Hi all. I walked over to check on my snakes like I always do..and as I got closer, I realized that the backlight on my Herpstat ND was off. I take a closer look, and make sure all the connections are plugged in, and they are. So I unplugged it from the wall, and plugged it back in, and it's back on. The temp dropped all the way to 75 on the heat tape, so it had been off for quite some time, to reach ambient temperature. Not cool

Has anyone had this happen before? I have no clue what could have caused it. I have had it for 3 years without a single problem. Any clues? The socket next to it has my incubator plugged in, and it was still up and running, so it shouldn't have anything to do with a fuse.
