Best RV Refrigerator Fans to Keep Your Food Cold

Fridge fans

RV refrigerators are fabulous! They keep perishable foods fresh and safe and beverages cold. But what happens when your produce starts to freeze and your drinks get warm? Unless you delight in the traveling lettuce popsicle, you might consider an RV refrigerator fan.

What Is an RV Refrigerator Fan? 

RV fridges are usually absorption refrigerators that heat an ammonia solution that removes heat from the refrigerator box. They don’t perform well in extreme heat or if you open the fridge door too frequently. 

The refrigerator coil is against the exterior wall of your RV, so when temperatures outside that wall rise, your refrigerator struggles to maintain an optimal temperature. Adding a fan to your RV refrigerator can distribute cool air inside the box and create an even temperature throughout the fridge.

These fans operate on 12V DC power, and you can easily connect them to an interior fridge light where they’ll draw power. Alternatively, you can connect to fridge’s rear power supply, but you’ll need to add an on/off switch in this case.

Where Does an RV Refrigerator Fan Go?

There are a couple of suitable placements for an RV refrigerator fan. One is behind the refrigerator, where the fan (or fans) can remove excess heat through the exterior vent. 

You could also place an auxiliary fan on the refrigerator’s inside, either on or near the cold fins. The fan circulates the air evenly to achieve a consistent temperature throughout the refrigerator. 

Why You Need an RV Refrigerator Fan

RV absorption fridges work pretty well in moderate temperatures, but they only cool to a certain degree below ambient temperatures. If you’re camping or traveling in a location where the temps are running high, your fridge will struggle to reach 40 degrees below the ambient temperature. At 90 degrees F, you’re looking at 50 degrees inside your fridge. You’ll be throwing food away if it reaches 100 degrees.

An auxiliary RV refrigerator fan can either remove excess heat or evenly distribute cool air throughout the refrigerator, helping your fridge run more efficiently, saving power and propane.

Reviewers note that the operating sound is “quiet, like computer fans”. They’re also impressed with this triple-fan unit’s efficiency.

Tips for Keeping Your RV Refrigerator Cold

Along with installing an RV refrigerator fan to keep the cold air circulating, try to park the fridge-side of your RV in the shade. 

Also, consider running your fridge on propane when possible, as most fridges get colder and work more efficiently when running in propane mode. 

Finally, use a digital thermometer to monitor your refrigerator and freezer’s internal temperatures. 

Overall, installing an RV refrigerator fan can make all the difference in keeping your refrigerator evenly cold and running efficiently, saving you the danger and expense of spoiled food and frozen lettuce!
