JD1923:
I should clarify my issue. We have a Dometic 3 way RM2454 refigerator. Out charger/inverter is a Xantrex Freedom XC 3000 Pro Inverter.
So the situation was: After the 3rd day of camping, we left the campground to go to the fair and was gone 4 hours.
Upon getting back to the trailer, the refigerator was off completely. I tried turning the unit on and it would not start up on AC. I then switched it on DC and the Xantrex started up (likely to charge the batteries) and did ot turn off. Since it is under my wife's bed, I know the noise would be too much for her. I then switched it to propane and it ran fine. The next day after I thought about it for awhile, I pushed the auto switch in and out for a few times, as it would not activate the first time and only run on propane. After working the Auto switch a couple of time it finally worked and switched to AC.
So the moral of the story is.:
1. I think that one of us had accidently hit the on/off switch before leaving the trailer. The auto swtich had not been pushed for a couple of years, so the contacts may have been dirty.
2. I have always found the button operation to be difficult to get it to ingage, maybe due to dirty contacts. That would explain difficulity in getting the refig started again and switching to AC.
3. After discussing the siuation with a knowledgable friend, he suggested buying a new eyebrow board from Dinosaur Electronics who make a better board the Dometic, which I have ordered. I also ordered a new Dometic board (which includes the face plate) since the cost was less than $5.00. I will now have 2 back up boards when needed.
Other explalination would be appreciated.
