This is a very good thing to check…regardless of the current state of the furnace. Make sure to have a standard blue 15a fuse in place.

That said, if the current issue is that we’re getting open propane valve but no ignition attempt then I would suspect the main board. Maybe it’s been glitchy and has now completely failed.
