Nate, try this; open the oven door and manually depress the spring-loaded button on the side of the oven opening, (I can't remember which side of the oven it’s on; you DO have an golden oldie!). This allows LP to freely flow to the pilot assembly. Be sure the LP container is opened and the pressure is correctly set to 11.0 inches of water column. The pilot flame should stay lit when you release the button. If it does, close the oven door. After setting the temperature on the thermostat, it will seemingly take an abnormally long time for the main flame to ignite. If you open the oven door to check, however, the flame will not light. A hidden lever encased in the side of the oven unit pushes the LP safety valve only when the door is closed. The fan should engage sometime after the burner has produced enough heat to be delivered through the vents at the bottom of the oven.
