Self-Diagnosis Process
When the error indication E
is displayed, follow these steps to perform the self-diagnosis:
- Stop the air conditioner operation.
- Press the master control button and the fan control button simultaneously for 2 seconds or more to start the test run.
- Press the start/stop button to stop the test run.
Remote Controller Display for Self-Diagnosis:
- Stop the air conditioner operation.
- Press the set temperature buttons simultaneously for 5 seconds or more to start the self-diagnosis.
- Refer to the error codes below for detailed information:
- Error Code = 00: Communication error (indoor unit to remote controller)
- Error Code = 01: Communication error (indoor unit to outdoor unit)
- Error Code = 02: Room temperature sensor open
- Error Code = 03: Room temperature sensor short-circuited

Press the set temperature buttons simultaneously for 5 seconds or more to stop the self-diagnosis.
Outdoor Unit LED Error Codes
When the outdoor temperature drops, the outdoor unit’s fans may switch to low speed. The LED lamps indicate the error contents:
- Red Light Operation = Off, Green Light Timer = 2 Flashes: Reverse Comms Fail at Startup
- Red Light Operation = Off, Green Light Timer = 3 Flashes: Reverse Comms Fail In Use
- Red Light Operation = Off, Green Light Timer = 4 Flashes: Forward Comms Fail at Startup
- Red Light Operation = Off, Green Light Timer = 5 Flashes: Forward Comms Fail In Use
- Red Light Operation = Off, Green Light Timer = 8 Flashes: Wired Remote Control Failure
- Red Light Operation = 2 Flashes, Green Light Timer = 2 Flashes: Indoor Air Sensor Fail
- Red Light Operation = 3 Flashes, Green Light Timer = 2 Flashes OD: Discharge Sensor Fail
