Is my 5A polyfuse on my RAMPS board bad?

Hi,
My printer stopped printing during a few prints, and i found that the extruder had stopped heating, and the motors had stopped running. I wanted to verify whether it was my fuse that had turned bad or there was some kind of short in my circuitry.
With the power switched on, none of my appliances drew any current. However, the RAMPS board drew about 0.16 amps.
Is that normal?
If that is normal, does it mean that my fuse needs replacement? Because none of my loads seemed to draw unnecessary current.
Thanks in advance.

The poly fuses an be problematic, if your not sure replace them with automotive fuses.
