If you cannot adjust the fan speed of the Mijia Air Conditioner GentleAir Inverter 1.5 HP using the remote control, please follow these steps to troubleshoot:
1. Check whether the remote control battery has power. If depleted, replace it with a new battery.
2. If the battery is functional, check whether the remote control display is working and whether other buttons respond.
3. Please confirm whether you can view the fan speed level on the LCD area at the top of the remote control, and adjust it using the fan speed button.
4. If the remote control is functioning properly, ensure the air conditioner is receiving the remote control signal (listen for a beeping sound).
5. Please turn off the air conditioner for 3 to 5 minutes, then restart it and check whether it can be restored.
6. If the issue persists, please apply for a professional after-sales inspection.
If you cannot adjust the fan speed of the Mijia Air Conditioner GentleAir Inverter 1.5 HP using the Xiaomi Home App, please follow these steps to troubleshoot:
1. Remove the device from the Xiaomi Home App, reset the Wi-Fi network of the air conditioner, and control it using only the remote control.
2. Check whether the issue occurs when using other remote-controlled devices at home to rule out signal interference.
3. Please confirm whether the connected network is working properly. Try switching to a different network and then attempt again.
4. If the issue persists after the above troubleshooting steps, please apply for a professional after-sales inspection.
5. If the issue is resolved, check whether the Xiaomi Home App settings are affecting operation. You can reset the Wi-Fi network of the air conditioner, reconnect to the Xiaomi Home App, and clear previous data.
