Discharge pressure sensor
When any of the following conditions is satisfied, a discharge pressure
sensor error is generated.
1. 30 seconds or more have elapsed since the outdoor unit power was turned
on and pressure sensor detected value 0.3V continued for 30 seconds
or more
2. 30 seconds or more have elapsed since the outdoor unit power was turned
on and pressure sensor detected value 5.0V was detected.
1. Discharge pressure sensor connector disconnection, open
2. Discharge pressure sensor defective
3. Main PCB defective
OK
Check Point 1 : Check the discharge pressure sensor connection state
Connector connection state check
Cable open check
Check Point 2 : Check the discharge pressure sensor
Sensor characteristics check
* For the characteristics of the discharge pressure sensor,
refer to the "Service Parts Information 20".
Main PCB (CN118:1-3) voltage value = 5V
Remove the thermistor from Main PCB, check the voltage.
