Oven not working

Hi. My 2004 3023 oven won't light. the 3 top burners work fine and i can get the pilot light to ignite and stay lit. The problems is the pilot won't ignite the oven. As I turn the knob only the pilot gets real big but never turns on the oven. Any suggestions? Thinking it might be the oven safety valve. Thanks

You might try cleaning the burner with a tooth brush in the pilot area. Other then that maybe something in the thermostat.
