1. How to check
Is a discharge temperature sensor
connector for a fixed outdoor scroll compressor
dislocated from the PCB?
Does the resistance
valve greatly deviate from the
temperature table?
After separating the discharge temperature
sensor connector of the fixed outdoor scroll
compressor from the PCB, measure the
resistance value between both terminals.
Restart after replacing the PCB.
Restart after connecting
the connector to the PCB.
As it is due to a problem with the
