10-Minute Tech: Cool Fridge

Last year, after arriving in Arizona in September, we discovered that our RV’s refrigerator was struggling to stay cool with outside temperatures averaging in the 90s. I made a shade to keep direct sunlight from baking the outside of the unit. I took some scrap ¾-inch plywood and made two simple wood brackets (pictured below) that I spray-painted black to protect them from the weather. These brackets are removable and fit at the top of the slideout.

I then used vinyl material to make the shade, and put wood strips at the top and bottom to add weight so it doesn’t blow around. It was easy to make and install, and the best part is that it works as designed. I left a lot of clearance between the slideout and the material to allow for airflow, plus ventilation for the refrigerator’s inlet and exhaust vents.

Black bracket made of plywoodI also use a couple of ropes at the bottom that I stake down for extra protection in case the wind kicks up. When not in use, the shade rolls up easily to be stored, and I can set it up and take it down in minutes.

  1. We live in Arizona, and my husband installed fans to keep our refrigerator cooler. He placed them so that they pull air in from the side and push the air up over the coils. 6-inch computer fans work great.

  2. I added the fan to move air, and it made a huge difference. The fan is temp controlled, and I hear it ramp up when in the sun. This shade is a great idea to add as well.
