My oven is malfunctioning? I'm cooking a ham and I have the oven set to 350,...

I'm cooking a ham and I have the oven set to 350, It smells deeply like gas within the kitchen and the oven itself is not getting as hot as it should. Its been cooking for approaching 20 to 30 minutes now.

So any concept?

Thanks in advanced.
How do I bypass the lid switch on...
Answers:    I would recommend turning your oven stale and calling a repair man. If you can smell gas, your oven is not operating properly. Make sure you open a skylight to air out your kitchen and do not night light any flames.

its probably the fumes coming out of the vent at the top of the stove, turn on the stove vent fan on high-ranking,
if you don,t have a stove vent unequivocal a window 1 or 2 inches,
