I have a AQV12VBE that gives error E2 03 (not on the error code list in the manual) on the indoor unit, and 1 min time out communication (yellow blinking, red and green ON).
I tried re-entering the option code, from the service manual :
05E777-17722D
Which doesn't work (unit beeps but nothing else happens). Then I tried,
054777-17521D
and
054777-17421D
Found on this forum for the AQV12VBCN family. Both code are accepted but I keep getting the E2 03 error.
Anyone have any suggestion on how to fix the problem, before I start looking at the PCB ?
Thanks
