Shorted fan 0 wires. Now fan won't stop.
-
I was doing some wiring of my part fan (fan0) and I forgot to turn off the printer. I shorted the two wires together and the board rebooted. Now that I have it all rewired, the fan is on 100% all the time (even when not printing). Does that seem like how it would fail if I damaged my board?
If so, I assume it is possible to use a different fan port and somehow map that to my part fan? -
@erice555 Yep, that is exactly what happened. Remapped it to fan 8 (duex board) and all is well.

Yes it's likely the mosfet was blown and failed in the on state.
the mosfets can be replaced if you're handy with an iron.
