UM1 Head Fan always on after short

[antiklesys 3]

Hi everyone,

I was checking something out on the head fan and a small short happened on the fan wires. The UM went all off as a soft fuse detected the short in the power supply.

I power cycled the psu and the UM went on again but the head fan is now always on. I tried turning everything on and off several times, started prints and so on, but it's still on all the time. I also reflashed the firmware but no luck.

Any hints or suggestions on something to try?

I tried checking the voltage on the fan and it reads 19V.

Is that the correct reading i should be getting?

Any help is welcome!
