Update...We have left the extreme heat of Arizona to the reasonable heat/higher humidity of Oregon for the next six weeks. I have replaced the thermistor, circuit board and heating element and have installed four fans on the back of the refrigerator and four inside the refrigerator and we still have considerable swings in temperature of the fridge from 28-42 degrees. The temperature really seems to go up when we open the fridge for only a matter of seconds. I am at a loss as to what to do next. I've tried everything I know to do and the fridge is only just over 2 years old. Any other ideas would be much appreciated.

My fridge is doing the same thing. I have a hard wired fan coming for the inside of the fridge and will be changing the thermistor to a different type that you can adjust to the desired temperature. These absorption type refrigerators struggle above 90* outside temperatures. Propane is a better choice to get maximum results out of the fridge vs running it on 120 side as in plugged into ground power.
As outside temps rise it is better to bring a cooler for drinks etc.and keep as little as possible in the fridge. At 100 degrees, these fridges will not maintain 38. Just returned from a week in Sierras and it was tough keeping it around 40.
Hope you saved the parts you replaced because i don't think any were defective. Also i use compressed air and blow air up the chimney to get rid of leaves or whatever may accumulate when the trailer sits. My unit does not vent through the roof so leaves are not an issue. My last rig did have that problem though. Also have you checked your gas flame? easy to remove the cover and see if there is any carbon blocking the holes in the flame pipe.
