High Pressure Sensor Error
1. Error Detection Method
It is judged an error based on the criteria listed below.
- Cooling: Status of lower 5°C saturated temperature under the detect pressure compared to the outdoor heat exchanger liquid temperature (C1 temp.) was continuosly detected for 30 minutes.
- Heating: Status of lower 5°C saturated temperature under the detect pressure compared to the highest E1 temperature in the indoor unit was continuously detected for 30 minutes.
- Open circuit or Short circuit
2. Error Diagnosis
1 Sensor |
1-1 |
Sensor Sensor connector is connected to control PC board properly. |
Yes |
1-2 |
No
|
Reconnect and check |
1-2 |
Is sensor resistance value in normal? Disconnect the connector and measure the resistance value between each wire of sensor. Correct reference values: between 1-2: 8.5 k ohm, 1-3: 1.0 k ohm, 2-3: 8.5k ohm |
Yes |
2-1 |
No |
Replace sensor |
2 Operating status |
2-1 |
Replace PC board because of outdoor control PC board failure. |
Yes |
Correct |
No |
2-2 |
2-2 |
Tends to have insufficient refrigerant charge in the system. |
Yes |
Adjust the amount of refrigerant |
No |
2-2 |
2-3 |
Are the tubes clogged? |
Yes |
Avoid clogging |
No |
3-1 |
3 Control PC board |
3-1 |
The difference between the value of actual high pressure and that of detect pressure will roughly indicate as shown below.

- When measuring the value of actual high pressure, connect the measuring gauge to the high pressure outlet port and measure it.
- The detect pressure value is the pressure value indicated by the monitoring software display.
|
Yes |
Replace sensor |
No |
Replace control PC board |
