Questoin about my refrigerator???

Thanks for all the comments. I checked to ensure the fridge was level. I ran if for several hours on propane with only 2 items in it (String cheese and a Lunchable). It got very cold using propane. I had to turn down the setting because frost was forming on the items. I switched it to the highest setting and over to electric that night and left it unopened for at least 9 hours. During that time it had warmed up inside quite a bit. I felt the cooling fins and they were not any colder that the temp inside the fridge.
