ANSWER: This is a common complaint with RVers. The fact that your refrigerator is not getting cold enough while using electric could be an indication that there is a problem with the refrigerator itself, but before you go to the expense of taking your travel trailer in and having the fridge checked out there a couple of things you can try.
The problem could be that the cold air in your refrigerator is not getting circulated. Unlike home refrigerators most RV refrigerators do not come equipped with a circulation fan. There are battery operated RV Refrigerator Fan that can greatly improve the cooling efficiency of your RV's fridge. Installing a RV Fridge Vent Fan will also increase the efficency of the refrigerator.
I would also suggest that you perform some routine maintenance on your fridge. Watch the video below from RVing Expert Mark Polk for more great information on RV Refrigerators.
