Suggestion for the future -- If you have a problem that could be related to a blown fuse replace all fuses. It's cheaper and easier than replacing a bunch of other stuff then finding out it was a fuse all along.
quite working last winter. I removed all the fuses, and put a new fuse in for furnace
and another 20 amp fuse.
Many fuses can appear OK when looked at but are not. Also the connection to fuse can get corroded. Removing and replacing will sometimes clean the contacts.
