Came with the house (built 2005). I'm sure I can find a model number on it if that's useful. I suspected the temp was off as recipes always needed longer cooking times. Got an oven thermometer and was surprised. Digital display shows 450 degrees while thermometer shows about 360. To get a temp of 425 I needed to set it to 530.

I really have no idea what to look for or check. And I'm not sure if its worth calling a repair guy... I wonder if this is one of those cases where I can get a new one for not much more, and sell this one in classifieds (it does work... before I started baking breads I wouldn't have known and couldn't have cared so I'm sure someone else will want it).

Thanks.
