It’s siliconed into a finished wall so I can’t easily get behind it and I can’t find any numbers whatsoever on the inside or the door. It’s very old. Any ideas where some useful numbers might be located? It looks close to this one: http://forums.atari.io/uploads/monthly_01_2017/post-1-0-85941700-1484503314.jpg. It’s 26" wide if that helps.
I solved my own problem but I thought it might be useful to put the answer here. I found the model # listed at the bottom of the unit, covered up by a trim piece. On the front, underneath the door. I’ll probably put up another post about the actual problem I’m having.
