The most likely cause for the oven not to light is a weak igniter. I thought at first it was alright because it did glow red, Apparently it didn't draw enough current to allow the safety valve to open. The new igniter fixed it - 3 screws and a plug-in connector - all done. The stove top igniter was a little tougher. the burners were attached by screws and the screws were badly corroded. I had to drill them out. Also, the igniter was held to the bottom of the burner with a badly corroded screw. That screw had to be drilled out and replaced as well. Once the new igniter was in place, the burner lights as it should. It was easy to get the right parts by providing the make and model of the stove. The price was right, too.
