I have both a breaker box and a fuse box. The breaker box is fine. The fuse box, not so much. Its only purpose is to power the dryer. I had an electrician come out a few years ago to see if the fuse box could be updated to a breaker box and they wanted to replace all the wires quoting code etc. For cost reasons I didn't do it.
Here is the fuse box in question:
At the time I was going through a 30 amp fuse once a week. Only on the left socket. When the fuse would go out, the dryer would still run, only it wouldn't heat. I found that if I only use timed drying, the fuse doesn't blow. It was the auto mode that was killing the fuses. So I stopped using auto dry.
Fast forward to a few days ago. Dryer reported a 95% blockage. It wasn't blocked, I took the dryer apart and check both the thermal fuse and heating elements. Continuity checked out. Vent was maybe 3% blocked, cleaned it. Checked the fuse box, and there I saw the red wires were scorched with corroded copper. Never a good sign. The fuse, done for. I pulled the fuse and the ceramic disk in the fuse slot crumbled. I checked continuity and it has an irregular pulse i.e. not constant. So the box is and probably always was dead, just not dead enough to fail obvious inspection.
I found a fuse box on Amazon.
But I'm not sure if I should make the attempt or not. It looks like a 1:1 replacement. However I've never done something on this level; swapping outlets and replacing light fixtures being the closest to electrical work, and I'm reading that there are some times laws and permeants that I might need. I'm also not sure how to punch the metal circles out. The red wire is scorched, so I'll need to clean it. I'm reading that I can remove the corrosion with baking soda.
I live in Cincinnati. I would like to hire a electrician, but the last one aggressively pushed for a rewire and I'd rather not have my walls torn out and not have electricity for a week. A simple replacement is in order, but I'm worried any electrician won't do it because of what the first one said about codes etc. and I'll get hit with a visitation fee with no work.
So my big question is, how difficult would this replacement be?
Should I eat the enormous cost of an electrician? (I'd rather not)
