First of all, double check your operators manual settings to ensure your oven is not set to "Sabbath" mode. If this mode is set, it will disable the oven features. Sometimes this mode can inadvertently be set if you experience a brief power outage, or accidently push the wrong buttons.
Now...if it's not as simple as that you will need to check to see if your igniters are getting the proper voltage. It's kind of hard to do this without seeing your wiring diagram, but I would check to see if the igniters are getting the proper voltage from the control board, first. The easiest way (I'm assuming) would be to trace the leads from the igniter to where it connects to the electronic range control (ERC) board. This a GE, correct? Since this is a GAS oven, I'm also assuming the source voltage is 120VAC. If the circuit board is showing a proper display, that tells me you're getting proper line voltage to the circuit card. There should be a separate circuit for the BAKE and BROIL functions. They should work independent of each other. When you set the oven to BAKE or BROIL, you should hear a relay click as the circuit energizes (that is...most of the ovens I've worked on you could hear a relay, I don't know about yours). If you hear the relays clicking on the circuit board for each function that tells me each circuit relay is working. A voltage at the output of each of these circuits should indicate approx. 120VAC. NOTE: It is recommended that you take voltage readings by checking from NEUTRAL to the HOT TERMINAL.
Have you physically checked each igniter? The igniter bar should be intact and not broken. Unplug the range and locate the igniter connector plug by tracing the two wires. This will either be an actual plug, or wire lugs. Disconnect each igniter and perform a resistance check on the leads connected to the igniter. The resistance reading should be fairly low (usually close to a SHORT). If it reads OPEN, the igniter is bad.
Now...this may seem a bit much. If you get confused, please post back and I will try to guide you in the right direction. Good Luck. I hope this helps you.
