Ovens etc with electronic clocks, also have an electronic shut off valve for the gas. The pcb/clock pcb could be faulty, not opening the valve or the valve could be faulty. one or the other, was taking the fuse out, until it went open cct, instead of short cct. But one or maybe both need to be replaced before the oven will work. It is a safety feature, Plus a pain in the *** sometimes.
I can answer this question...
