What Does Error PA Mean?
The Daikin air conditioner PA error indicates that the unit is in a refrigerant automatic charging operation during its test run, rather than signaling a malfunction. This code is typically displayed on the remote or controller during startup, and does not affect the unit's normal cooling or heating functions. While in this mode, the air conditioner may not operate normally, but it is not indicative of a fault. Ensure that the PA code is only present during commissioning or initial tests, and consult your unit's documentation for specific instructions.
Common Symptoms:
- PA displayed on remote or controller during test operation/startup
- Air conditioner may not start normal cooling/heating while in this mode
- Not accompanied by fault-condition symptoms like loud abnormal noise or system shutdown
Possible Causes
- Refrigerant automatic charge/test operation indicator (medium)

- Check if the PA code appears only during initial test run or commissioning of the unit
- Refer to your specific unit installation and startup instructions for this code context
- Do not perform system resets or power interruptions unless instructed in the installation manual
Technician Only Follow commissioning or servicing procedures
- Verify if PA corresponds to a planned refrigerant auto-charge/test run per installation procedure
- Use official service documentation specific to the model to interpret PA
- If the code persists outside of expected test phase, perform standard diagnostic checks with proper tools
- PA persists outside of startup/test mode and the unit does not transition to normal operation
- Other abnormal symptoms (noise, loss of cooling/heating) accompany the PA display
