What to do if the Mijia Air Conditioner Pro Eco 3.5 kW cannot start or power on?

If the Mijia Air Conditioner Pro Eco 3.5 kW cannot start or power on, please follow these steps:
1. Check whether the power cord is properly connected and the plug is fully inserted;
2. Confirm whether the power outlet is working. If using a power strip, test it with another device. When the air conditioner receives power, it usually makes a beep sound indicating normal power supply;
3. Check if the remote control batteries are depleted. Replace them with new batteries and try again;
4. Use a phone camera to point at the remote control and see if an infrared signal is emitted. A red flashing light on the remote indicates the signal is working;
5. If connected to the Mi Home/Xiaomi Home APP, try to power on the air conditioner through the APP;
6. If the issue remains after these steps, please request after-sales service for further inspection.
