2017 37MDQS, my GFI is located in the bathroom. I noticed the outside fridge was not working. Re-set the GFI in the bathroom and solved the problem. Not sure where your GFI/GFI's are located but most likely the problem.
I used to wire houses as a side job. Have had more than a few GFI's bad new out of the box.
