Is it normal for the Xiaomi Induction Cooker Lite to automatically turn off when powered on and why doesn't the knob switch work after powering on the Xiaomi Induction Cooker Lite?

In the powered standby state of the Xiaomi Induction Cooker Lite, if there is no operation for 10 minutes, the heat indicator will go out, and the product will shut down. You can turn on the product by holding and pressing two seconds any knob or rotating the knob to wake it up.
If the knob switch can’t work, refer to the following troubleshooting methods:
1. Please check whether the knob switch is deformed or cracked;
2. Confirm if there is any foreign object interference affecting the rotation of the knob.
If the above operations are correct, please contact the local after-sales service center for repair assistance.
