The fuse on the board is a timed (aka slow blow) fuse as shown by it's marking i.e. ***T***3.15A 250V - see image below.
The T = timed.
When the power is first connected the inrush current is several times more than the current needed to operate the device. This current lasts for approx 5-10mS and then subsides. A normal fast acting fuse having the same current/voltage specifications would blow immediately but timed (aka slow blow) fuses are designed to hold until this current subsides.

If the fuse is blown i.e. tests OL or open circuit, there/s always a reason for this to occur as normally fuses don't fail of their own accord. So perhaps buy two or three fuses as you may need them in case the first blows as soon as power is applied. You'll then have to find out why this happened.
