[Solved] Print Fan still not working after full rebuild and replacement.
I've loved my Mk3 for a long time, but a few weeks ago I started having sporadic "Print Fan Error" issues, and the self-test would respond with The extruder fan - > OK
Print Fan -> Fail
Check fan? Wiring error
Having looked up the issues, I purchased a new 5v blower fan and decided that I would take this opportunity to upgrade my machine to an MK3S with the upgrade kit I had if I already needed to preform disassembly to repair it. However, after completing the entire build, I still get the same error on the Mk3S firmware and no spin from the new out of box fan. If I lie to the self-test all other parts come back with an OK report. I've checked the wiring on both the new and old fans, and they seem ok, but the only fixes I can find online are to replace the fan or splice wires. Any other possibilities as to what's going wrong?
Update: Found the issue, the new print fan had a loose wire inside its own plug.
Remember: Always double check wire connection points!
