No the relay is upstream of the fuse. Only something downstream can be
the culprit.

The relay is really only used by that circuit as an easy place to
connect for power. The relay twin 87 pin feeds the fuse, not draws from
it. The relay is not being used as relay for this.

If you look at what draws from the fuse, connection T6/4 shows the power
from the fuse feeding 3 branches at that point. 2 of the branches, an
orange wire and a grey wire are on the other side of T6/4 so unplugging
T6 will remove those 2 draws from the fuse. If the fuse still blows then
the cause in the 3rd branch, a second red wire on the same side of T6/4
that connects to the fuse. The second red wire feeds the fan on the back
of the fridge, first passing through the temp switch mounted on the
fridge fins (where you can see it through the side vent grill). If
unplugging T6 keeps the fuse from blowing then the cause is either down
the orange wire or the grey wire. The orange wire feeds power to the led
circuit board. The grey wire feeds power to the faucet switch and water
pump.

Any more questions, just ask.
