Hello, I've tested my oven and know that it runs 10 degrees too hot. My problem is that once I put something in there, the temperature can drop dramatically, depending on how much I put in; however, it doesn't come back to the set temperature in a few minutes. It drops and very slowly climbs back up, but then I have to open the door to rotate my pans and it drops again. By the time I am supposed to take my baked goods out, the oven has still not come back up to temperature. It seems to be struggling to keep up. So when I bake at 350°, I am actually never baking at that temperature, but a much lower one. Is this normal? If not, can I fix it? Really appreciate everyone's input! Thanks.
