Hotend is not working

My hotend is reading -15 degrees and is not heating up. I have attempted flashing the motherboard, replacing the motherboard, and replacing the thermostat. Any suggestions?

    Welcome @Alex_M ,
    -15C means there is a broken connection between the thermistor and the motherboard. Do you know how to use a multimeter? If you can use a multimeter in continuity test mode, you should be able to track down the broken connection. I hope that helps!
