One Nozzle does not heating up anymore UMO

Posted · One Nozzle does not heating up anymore UMO

I have an UMO with two extruders.

Since the Heatercartridge (1st Extruder) has been damaged (Cable broken / short circuit?) and I repaired it, the Nozzle does not heating up anymore.

To check, if the Heatercartridge is still ruined I changed the pair of Heatercables (1st Heater/ 2nd Heater) and I had to notice that my repaired Cartridge heats up ! (at the 2nd Heater power connection on the PCB).

I am afraid, that my PCB (pcb 1.5.7, the green one) just at the 1st-Heater-power-connection is ruined.

If so, which electronic parts I could exchange...?! Or is there any other reason to fix that problem?

I would be very glad if I could get any piece of advice!
