Range is approx 20 years old. Pilot is lit but oven won’t light
If the pilot flame increases when you turn the thermostat “on” then the problem is a bad gas safety valve.
If the pilot flame would not increase then the pilot assembly has to be replaced.
The model number you posted does not come up. Verify and repost it.

Gene,
The model number is correct. The range is about 25 years old.
In that situation whichever part you need call the APP customer service, and they will look up for the part through the microfiches.
