I have the same problem, it was bowing when room temp is cold, but it changed when i turn my heater on... U just need to use it your self to believe it.
I think the metal on the door is too thin which caused this problem, or could be the plastic... :confused:
Hard to explan... but the door seems shut pretty tight than before.
It's so weird, the door seems to expand (out of shape) and shrink (shuts tight) depends on the room temp condition... :confused:
