I was working on a light in the kitchen so I took the old school fuse out so I wouldn't be electrocuted. When I was done with light I put fuse back in to turn power back on in kitchen. Power works and light good but my flat top Scott ceran induction unit started flashing f47 over and over and I can seem to figure a way to hit the buttons to get it to work. Before I turned off power in kitchen. It worked fine. What's wrong? Pleas help
