If an inverter air conditioner turns off automatically without any apparent reason, even when the set temperature is reached, it could be due to a few possible factors:
Power fluctuations: In some cases, the air conditioner may shut off due to power fluctuations or interruptions in the electrical supply. This can trigger the AC's safety features, causing it to turn off to protect the unit from damage. If this is the case, you may need to address any electrical issues or consider using a voltage stabilizer to regulate the power supply.
Faulty thermostat: The thermostat is responsible for sensing the temperature in the room and sending signals to the AC unit to maintain the desired temperature. If the thermostat is faulty or malfunctioning, it may give incorrect readings or fail to communicate effectively with the AC. As a result, the AC might turn off prematurely. In such cases, contacting a professional technician to inspect and potentially replace the thermostat is advisable.
Refrigerant issues: If the air conditioner has low refrigerant levels or a refrigerant leak, it may encounter problems in maintaining the desired temperature. In order to protect the system, the AC might shut off automatically. It's important to have a qualified technician inspect the unit, check for leaks, and recharge the refrigerant if necessary.
Overload or overheating: If the air conditioner's components, such as the compressor or condenser, become overloaded or overheat due to excessive usage or improper ventilation, the unit's safety mechanisms may trigger a shut-off to prevent damage. Ensuring proper airflow around the outdoor unit and avoiding overuse of the AC can help mitigate this issue.
In any case, if your inverter air conditioner is experiencing recurrent and unexplained shut-offs, it is recommended to consult with a professional HVAC technician. They can diagnose the specific problem and provide appropriate solutions or repairs to restore proper functioning.
