I caught the 2 undercabinet lights flicker out of the corner of my eye and realizing the bulbs just didn’t both go out at the same time, went to check it, and nothing works. 
I checked the outlet and it is fine. The only thing running on the unit at the time it went out were the two undercabinet lights. I was thinking I would try to replace the fuse and see if this would fix it - if not, I’ll probably get a new one, but the microwave/fan over-range unit is only 3 years old and deluxe, so I’m thinking it might be worth a try. Anyone have any experience with this?
