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)
