Everything electronic on this brand publishes a condition — 414 of them are decoded on this site, and a four-character code names the cavity and the board that reported it. That is an unusual amount of help, and the oven pages here lean on it heavily.
The gas half says nothing at all. There is no code for a burner that will not light, a simmer that will not hold or a griddle that stays cold, and there never will be. Those pages carry the diagnosis themselves, which is why they are longer on what to look at and shorter on what to read.
