all 3 fans not working.

[Puppet172]

All of a sudden all 3 fans on my printer stopped turning on when i turned the duet wifi board on. I disconnected them from the board and powered them directly with the powersource to see if they would work and they turned on with no problem. What could be the problem here?

Blown 1A fuse, if it's a revision 1.03 or 1.04 Duet WiFi or Ethernet.

@dc42
So what is the best way to go about fixing this?

@puppet172 R&R the fuse if that's the issue. verify that the fan wiring is also in good working order and not shorting out anywhere.
