I'm stumped at this point, 2015 Keystone Passport 3320BH with dometic DM2652 refrigerator. Unit has worked fine until yesterday, most times it iis used for approximately 2-3 days per month. This trip has been nearly 2 months long, in AC mode while parked and auto switches to gas while traveling. Noticed on a stop yesterday while driving that the fridge status lights were not lit, waited until arriving at RV park to investigate and it appears as though there is no power, no power at all to upper control board, verified there is power to both 12v leads and 110v plug, verified power to lower control board for both 110 and 12v. 12v on both sides of thermo switch (with ring on it), all 3 fuses are good, pass continuity test and even bypassed with a jumper to verify. No power on pins that go to upper control board, no interior light. At this point I'm looking to replace control board but want to see if there is anything I'm missing.
