The pilot is burning but burners are not lighting

switch the dial to the indicator which shows the top grill,usually this is a black line with a squiggle under it.

On the main bake burner is going to be a small pilot burner,got to lift off the oven floor to get to it. It is going to look something like this picture and is attached usually to the side of the main burner.To light the pilot,push that red button light the small pilot burner..hold in the red button for about 20 seconds..release the red button..pilot should be on..if goes off the thermocoupler is going to be in need of replacement

Most gas ovens that aren't electronic ignition usually have a pilot light.
Usually one in the oven area and one for each burner. (Sometimes shared between two burners.)
These pilot lights must lit at all times...otherwise it won't light up and you'll smell gas.
Usually the pilot light is in the very back of the oven and can be seen with the broiler drawer opened.

There is a small set screw located at the pilot light assembly in the oven and also at every burner.
This allows you to adjust pilot light up or down, thereby letting you set pilot light flame to a level that doesn't get blown out by a draft...or you can turn it off completely.

If you use that set screw to turn off the pilot light gas, you'd need to strike a match to light the oven or burners everytime you needed them.

Instructions

1. Access the burners inside your oven by removing the access panel in the front of the oven or by opening the broiling drawer, depending on your particular model.
   
2. Determine if the pilot itself is lit, since some ovens have a small flame on the pilot at all times that then grows and extends to the burner when the oven is turned on. The lack of a pilot flame indicates the oven thermostat is malfunctioning or there is a problem with the gas hose. Check the pilot itself to see if it is clogged with debris or grease that could be preventing the flame from staying lit.
   
3. Determine if the pilot flame will grow if it is lit by turning on the thermostat. If the pilot flame doesn't extend, the thermostat itself likely needs replacement. If the flame is extending but the gas valve is not opening, the safety valve could be dirty or defective. The flame should be blue in color. A yellow flame indicates the pilot is dirty and is not burning hot enough to get the main burner to ignite.
   
4. Light the burner on the top of the oven with a match if the igniter doesn't appear to be effective. If it lights manually but will not light automatically, the igniter is likely faulty. Do not do this if there is a heavy smell of gas in the kitchen, since there could be a risk of a fire. In that circumstance, turn the oven off, ventilate the room and call a technician.
   
5. Listen for any sounds of gas hissing or a clicking sound indicating the oven is trying to turn on. If there is no response from the oven at all, the gas may not be functioning properly and will need to be examined by a technician for safety purposes
   

Bakers Pride used several different safety valves over the years. If your oven has a pilot valve that has a beige know that you hold in and turn to light the pilot, then after it lights you need to turn the beige know another half round to the "on" setting. If you push in a red button to light the pilot, it may not be getting enough heat on the thermocouple where the pilot flame should be heating it up. Be sure the main gas valve on the front of the oven is turned to the on position also. On some models the pilot will light with the main gas valve in the off position. If you look at the pilot flame while it is burning, make sure that it is hitting the pencil sized thermopile enough to make it glow red. If not bend it slightly to improve the heating.

On standing pilot ovens the maker uses a safety device to kill the gas in case the pilot blows out. As long as the pilot is lit the gas safety magnet hold the gas flap open inside the safety valve.To save energy the pilot has 2 flames. The standby pilot keeps the cooper/nickel probe/sensor warm so the oven will light faster, the 2nd pilot is much larger, only appears when the oven control is turned on and this is what opens that valve. So when you turn the oven knob on the gas leaves the control and goes downtown to burner land. If that pilot is lit and that slow opening flap inside that valve is open, then the gas will enter the burner tube and ignite when it hits the pilot. Pretty slick ain't it? So what can go wrong? With age the flap inside the safety valve will wear out, get weak, work a little, then take forever to light and eventually just goes bye bye. When you get ready to replace the valve it ain't gonna be adjusted exactamundo, you gotta tweak it. To do so after bubble testing for leaks and lighting the pilot you turn it on and observe the flames. It needs to be not more than half way up the flame spreader. If it is to small of a flame it will take forever to bake even a pie shell, if it is too much their could be burned bottom and in some cases fire hazards. OOPs.

The declining pilot light might be an indication it is being starved of oxygen by the main burners or some other sort of circumstance.

I have noticed how in a closed room without ventilation the pilot light soon begins to decline and then springs back again when a window or door is opened while the main burners are hardly affected.

This is the gas equivalent of sending canaries down coal mines and is an essential safety feature. If the pilot light declines very much the thermocouple bulb will not be heated and the gas supply to the main burners will be cut off. This is why the pilot light is set at an angle and the thermocouple bulb is slightly offset.

I am not sure if this helps but I hope it does.

replaced the control box that that governs the burner
