Hello, I have a Prusa i3 Mendel and during a printing my heated bed stoped working. Anyone could tell me what happened?

Thanks!

Power stopped flowing through your heated bed. Either the + side isn't getting enough power or the - side isn't being shunted to ground when desired.

Have you got a fan blowing over your Ramps board (that's if you have Ramps). The yellow fuse has an issue where it can shutdown prematurely due to overheating.

Replace the standard ramps MOSFET for the bed to IRLB8743PBF MOSFET, N CH, 30V, 78A, TO220 or similar, the standard one isn't good enough and will get too hot and eventually fail. The replacement won't even get warm.

waitaki how do you fix that problem ? i think that could be my problem as my heatbed fails to reach the correct temp although the hotend reaches it fine having said that, when i turn both on the temps drop. the yellow fuse' do reach a significant temp i have noticed

Just install a fan, permanently connected to 12v power.
