Keystone Premier Bullet, fridge woes!

2014 19 footer, with an Atwood HE-0801 refrigerator. Supposed to be the gold standard of models, able to automatically switch from AC to gas. Trouble is, we experienced a reverse polarity episode...don't ask how! 😕

All other systems are fine, plugged in or on the batteries. The fridge, though, does not work...on gas or AC. My two red 40 amp fuses were both blown, so I replaced them, thinking I got lucky, but the fridge is still not operational. The control panel, interestingly, seems fine and reads like everything is in order. 

I'm afraid my control panel is fried. Is that it behind the black box in this picture? Is there another fuse, or a reset button, that I may have missed?

Initial research fears the control may not be available to replace. ☹️
