There is a spark ignition plug near the burner. It could be dirty or the lead has come off. If you can hear the sound of the spark, that would mean that power is getting to the plug. If the problem continues you might consider buying a hand held gas igniter. Far cheaper than a service call.
There is a VERY complete tutorial on how to remove your oven door for hinge replacement or just for cleaning at https://www.youtube.com/watch?v=6YFTYWsiO1M
The narrator is clear spoken and the instructions are easy to follow not to mention the fact that you can go back to it any time for a refresher if you need to. Most ovens are very similar in how the doors work so this should do the trick.
then watch the next one for the cleaning directions

I would add that you might want to wear rubber gloves. As a 5' woman I found that the oven door was a little heavy and the extra grip is handy. Be sure to have something ( like a small coffee table) to set the door on as soon as it's loose to prevent back strain.
If you are seeing the bubbled paint on wall when you open the oven door, it is more than likely heat loss past the door gaskets. They are easy to install clip on gaskets

I am a retired career chef, and had this one oven with choking CO in an airport catering kitchen. We had it serviced and it was fixed. It sounds like yours is not getting enough air mixed with the gas. Adjusting the gas is one thing but the venturi to the burners can partially block and unburned gas spills over. Remove the burner and venturi and boil it out in whatever you boil your fryers out with.
Are you on mains gas or propane because the jets are different.

Here is text followed by a YouTube. Possible reasons why your oven won't turn on even though the gas and range hood are working:
Igniter: The igniter is responsible for lighting the gas in the oven. If it's faulty, the oven won't turn on. You can check if the igniter is working by looking for a glow when you turn on the oven. If there's no glow, it's likely that the igniter needs to be replaced.
Wires: The wires that connect the oven to the power source may have come loose or be damaged. Check the wires for any signs of damage or looseness and replace them if necessary.
Safety valve: The safety valve regulates the flow of gas to the oven. If it's faulty, the oven won't turn on. You'll need to hire a professional to repair or replace the safety valve.
