What's up with the fridge?

I posted a question here about changing out to a residential fridge and running it off an inverter while traveling. My fridge is over 13 years old and would not cool below 42 degrees. We ran it on electric most of the time because the burner would make a popping noise when it was on gas. Well, as a last ditch effort, Wednesday I took it to a local repair shop and had the burner replaced. I figured it was just throwing away $200 bucks. Picked it up Wednesday night and took it home with the fridge running. It is sitting in my driveway in full sun, 95 degrees outside. When I got home yesterday afternoon I went in to check the temp. Wow, 32 degrees inside the fridge. Should I dare hope that was the problem. I am thinking now that maybe the heating element on the electric side is not working correctly as well, thus new burner = better heat. You can barely hear the new burner, the old one was very loud. The tech also ask who did my recall. He said the wiring was just threw in there "willy nilly" (his term). He said he redid the wiring for the recall and did it like it was supposed to be. DW and I were talking last night, the fridge really has not worked properly since we had the recall completed. Mayby the tech that did the recall did not hook the fans back up. Maybe something there, who knows. We are heading out tonight for four days on the river in MO. I have my fingers crossed.
