what is broken!
during printing the actual temperature and the target temperature is set to 0 and there comes the error Err: MinTemp.
Temperature Senosor and heating is already exchanged. Error remains the same.
This indicates an open on the thermistor of the print head
Check the middle (Green) connectors on top of the print head make sure they are tight.
That’s fixed everything.
I’ve got the same problem. The thermo sensor is connected right. I was printing last night and everything was Fine. This morning the ERR MINITEMP came on. The heater is connected right as well. Any other reasons for that?? Please help
aufbruch1963 glad that helped.
Check the screws make sure they are tight.
Try removing the wires from the middle connectors
At room temp you should read around 100K
Min temp means you have an open on the thermistor.
Check all of the connectors on the print head (large block) and on the mother board.

spare whence?
This is very strange to have this trace burned (it looks burned) as almost no current is flowing through that trace (thermistor does not require a lot of current). Can you check your connections on the bottom to see if you did not switch anything around?
You can normally order spare parts from your dealer.
