Range only smells when oven is used
 

Hello ALL< Happy New Year!:)
My gas oven only smells when I use it or when the pilot light ignites throughout the day to keep the temperature.

Do you know what it might be?

The ignitor went out the day after I started smelling it. The gas company even came out and couldn't find a leak. I replaced the ignitor but it still smells. Its absolutely terrible when using the oven because the gas fills the whole house.

At this point I only smell gas when the pilot light ignites, I am scared to use the stove now.

The range works fine but I do notice orange flame in the past month or more. Is this normal?

PS Forgive me if I am asking this the wrong way. I just want to know the cost of repairing:)

Please help..The smell is making my cat walk into walls.
