Cold drinks and fresh food on the road? Sign me up.
Your RV Refrigerator’s cool refreshments allow your camper to feel at home, but it’s not always up to snuff.
Too many trips have turned sour after reaching into your RV fridge only to find the temperature isn’t where you’d like it to be.
If your fridge is not cooling correctly, or you are experiencing ice build-up and freezing temperatures, it’s a good sign you need to call in some backup.
Luckily, you don’t have to dial up your local repair shop just yet. Instead, a simple solution could give your refrigerator the boost it needs to keep your drinks cold: An RV refrigerator fan.
RV refrigerator fans are installations that help evenly circulate the cold air produced by your fridge, relieving some pressure on your central cooling unit and keeping every corner of your RV refrigerator cool through hot summer days.
Don’t let rotten lettuce spoil your next summer vacation. We researched every aspect of RV fridge fans so you can save some power and propane while keeping your food fresh.
What Is an RV Refrigerator Fan?
An RV refrigerator fan is an extra installation that helps keep fridges at a steady temperature in high heat. The fan is nothing more than a small device attached to your refrigerator’s fins or exterior vents that grabs onto the cold air and spreads it evenly across your RV fridge.
There are several different types of RV refrigerator fans and various locations you can install your fan depending on where your refrigerator needs back up.
No matter where you hook up your fan, as long as you connect it to a power source, it will boost your fridge’s ability to maintain a steady, cool temperature.
We’ll explore all the different places you can hook up your fan so you can personalize your plan for fridge relief.
Why Do RV Fridges Need Fans?
Take everything you think you know about refrigeration and throw it out the window.
RV refrigerators don’t work like a fridge in your home. Instead of relying on electric compressors, RV fridges work on a heat absorption system.
An absorption refrigerator absorbs heat from inside the fridge using ammonia and sodium chromate.
These chemicals collect the warmer air and pass through a condenser unit, typically located in your refrigerator’s fin.
Inside this condenser unit, the warm air and ammonia combine with hydrogen gas, which jumpstarts the air particle’s natural evaporation process.
The cooling you feel inside of your fridge is a result of this evaporation. Without a fan, the ammonia struggles to move throughout the entire space on the inside of your fridge.
Hot temperatures magnify the ammonia’s struggles. When the weather outside reaches 100 degrees, the heat will creep through your fridge too fast to be adequately absorbed.
RV fridges need fans to step up when the heat is on. By circulating cool air around the fridge’s exterior or helping the ammonia and cool airflow throughout the interior, a fridge fan will keep your food cool through extreme weather.
What Does an RV Refrigerator Fan Do?
Depending on where you need help, there are two types of RV fridge fans, each set up in different places with different strengths and weaknesses.
RV Fridge Fin Fan
You should install This type of RV refrigerator fan inside your fridge, as close as possible to the cold fins inside the unit.
In an absorption camper fridge, the cold fins are the source of the cool air that keeps temperatures down for the entire fridge.
An RV fridge fin fan will boost the radius that these fins can propel cool air.
The fridge fin fan takes the cool air from the fin and spreads it further out than the fins can do on their own.
As a result, the fan’s airflow helps prevent icy build-ups and dead spaces caused by the cool air all staying in one place.
If you are experiencing areas of your fridge that are too cold while also having areas of your fridge that never cool down, hooking up an RV fridge fin fan will better distribute that cold air and make your fridge work smarter instead of harder.
RV Refrigerator Cooling Exhaust Fan
The other main style of RV refrigerator fan works on the exterior of your fridge.
Your RV fridge likely has vents in the back that draw cool air in and blow hot air outside of your vehicle. You can usually find these vents on the outside wall or roof close to your fridge.
On a scorching day, or whenever the fridge side of your RV is in the sun, the natural flow of air through these vents won’t get the job done.
Hooking up an RV refrigerator vent fan kick starts air circulation by bringing more cool air and getting warm air out faster.
Vent fans installed in the middle of your cooling unit’s backside will force more airflow through your RV fridge’s outside vents and cool everything off from the outside.
Fridge owners who can’t get the temperatures to stay down no matter the power source should look towards the exterior for solutions and set up a refrigerator vent fan.

Tips to Keep Your RV Refrigerator Working in Hot Weather
Hooking up an RV refrigerator fan will go a long way towards providing you with endless cool beverages, but that doesn’t mean your job is done.
We’ll lay out a few strategies employed by veteran RVers that go a long way towards keeping temperatures down no matter how hot it is outside.
Give your fridge and fridge fan a better chance to succeed with these simple tips and tricks.
Turn your fridge on 24 hours early
Give your fridge a head start and allow it to cool off for a full day before you start filling up.
An empty fridge will cool off more efficiently, and some RV refrigerators may struggle to cool down at all if they are full of food before you fire up the propane.
Use Propane to Cool
Propane gas will cool your fridge faster than using 12V power. While either method will work efficiently to maintain cool temperatures, try to initially power your refrigerator on propane energy sources to reach the coldest possible temperature.
Pro Tip: Modern RV fridges will generally work on both 12 V and propane gas. Depending on your specific system, you can use a combination of the two to most effectively power up your fridge.
Use propane in the initial 24 hour period your fridge is warming up to get it to optimal temperatures, and once you hit the road, you can switch over to 12 V to get the most cooling out of your resources.
Organize your fridge
The longer you stand and stare through your refrigerator door, the harder your fridge will have to work to reach baseline cool.
Organize your fridge before you leave the driveway, so you will always know exactly where everything is inside your fridge.
Once you know everything inside your fridge, you can map out your dinner and understand precisely where you need to go to pull out everything you need efficiently.
Closing your door just a few seconds earlier will help heaps of cool air stay where it needs to be.
Park in the shade
The backside of your fridge has little insulation protecting it from the harsh glare of the summer sun.
In the middle of a hot day, make sure the side of your car that houses the refrigerator is receiving direct shade.
Sunlight beating down on your ventilation system will make it practically impossible for your refrigerator to function properly.
Check the Seals
Don’t comb over all the inner mechanics of your fridge before first checking the sealant between the fridge door and your RV.
Air sneakily leaking out of tiny cracks and crevices in your seal will cancel out the efforts of even the best RV fridge fans.
Run your fingers along the entire outside edge of your refrigerator door slowly, feeling along for any surprising cold air.
A sealant issue is an easy fix.
Your fridge manufacturer will have a new seal built to fit your fridge ready for order, and you’ll need a pair of pliers.
Remove the old seal with your pliers and apply the new protection by lining up the frame and putting pressure along the edges.
Use a Thermometer
It’s essential to keep on top of your refrigerator’s performance. A thermometer will allow you to understand your fridge’s average baseline temperature. If you notice the temperature begin to creep up, you can fix the problem before it leads to spoiled milk.
There aren’t many RV refrigerators that couldn’t use the help of a RV refrigerator fan on a hot day.
If you are experiencing a troubled unit or just want to find a way to boost the performance of your fridge, RV refrigerator fans are affordable options that provide quality relief.
In addition to being affordable, RV owners can install most of the fans on our list in an hour or less, so your RV refrigerator can be ready for desert heat before the weekend.
