TROUBLESHOOTING (CONT)
Error Display (Indoor Unit)
When the indoor unit encounters a recognized error, the indicator light flashes in a corresponding series, the timer display may turn on or begin
flashing, and the error code displays. See Table 9 for the error codes and meanings.

For other codes
The display board may show a garbled code or a code undefined by the service manual. Ensure that this code is not a temperature reading.
Troubleshooting
Test the indoor unit using the remote controller. If the unit display is working however will not respond to the remote, the indoor PCB needs
replacing. If there is no display after pressing LED and the unit responds, the display board needs replacing.
Manufacturer reserves the right to change, at any time, specifications and designs without notice and without obligations.
