For other errors:
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 unit using the remote control. If the unit does not respond to the remote, the indoor PCB requires replacement.
If the unit responds, the display board requires replacement.
