The unit may not start normal cooling for 3 minutes after it is turned back on. | |
| The power cord reset button is tripped. | Press the reset button located on the power cord plug. If the reset button will not stay engaged, discontinue use of the air conditioner and contact a qualified service technician. | |
| The Air Conditioner Is Not Cooling Properly | Airflow is restricted. | Make sure there are no curtains, blinds, or furniture blocking the front of the air conditioner. |
| The temperature control is not set correctly. | Lower the set thermostat temperature. | |
| The air filter is dirty. | Clean the filter. See the "Air Conditioner Care" section. | |
| The room is too warm. | Allow time for the room to cool down after turning on the air conditioner. | |
| Cold air is escaping. | Close all open doors and/or windows where warm air may be entering. | |
| The Air Conditioner Is Freezing Up | The cooling coils are frozen. | See "The Air Conditioner Is Freezing Up" below. |
| Ice is blocking the airflow. | Turn 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 Working | Batteries are inserted incorrectly. | Check that the batteries are inserted in the correct direction. |
| Batteries are dead. | Replace the batteries and dispose of them in a responsible manner. | |
| Water Is Dripping From the Unit on the Outdoor Side | The 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 Room | The 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. See the "Installation Instructions" section. NOTE: Do not drill a hole into the bottom of the metal base pan; doing so will reduce cooling performance. |
| Water Collects in the Base Pan | Moisture 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. |
