Hello, I am unable to find that diagram on line, and it looks like others in our group cannot find one either...have you looked for one glued to the back side of blower access door?

About how old is the unit? Is there a printed circuit board involved?

If there is a printed circuit card involved you can try disconnecting one of its outputs at a time until the fuse holds
