It has 12.8 volts to the board coming in as well as the same voltage from the upper board to the lower. All the pinpoint voltages from the manual are as they should be per Dometic manuals. When it stops cooling on AC after the 14-16 hour range (and 5 full days on my last test??) The freezer will have defrosted and temps climbing above 50+ or higher and yet the stack will be warm as well as the element (not hot like it is when it actually working). It almost seems to me (and maybe it's not reasonable) that on 120 only, that after it initially cools down or runs for x amount of time, that it overheats and trips something and never calls for cooling again...But if the fridge is totally shut down or ran on LP for a several hours, days, or whatever, I can turn it on, or swap back to 120 and it will work again for 14-16 ish hours and then not cool again.
