  This most likely means there is a short circuit on the wiring for the bed thermistor. If you unplug the bed thermistor plug from the motherboard, you should then get a mintemp error instead -- this would confirm the motherboard is ok.

  Hi Samuel. 

  Thanks for your reply. I will test it. So you mean I have to remove the cable from the heat

  Try to unplug the bed thermistor cable first (the two pin purple plug) from the motherboard, and then see if you get a min temp error then (negative temperature, will show around -15C) . If so, then there is certainly a short circuit in the wiring for the bed, or a short circuit in the bed itself.

  Thanks again. Will try later. Do you know if a bed from an A5 is compatible? I have one with mechanical issues.

  Oh dear... that probably means the motherboard bed temperature input is damaged 😔

  Thanks for your help. It looks like it’s not possible to by the board anymore. Then I will try to reactivate my A5 with the mechanical parts from the A5s
