I have an ignition lockout code on my oven, How can I fix it? Southbend Convection oven. Burners will light but not stay lit. Code light flases ignition lockout.

The 40 error code indicates a failure of the cooktop lockout board. The cooktop lockout board is not communicating with the main EOC electronic oven control. This could be a loose wiring harness or either the EOC board or cooktop lockout board is faulty. This type of diagnosis will require using a volt/ohm meter. If you decide to check the harness to the boards you will need to remove the back panel for access.

you cannot light the pilot on that oven manually. that oven is eletronic ignition. take off the panel under the doors, turn on the oven, and turn the thermostat to 350.
if you see sparking on both the right and left burners, you and it doesnt light, you need to see if the gas solenoid on the right side of the burner is getting power. if it is and nothing lit relace it.
if it is not, replace the ignition board

I have one that won't light at all, what could the problem be?

burner wont stay light

Gas does not ignite. No spark. No Ignition light is not ON.
1. Shorted electrode on igniter/flame sense.
2. Igniter cable (high voltage) OPEN.
3. Heat relay malfunction.
4. Centrifugal switch in blower motor inoperative.
5. Transformer inoperative.
6. High limit thermostat open.
7. Interconnecting wiring malfunction.
8. Ignition module malfunction.

Sparks but gas does not ignite.

1. Gas solenoid valve off or inoperative.
2. Manual gas valve closed.
3. Gas supply OFF or insufficient gas pressure.
4. Inerconnecting wiring malfunction.
5. Igniton module malfunction.

If the gas valve is on(no continuity) then yeah that is it, keep in mind the ignitor could be weak. I didn't notice where you replaced the ignitor and you say it is working so that means the gas valve has continuity. You need 37 ohms on that ignitor or a total amp draw of at least 3.5 to open that valve.I have a video: HERE

The pilot light must be lit and stay lit before you will have any propane coming into the oven. This is a safety feature.

Southbend does not have their information for your steamer on-line. You can get your schematic/diagram by contacting them

Depending on your local code, you will need an exhaust hood due to the byproducts of the gas burning. Some locals allow for electric ovens to go without hood. Gas units generally require a hood system with proper fire suppression equipment. You may want to check with your local fire and building inspectors.
