Amana Model ABB2222FEB2
I tried to follow your original post, but I don't seems to have the same parts as you describe. I couldn't find a wiring diagram for my model number, but I did take off the back freezer panel (interior) and everything was frozen. I defrosted the coils and cleaned things up, but I can't find a defrost timer, to see if that was the problem. I took off the back panel (exterior) and couldn't find anything there.
So...can you help point me in any direction??? I'm pretty good at solving things, but not if there not there. Is this one of the refrigerators operated electronically that you mentioned?
