I have a fridgidaire FG6RC 080c-16B gas furnace and had it installed about 8 years ago. Last winter it shut off on me and I opened the panel and noticed the little 3 am fuse on the board was blown. I had someone come out and look at it. They diagnosed it as a bad themostat and connected a new one. About a month ago the same thing happened. I looked at the board and there was a bad 5amp fuse in the spot that says....Max fuse amp 3. So the guy must have put a 5 amp fuse in and its still blowing them. Any help would be greatly appreciated.
I just notice the green wire towards the sheathing is exposed. I'm not how this got this way (probably when originally stripped). However, these shouldn't be touching the panel so I don't think this tripped it.
