I have had my Creality CR10S-Pro about 2 tas by now. It has functioned well. Some filament jams only. I still consider myself a beginner though J

After a jam a couple of weeks ago I noticed that the fan pointing at the nozzle (fan2, placed on the right sid) wasn’t running.

I bought a new fan, tested it was working before installing it to the machine. When starting the machine I found that the new fan didn’t run. Fan #1 was running)

I checked the wiring , which seems to be ok.

Since there are separate cables to fan1  and  fan2, are they not supposed to ran at different times?

I would be greatful  for any help and /or tips how to solve this problem..


Best regards
