The F1 error code indicates a refrigerant pressure issue, typically caused by either high or low refrigerant pressure within the system.
Insufficient refrigerant can cause pressure to drop, triggering the F1 error.
Dirt or debris buildup on the coils or filters can cause pressure fluctuations.
Malfunctioning pressure sensors may give incorrect readings, leading to system failure.
Ensure the refrigerant is topped up by a professional technician.
Clean the coils and filters to remove any obstructions that may be affecting airflow.
Have a technician test the pressure sensors for malfunctions.
