Out Maytag Gemini Gas range lower oven does not work in BAKE mode at all. The lower oven will work in AUTO mode and will heat up and hold the temp between 325 and 350 just fine. The lower oven does not seem to light up. When I light the upper oven, there is a gas smell before it lights up and then it works fine. I am not sure what is wrong as fixing an oven is new for us--we've done our dishwasher, fridge and dryer. Any help determining the cause of the problem would be appreciated. Thanks in advance.
