Possible Causes
How to Fix / Troubleshooting
Safety: Refrigerant circuits are sealed and under pressure. Only licensed technicians should connect gauges or open the system.
User checks:
- Airflow: Ensure both indoor and outdoor coils and filters are clean and fans are operating.
- Operating conditions: Confirm doors and windows are closed and the space is within the unit’s capacity.
Technician checks:
- Pressure test: Connect gauges to verify system pressures and confirm low charge or blockage.
- Leak detection: Use electronic leak detector or dye to locate leaks. Repair leaks and evacuate/recharge with the correct refrigerant type and weight specified by Klarstein.
- Sensor/PCB: Test the pressure sensor and replace if faulty. If sensor is good, the main PCB may need replacement.
Do not attempt to add refrigerant yourself; improper charging can damage the compressor and void warranty.
