1. Turn off the air conditioner and disconnect it from the power source. Wait for approximately 3 to 5 minutes before reconnecting the power. Then, turn the device back on and check if the issue is resolved;
2. If the problem is not resolved through a power restart, it is recommended to apply for after-sales service for further inspection. A professional technician can diagnose the issue and provide the necessary repairs to restore normal operation.
