Did the connector for the
outdoor suction sensor break away
from the PCB?
Did the resistance value
significantly stray from the following
temperature table?
Separate the connector of the
outdoor suction sensor from the PCB and measure
the resistance value between the 2 terminals.
Restart operation after changing PCB.
Restart operation after connecting
the connector to PCB.
Change this part as it is the fault of the
