4-4-55 Suction-2 Temperature Sensor Error (OPEN/SHORT)
1. Inspection Method
Yes
Did the connector for the
Suction-2 sensor break away from the PCB?
Did the resistance value
significantly stray from the following
temperature table?
Separate the connector of the Suction-2 sensor
from the PCB, and measure the resistance value
between the two terminals.
Restart operation after changing PCB
Restart operation after connecting the
connector to PCB
Change this part as it is the fault of the
outdoor Suction-2 sensor itself.
