So I just replaced the door gasket on this stove and the upper right corner is not getting a tight seal (that would be the corner above the handle that opens the door. It is just slightly leaking and I can barely see flames looking through the gasket, and doesn't pass the dollar bill test. I put a square piece of metal across the front face of the stove and I do not think it is warped. Any advice? is it possible to increase the closing tension or something like that?
