1. Cause of problem
Yes
Is the COND OUT
sensor connector (CN43) connected
to PCB?
Did the resistance
value significantly stray from the following
temperature table?
After separating the outdoor Cond Out sensor
connector from the PCB, measure the
resistance value between the two terminals.
Restart operation after replace the PCB.
Restart operation after connecting
