4-4-44 Constant Rate Compressor Discharge Temperature Sensor Error (OPEN/SHORT)
1. Inspection Method
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
temperature 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 changing PCB.
Restart operation after connecting
the connector to PCB
Change this part as it is the fault of
the constant rate compressor discharge
temperature sensor itself.
