Fan failure and heatbreak thermistor disconnected error
I just completed the upgrade from 2 to 5 heads following the step-by-step instructions. When I go to reset the calibration I get the error message (heatbreak thermistor disconnected). what could be causing this? The system is also failing the fan test, the fan on the 3rd head does not stop running and the results are showing that heads 3 and 5 do not pass. Any suggestions on resolving these issues?
