i hooked up another good fan,pushed defrost and it worked for a moment and then blew a white fuse at #3,i had put a white fuse in ,but it was supposed to be red,i had taken original red and used it at another fuse earlier,so it seems red fuse originally somehow failed without showing any sign of failure,now i have heat again.weird
