Heatbed randomly stops heating

[Stocki83]

Yes the Heatbed randomly stops heating and goes down To room temperature. There also comes a Message nozzle temp-0 a few Seconds after the heatbed lost its temperature. And then most stupid Thing.... The printer don t stop Printing.... Of course without extruding... Anyone got an Idea??? Ty for your Help.

Nozzle temp error message usually means a problem with the hot end thermistor. Either the thermistor is broken or the wires routing from the thermistor are broken. Check for continuity from the motherboard all the way to the thermistor. If the wires are good, i'd suggest replacing the thermistor.

Hi dekes i have checked the cable. I think there is something wrong. Everytime i Touch the cable the heatbed works again for a time...

Hi, did you ever find a solution to this? I having similar problems. The heatbed stops heating but the error message is "Nozzle 0-Temp" or something similar. (obviously wrong since that pops up even if I'm not heating the nozzle).

I'm suspicious that it could be the little heatbed mosfet board overheating/gone bad.

You can open the PSU box and you can get more details.
We need to refer it.

Hi, there was a problem with the cable from Bord Inside to plug. And I think there also was a problem with the heatbed cable included the heatbed . Both things were resent by geeetech. After changing these parts.. The printer Worked for 20h without errors. Nice Support geeetech ty
