Using a Crown xs900 for a stereo PA system
The red fault light's been tripping inexplicably
This is the third time it's happened, usually works after overnight chill out
but we'd like to figure out a solution
can't figure out how to replace fuse

I don't think replacing the fuse will aleviate your problem! :)
You have a potential fault coming; I recommend that you bring the amp to your local authorized Crown service center for an evaluation.

What is your usual speaker load on the outputs?
What is your usual AC source (15/20/30A)?
Does the unit go thermal before going to Fault?
Does the Fault light trigger at random? Do both Fault lights appear at once?
Does the Fault indication appear at the beginning, middle or end of the gig?
Does the Fault indication eventually leave?
