What happened?

The printer is showing the message "Check the heatbreak thermistor wiring for possible damage."

Error name: Heatbreak MINTEMP Error

Error code: #26211 (MK4S) #13211 (MK4) #27211 (MK3.9S) #21211 (MK3.9)

The error is shown when the heatbreak thermistor drops below 5 ºC at any point.

How to fix it?

Access the LoveBoard. Check if the thermistor is connected correctly and if there is no damage along the cable length.

If you have a multimeter, it is possible to check the resistance of the cables to verify if they are damaged. For that, use our Multimeter usage guide.
