Skid, the proper thing to do , as we learned here , is to throw more money at it .... a couple thousand and she'll be right as rain , or you could purchase about 34 Tons of Ice , with that amount ... That should keep your food cool till the end of the world , next year ...
A enlightened few have chosen to replace them entirely ... with more conventional refrigerators ... Those few still standing in line waiting to shove their Absorption reefers up their RV dealers nether regions ...

How old is your frig?
Next thing is how level is the frig when operating?
Do you have a fan inside the box as well?

You say it rises in temperature when you travel. I take it you may be operating it in the LP gas mode during this time. Have you tried operating it in electric when traveling? If it still does not cool and all controls, venting and air seals are good, the only other thing it can be is the cooling unit. You may have flaked sodium chromate causing a restriction in the system. A new or rebuilt cooling unit would be needed. Or change it to residential style ref.

rv is a 94

I added anoter fan outside last night
Ambient temp dropped and was about 60 last night and I tried it on gas and the fridge this morning was 60 and freezer was cold as normal could it be a plugged chimney I am doubting it since freezer cold and fridge not.

tried a fan on the inside last year moved air so much the door stuff warm so I removed it. and worked and cooled fine

Rv is pretty level I would think if it is not level enough then freezer would not work I hat to buy a 500 replacement but I need to now if I am going to use it the next time I have planned.

The deciding factor for us was the amount of time we are not plugged or able to run on the inverter or generator. Even on it's best day when working "properly" our fridge was not what we called good enough. Not to mention much smaller that a residential type fridge that fit in the same space.

We can run easily on the inverter when the rig is running without worrying about killing the batteries. The generator if somewhere it won't bother anyone and needed and as long as we leave the doors closed can sit for hours unplugged depending on temperatures.

So considering the few nights we spend without being connected to power the decision was easy. Ditch the RV fridge and get a household one.

I wish it was that easy on ditching it

We boondock all the time and have only stayed at three campgrounds ever. And battery life and genset running time is crucial

We boondock in the winter and stay for 4 days straight at -25f I think the residential type is out of the question I wish I could trust me

The Amish units are highly regarded - wish we had bought ours from them, even though ours is apparently working just fine - but the Amish units I've seen pictured and describe sure do look nice.

For what it's worth, when ours failed, the freezer section was the last to stop working properly, long after the refrigerator section stopped cooling properly - just the way the RV refrigerators work I guess...
