Mine is a 1202..
It has no window either.
I am wondering if I dare cut one in..
I am going to get some remote outdoor temp/humidity reading device.... Mine is so old it is made of wood.
Mine's the exact same thing lol. I'm going to just fill the water tray thing and run it for a while with my hygrometer in it. Then I'll just open the door real fast and see what it says and hope that it sticks to the same amount every time lol
