I will tell you why you dont smell any gas here in a minute.
When you try broil do you see that orange glow for that?
Ok then your problem is going to be the bake ignitor. This has to heat up to a certain degree inorder for it to send power to the gas valve therefore opening up the gas valve. Thats why you dont smell anything by the way thats a safety.
Am I able to repair the bake ignitor. You are telling me the source of the problem, but not how to fix it. Please let me know if I need to hire an appliance tech or this can be done by me.
Im sorry but you didnt not ask me how to fix this.You just asked what could be the problem.But yes sorry to say that you will need a tech to change this out for you. Thanks and your welcome.
