Did the connector for
the outdoor constant rate compressor discharge
temperature sensor break away
from the PCB?
Did the resistance value
significantly stray from the following
temperatu
re table?
Separate the connector for the outdoor constant
rate compressor discharge temperature sensor from
the PCB, and measure the resistance value between
the 2 terminals.
Restart operation after chang
ing PCB.
Restart operation after connecting
