| Code | Common Meaning | Likely Resolution |
|---|---|---|
| P1 | Intake Air Sensor Error | Clean the filter and sensor; check for loose wiring. |
| P6 | Freeze/Overheat Safeguard | Ensure outdoor coils are clear of debris; check airflow. |
| E0 | Communication Error | Inspect wiring between the indoor and outdoor units. |
| UP | Compressor Overcurrent | Electrical fault; often requires professional technician inspection. |
| PA | Forced Shutdown | System protect mode; usually due to extreme heat or overload. |
Reset Tip: You can often clear "soft" errors by turning off the unit and disconnecting power at the breaker for at least 5 minutes. Globalinsightservices
