Easy tips to make sure your RV’s fridge stays cool all summer long


By Gail Marsh
If it’s not already, it’s going to get hot pretty soon, and your RV refrigerator is going to need your help!

Here are some tips for keeping your RV fridge cooling effectively all summer long:

  • Check the seals located all along the edge of the refrigerator and/or freezer doors. If you notice cracking, loose seals, or even places where the seals are missing, make repairs before you head to the campground. An easy way to check seals that show no visible signs of compromise is take a piece of paper about the size of a dollar bill (or just use a dollar bill!). Place the paper into the open freezer door and then close the door. When you gently tug on the paper, you should feel some resistance. That means the rubber is sealing properly. Test with the paper or dollar bill all around every side of the door(s).
  • Also, check the outside refrigerator vent. Clear out any debris, wasp, or bird nests that may impede air circulation.
  • Consider purchasing a digital remote thermometer like this one. This will enable you to check the inside temps of both the fridge and freezer without having to open the doors – letting all that nice cold air escape. (This is especially important if you have health medications that must be stored at a specified temp.)
  • Purchase a fridge fan to keep inside. It will evenly circulate the air and help your refrigerator run more efficiently.
  • Turn on your RV refrigerator 12-24 hours before you leave home. This will give the unit a head start in cooling by using propane. Stock the shelves in the fridge with foods and condiments that are already cooled. These items will aid in cooling the fridge interior.
  • Do not overfill the refrigerator. It needs adequate airflow around items in order to keep foods consistently cooled.
  • Load the freezer with foods that are already frozen. (I like to bring made-ahead meals when we camp for several weeks, but I always freeze the meals in our home freezer before placing them inside the RV freezer.)
  • When you are ready to travel, switch to your 12-volt DC power. (Gas cools your fridge down most effectively, but electricity is more efficient in keeping it cold. Plus, you won’t have to worry about using propane while driving.)
  • Consider buying ice rather than adding that extra stress on your RV refrigerator’s ice maker – especially when it’s really hot outside.
  • When possible, park your rig so that the refrigerator side is in the shade to assist with cooling. (Here’s a trick on doing that!) Also, make sure the RV is as level as possible. Your fridge may not operate properly if your rig is too far off-level.
  • Always cool down leftovers to room temperature before placing them inside the fridge.
  • Know what you want to remove from your freezer or fridge before you open the door. It will help keep the inside air temps cool/cold.
  • Defrost your freezer when ice builds up. To do this, put frozen foods inside a cooler to keep them frozen. You can put a pan of hot water inside the freezer, close the door and wait for the ice to melt. Some folks like to use a hairdryer on a low heat setting because it’s quicker.

I line my freezer with those cheap plastic cutting boards cut down to size. Then, when it comes time to defrost I just remove the liners and empty the ice into the sink. No need to use a hair dryer or a bowl of warm water. Also, it only takes a couple of minutes so you don’t have to transfer your food into an ice chest.

I think you got the wrong link for the remote temp displays. Your link goes to a digital display that goes inside the fridge (note the hooks to hang on a fridge rack.

Great idea though. I use remote displays on my home fridge since the genii at Whirlpool decided we only need to know what the temp is set too, and not the actual!

Here’s a great deal

And Amazons Choice This looks like mine. Works great but more money.

I put frozen jug of water in freezer and ref to help cool it off then when it’s cooled l put in supplies. plus we use a bag of ice of our drinks which help keep freezer cold. Gallon jug go back in freezer at home

Gas cools your fridge down most effectively, but electricity is more efficient in keeping it cold . . .” What? Who says? By what logic?

Yeah. That needs some explanation. Also, our fridge is propane or 110 AC, so the comment about switching to 12 volt DC is moot. I truly WISH we had a 12 volt DC fridge, and if we did there certainly would be no propane attached to it.

In 40 years of RVing, my experience has been that on really hot days when the fridge is struggling to keep temperatures down on electricity, I switch to propane and find it works better.
