If your Mijia Air Conditioner Pro Eco A+++ 9K is not starting, please follow these troubleshooting steps:
1. First, check if the power cord is properly connected and the plug is inserted correctly;
2. Check if the socket is powered. If using a power outlet, you can try using another appliance to check if there is power (the air conditioner will emit a beep sound when powered on, indicating that the power is normal);
3. Check if the remote control batteries are depleted, and try replacing the batteries;
4. Use your phone's camera to point at the remote control and check if a signal is being emitted. If you see a red flashing light, the remote control is functioning properly;
5. If connected to the Mi Home/Xiaomi Home APP, you can try turning on the air conditioner via the APP.
If the issue persists after the above checks, please contact the after-sales service for inspection.
