When the error code 'PA' appears you can do the following to fix the problem:
- Check whether the condenser of the outdoor unit is dirty. This should be kept clean so it will not course any problems.
- Check whether the sensor and wire are normal.
- Make sure the unit isn't running in a bad condition.
