the poly fuse on some ramps are cheap made...and blow quickly all will eventually start blowing as most heatbeds pull from 11-12 amps when they first come on.
the best way to fix this is what i did that is remove both poly fuses and replace them with mini blade fuse holders and put a 15 amp in place of the 11amp poly and a 5amp in the other then if one blows it is easy to replace...
tho you will want to look for your short first as that is the only reason one of these will blow.::o
