Help! I reinstalled my exhaust fan wrong and I'm afraid I may have fried something. I blew the main fuse and replaced it already. It's hooked up correctly now, but as soon as I plug it in both the fans start spinning. Manual feed and high fan buttons both work. Automatic mode and the multiple fan speeds are not working. There's a fuse on the circuit board that I haven't replaced, but it looks decent. Any help would be much appreciated!
