Is your RV refrigerator not cooling properly? Is it freezing your food? Do you have ice buildup that’s making a mess of things? These are possible signs your refrigerator is cooling inconsistently. If that’s the case, you might need to install an RV refrigerator fan to help it run more smoothly.

What Is an RV Refrigerator Fan?
An RV refrigerator fan is a device you can attach to your fridge’s fins or exterior vents to keep cold air circulating evenly or help the cooling unit out. When cold air circulates evenly, your fridge’s interior will stay at a consistent temperature throughout the appliance. Not only does the fan keep your food at safe temperatures, but it also helps your fridge run efficiently.

Why Do RV Fridges Need Fans?
For this article, we will primarily be focusing on propane / electric absorption style RV fridges, which are the most common type. All refrigerators are essentially heat pumps that move heat from inside the fridge to the outside, making the interior of the fridge cold. RV absorption fridges are special because they use heat to drive a chemical cycle that creates cold. It’s a bit counterintuitive, but it works well – as long as there is proper ventilation to get rid of the excess heat. This is where the RV refrigerator fan comes into play.
If a fridge is unable to get rid of its excess heat, it will run very inefficiently and likely not cool properly. A fridge that is not cold enough can be frustrating to deal with and is not safe for storing food. Adding an RV refrigerator fan can help improve this heat pump cycle.
What Does an RV Refrigerator Fan Do?
There are two main places where you can install an RV fridge fan and each has its own benefits.
Type 1: RV Fridge Fin Fan
Propane absorption style fridges typically use a set of fins that protrude inside the fridge. These fins absorb the heat from the air and get very cold. This first type of fan is installed inside the fridge box on the fins.

Most of the time, fins rely on natural convection air currents to cool the air, but this can cause a lot of problems. Without forced airflow from a fan, some areas of the fridge can get too cold, causing foods to freeze. Other areas may not cool enough (like on the door) and food can spoil. Also, without adequate airflow, ice can build up on the fins and make them much less efficient. Adding a fan kit to your fins keeps them defrosted.
Fans also distribute cold air better and make the fridge run more efficiently overall. Some RV refrigerator fans clip directly onto the fins in the fridge and some just circulate air. Both work, but the type that clips to the fins tends to offer better performance.
Type 2: RV Refrigerator Vent Fan (for Back of Fridge Space)
In addition to circulating cold air, it’s important to make sure the excess heat that the fridge is rejecting is being removed. You can always tell if an RV has an absorption fridge because it will have vents on the exterior wall or roof where the fridge is located to remove excess heat. Usually, they are designed to let cool air in at the bottom and vent hot air out at the top (higher on the wall or even out the roof).

Like with the fins, sometimes this natural convection does not work well and the fridge can get too hot. Especially on warm days or when the refrigerator-side of the RV is in the sun, heat can build up and the fridge will not cool properly. This is when a vent fan would be helpful.

The 6 Best RV Refrigerator Fans
Here are some of the best fridge fan options for improving your fridge’s airflow:
Type 1: Fin and Interior Fridge Fans
We used this fan kit for years and it worked great to keep our fins defrosted and our fridge running cool. However, you will need some electrical know-how to wire it into a 12-volt power source.

One alternative to wiring a fan to your fridge is to use a solar-powered fan to move the air. Usually, the sun is shining when your fridge is struggling the most. This is good news because a small solar panel can provide the power for the fan, keeping your fridge the perfect cool temperature even on the hottest days. Solar-powered fans work well with roof vent style fridges where the fan is mounted at the top with the solar panel.

Tips to Keep Your RV Refrigerator Working in Hot Weather
Hot weather is the most common challenge for RV refrigerators, so here are our top tips for keeping them cool:
First, you want to install an RV refrigerator fan to keep the cold air circulating. Second, park your RV so the fridge side is in the shade away from the sun. Third, run your RV fridge on propane. From our experience, most fridges will get colder and work more efficiently running on propane rather than electricity. And lastly, get a thermometer to track the temperatures inside your fridge and freezer. We recommend the AcuRite Refrigerator Thermometer below.
- Digital Thermometer | Includes one refrigerator thermometer and one freezer thermometer
- Easy to read display includes magnetic backing for fridge mount and keyhole for mounting on wall
- Audible Temperature Alarm | Get alerted to temperature spikes with customizable min and max range
- Each wireless thermometer includes clip for refrigerator shelf mount and suction cup for fridge wall
- Temperature Range: -40° to 100°F (-40° to 37°C); Wireless Range: 75 ft. (23 m)
Keeping an RV fridge cool when it’s hot outside can be quite a challenge and can even ruin your road trip if all of your food goes bad. But with a simple fan installation, you’ll never have to experience this frustration again. In truth, RV refrigerator fans are the one life-changing kitchen gadget you never knew you needed!

How has your conversion to the DC Compressor been working?
Well thats a long story, but we no longer have that fridge. It worked great initially but a year later started warming up. Turns out we had the first generation design and there was a flaw in the coolant routing that overloaded the compressor. They have since fixed the design and replaced all defective units. I know others that have installed it with great long term results. We were in a bind at the time needing a fridge so we installed a small residential fridge from home depot temporarily and discarded our old RV fridge 🙁 Since then we have replaced that fridge with a new DC model that Dometic just started offering, we have been running tests on it for them and so far it has been performing amazing.
While the Valterra product was designed for RV applications, we found it useful in a wine keeper where the temperatures were quite variable from top to bottom of the cabinet. This is durable plastic and should last a long time if properly cared for. Just as described and arrived as promised by the seller.
Good to know it worked for your wine fridge! Thanks for sharing your experience with the Valterra.
