I have a GE profile gas range with lower oven, model PGB918SEMSS. It was purchased last year. The problem I am having is that the oven is very slow when cooking a turkey. Last year, a 13.5 pound turkey at 350 degrees took 5 and a half hours to cook and the meat by the bone was still red. I made sure the turkey was completely thawed before cooking. I cooked turkeys in my old oven I had before this in the exact same way without problems. The turkey was cooked in one of the disposable tins that you buy in a grocery store. I have made 3 turkeys so far using this oven and continually have the same problem that the oven is very slow when cooking a turkey. I also raised the cooking temperature but the turkey then becomes dry and have used the probe that came with the oven and that takes just as long. I also calibrated the oven 10 points but that didn't make a big difference. I would appreciate any comments or suggestions that anyone may have.
