Duh - Problem with new Suburban furnace not Atwood

OK, there is no fuse. IF you do indeed smell LP at the exhaust that means that sail switch is operating. On a Suburban, if you get LP smell and no tic tic tic, that means that either the Piezo wire is grounded(not likely) or the spark electrode is too close to either the burner or the case above the burner. Regardless, the furnace will have to be pulled to check the burner and the LP orifice and the gap on the spark electrode. Doug
