Hello again, Ever since I started this Harman, the door glass gets dirty after about 24 hours. It's always in the same place. The rest of the glass stays perfectly clean. Is this because of a leaking door gasket, or glass gasket? The door feels like it has a tight seal when I close it. Below is a picture of the problem. It's the dirty spot on lower to middle right of the door glass. Thanks for any input. It cleans easily in just a few minutes, but for what I paid for this stove, I don't think I should be having this problem this early on. Thanks.
