New oven burns the tops of my loaves
I've been baking sourdoughs using dutch ovens for about 5 years now. I recently replaced my old electric oven with a new LG electric oven model LREL6323S, When I use conventional bake it burns the tops of my loaves with the upper heating element. I called them and they said that their oven uses both top and bottom heating elements to improve the uniformity of the heat. I disagree with them there. The upper element is exposed, therefore the heat is radiation heat rather than conduction/convection heat. They also say there is no turning off this feature.
I'm looking for a standard electric home oven. There must be a way to bake where the broiler element does not come on. I'd like to spend no more than 1000 USD. It would be nice to get more than a basic bottom-of-the-line oven. Thanks.
