Thermistor error!



  • To whom it may concern,
    I am writing because I am using a Creality CR-10s Pro V2 and the issue that I have is that for some reason when I try to print, I get the following warning:
    Thermistor Error! Cycle Power! An issue exists with the bed or nozzle temperature sensor. Connect to serial monitor. If reading is 0, condition is open. If too high, condition is a short to ground.

    That happened after the nozzle temperature was shown to be at "357 ºC" (but it actually was at room temperature. It could even be touched).

    Then I decided to turn off the printer, and then on again. Apparently, it was working "fine" again, since the temperature of the nozzle now was read correctly. But then suddenly I got again the same error:
    Thermistor Error! Cycle Power! An issue exists with the bed or nozzle temperature sensor. Connect to serial monitor. If reading is 0, condition is open. If too high, condition is a short to ground.

    So now the current state is that I can even start a print, but then suddenly I get the error just mentioned, even having normal readings both for the bed temperature and the nozzle.

    I was wondering if I could get further information about how to fix that error.

    Best regards,
    Xabi



  • Dear @Xabi

    Provide machine manufacturing code
    2. Please unplug the thermal wiring and turn it on again. If the temperature is still very high, it may indicate that there is a problem with the motherboard. If it shows about -14 degrees, it indicates that it is a thermal problem. Then measure the resistance of the thermal sensor and it is about 100K normally.
