Dana... Do you have multiple FM 100s? If so only one should have the GFI fuse. Broken panel with water getting into glass? Turn it off and wait 5 min and turn it on. Usually clears it especially if it's a faulty nuisance trip. Have had numerous FM 100s give faulty afci errors. Removing the.afci boards always resolved this issue. But of course check all you connections leading to and from the cc. Keep a few extra 1A gfi fuses handy....you may need a couple to test it all out. Keep us posted. Good luck Kirpal
