Thank you for your question and I understand your concern.
Your model range does not have an electronic ignition system. It has standing oven pilot light, an oven thermostat, oven safety valve and an oven pilot assembly.
The way the oven operates is when the oven thermostat is turned on; the oven thermostat provides a little bit more gas flow to the oven pilot assembly. The oven pilot flame should increase a little and shoot downwards on the thermal bulb. The flame should engulf the thermal bulb which is attached just below the pilot flame. The thermal bulb is permanently attached to the small little copper capillary tube. The thermal bulb and the capillary tube is part of the oven safety valve. When the thermal bulb is engulfed in the flame, it heats up the liquid in the thermal bulb which causes the liquid it to expand which cause the oven safety valve to begin to open and let gas flow into the bake burner at which time it ignites off the pilot flame.
Make sure the pilot assembly is not dirty or restricted with any soot. If the pilot flame increases when the oven thermostat is turned on and the flame engulfs the thermal bulb, the oven safety valve will need to be replaced.
I was going to provide the part number for the oven safety valve but the safety valve is no longer available.
It's likely a good time to consider shopping for a new gas range.
