Yes
Did the connector for the
outdoor digital compressor discharge temperature
sensor break away from the PCB?
Did the resistance value
significantly stray from the following
temperature table?
Separate the connector for the outdoor unit
discharge temperature 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 discharge temperature sensor itself.
