Small chip burned out.

  • Hello.
    My printer had a bad connection of temp sensor and I was leaving it for a few minutes.
    Then small chip near by CPU made smoke and burned out.
    Maybe the connection to the sensor was short circuit.

    After it was burned out, I turned the switch on.
    But found there was no problem.
    Even the temperature was shown at the right temperature.
    So my question is
    What was burned out ?
    What was this chip for ?
    Do somebody know the part number of this ?

  • looks like the VSSA fuse, which suggest a short in thermistor for bed/hotend to a heater.

    think there may different sizes for different revisions of the board however
