Customer: The convection oven wont heat up
JA: Do you plan on doing the work yourself?
Customer: Yes,Im not an appliance guy but Im a plumber and gas contractor so if its gas related i should be fine.
JA: Anything else we should know to help you best?
Customer: The upper oven and range burners work fine. Its 2 years old

Hello. My name is ***** ***** I'll be helping you with your appliance question today. Please wait a few moments while I review your question.

Since the upper oven and burners still work, you'll need to test the lower oven igniter. Turn the oven on and see if the igniter glows if you remove the floor inside oven and monitor the igniter mounted to the back of the bake burner. If so, then use an amp clamp to see if it's drawing 3.2 amps. If not, then the igniters need to be replaced. If they do draw 3.2 amps, then your oven gas safety valve is bad and would need to be replaced.

Now the last option would be if the igniter does NOT glow at all. Then you'd need to test power between the 2 wires going to the igniter. If you have 110 volts when the igniter should be glowing, then you have a bad igniter. If you don't have 110 volts on either wire to ground, test each wire compared to ground. If you don't have 110 volts from either wire to ground, you have a faulty control board. If you have 110 volts from one wire to ground but not between the 2 wires, your oven gas safety valve is bad and needs to be replaced.

The igniter has a 1/2" piece broken off on one side,it's laying in the bottom. I'm guessing that could be the problem

Aye that definitely sounds like it. The part number you need is WB13K10043 and below is a link to the part.
