Bought this range based mainly on the LG rep and own other LG items. It takes an hour to bake a cake that should only take 30 minutes. I can turn the oven on to 350 degrees and when it signals the oven is up to temperature, I turn it off and immediately turn it back on to 350 and the oven is 330 degrees and shows heating up again. The only way I can bake is to increase the temperature by 20 degrees and pray.
