Blown fuse for heated bed Prusa i3
Hi all, I have a Prusa i3 Printer I recently bought on eBay. Today was the first day I had it running and printing properly I had it printing probably about 6 hours solidly. I had a break for some food and came back and noticed the bed wouldn't heat up. After a bit of investigation I found a blown fuse on the board.
See photo, under the power connector fuse on the right.
It is marked LF15a.
I believe it is one of these 2

Am I right in thinking the voltages specified are max and I will be fine with the 65v ones?
I also had other questions, any idea why it blew? I read somewhere these beds can run at 180c, I had mine set at 110c which translates to 60-65c on the glass surface. Was I pushing it too hard?
Thanks Chris

I think that fuse opened up due to a bad fuse socket. You will need both.

Sorry for the delay,... Yes, you will need to de-solder and re-solder a new socket on the board.

I have this exact issue (mine looks even more burnt out) did you manage to fix it yourself in the end?
Sourcing a new socket has been a real pain for me.
