Hi,Can't your heating bed heat up properly? You can check if your heating bed line is connected normally. If you unplug the heating bed line from the motherboard, if the temperature shows -14.

Hi,If the hotbed cable is unplugged but the temperature still shows high temperature, the motherboard may be defective.

yes but I'm not sure that it is the version 3-1 used by the A10M. the manual is not the right one.
