* Fault Symptom:
The display board shows a garbled code or a code that is not an error code found
in the service manual nor a temperature reading.
Trouble shooting:
Use the remote controller. If the unit does not respond to the remote, the indoor PCB needs to be
replaced; if the unit does respond, then the display board needs to be replaced.
