We lost power in the receptacles in the door side slide of our 38FB all of the sudden.
I traced the problem to a plug in connector just inside the frame (you have to drop a belly panel to get to it). The plug had just bounced apart I guess.
Anyway, you can barely get your hand up there between the frame and the tank to reconnect it but it can be done. It had a snap when I put it back together but I put a tie wrap on it just in case.
Here is a picture. I may be the only one this happens to, but I thought I could save you some time if it does happen to someone else.
