I have had my gas oven for almost three months. It still smells up the kitchen when preheating. It is so bad it gives me a headache and if I open the door, my eyes burn. We are on propane, is there a different regulator or setting on the regulator we need to look at? The service company Whirlpool uses in our area is no help, if you can even get them to come out. Help. Any suggestions are good ones. Thanks, Cheryl
