Duet 2 Wifi Blown 1A Fan Fuse
-
Hello,
I was recently using a multimeter to test the voltages across my fans on my Duet 2 Wifi as I was having issues with heat creep and thought that maybe there was insufficient power going to my 12V fans. While I was using the multimeter on one of my fans, I accidentally touched the two tips together and heard a pop as the fans stopped working. The board still turns on, and I am able to do everything else, but the fans do not work. Luckily, it seems that I've only blown the 1A fan fuse. I confirmed this using the multimeter again and it seems that only one pin on the fuse shows a voltage, and the metal bit in the middle literally looks disconnected.
Anyway, I was trying to find a 1A mini blade fuse online since I am not familar with electrical supply stores in my area. I was only able to find an amazon posting for fuses that go down to 2 A:

I would grateful for any wisdom anyone can share with me.
Sincerely,

not 100% sure what current rating the jumper for Vfan has but after thatthe only issue I could think would be the fan wiring might fail before a 2A fuse if they are thin and you would have a prolonged fault as opposed to a short circuit.edit: ref below, board can handle it but still your wires might not in the event of long term overloading as opposed to a short term short circuit.
