Haier · Air Conditioners
The system's function for detecting refrigerant leaks is malfunctioning, meaning it cannot reliably report if there is a leak in the system.
Click steps to track your progress.
Turn off the air conditioner at the main power switch or circuit breaker.
Wait for at least 30 seconds, then turn the power back on.
Monitor the unit for any signs of actual refrigerant leakage, such as reduced cooling/heating or hissing sounds.
Contact a qualified technician to inspect the refrigerant system and the leak detection sensor.
