Hi，You can try to remove the hot bed line from the motherboard, view the temperature display, -14 display, the motherboard is normal, you can measure the hot bed's thermistor.

The LCD shows 47 temperatures even after the bed temperature sensor is removed.
What should I do?

Hi,If the display of the hotbed is stable and abnormal, you can contact the platform you purchased or your sales to explain the situation.
I hope this can help you.
