Also a good diagnoses video on you tube

If you want heat at 80 then go for it the stove don't care
what the temp. it is outside

if it blew the main fuse there is a reason for it, while the stove is out and accessible open her up and check all your wiring make sure you do not have a wire that may have touched to a hot spot in the stove and shorted. also its not uncommon for an igniter to short out when it dies which would cause a blown fuse when startup is initiated which would be why it didn't blow until you pressed on button

Make sure you are using a good power strip to clean up the electricity before it powers that board. The boards are not cheap!
