Viking oven

Oven Repair (including Ranges and Cooktops)
1

I have an older viking range, 4 burner on top with griddle. Problem is oven, the left burner lights but right does not. there are no corroded lines. Ignitors get red and hot but no gas is getting to right side. Any suggestions? I am a recently divorced mom of 7, abandoned by dad and need some step by step help here. Thanx
