I have a 2017 FB3820. Now my question is- what am I looking for? I just went out into the yard and put on the frig with shore power. Then turned on the front powervent. The frig fan, the light and the front display all stayed on, all seems good. Is this problem something that happens over time or right away. Or am I not looking at the right stuff? I'll check it out better tomorrow when I can see a little bit better, you guys got my all nervous now and got me running around in the dark
Thinking back, when I first bought my unit the circuit board in the powervent was no good- it would turn off for no reason. I replaced the board and it has been good ever since, but I wonder if this wiring issue had something to do with that failure.
