Do you know why so many stoves in the Zone have the cosmetic portion of the door removed?

Here's what happens-Say a Zoner wants to make a pizza, turning on the oven to 400 is too complicated and will take too long.  Instead, the oven is turned to CLEAN.  20 minutes later the pizza is turning black, smoke is pouring out of the oven and cannot be opened.  Thus, the cover panel is ripped off in an attempt to open the door.
