Ahhh, the wonderful RV camper refrigerator – you either love them or have a very rocky relationship with them. Ask ten RVers what their thoughts are on RV fridges, and you’ll get ten different answers. So why are they such a mystery?
How do RV refrigerators work
Most RV refrigerators use a different cooling method than the standard fridge you have at home. RV fridges operate using gas absorption, which involves heating ammonia to magically cool the refrigerator. Unlike your fridge at home, there are no moving parts in an RV refrigerator – things happen by heating the cooling unit either with propane or an electric heating element, depending on what source you use.
So what’s this mean to the RV traveler? Well, when they work, they work. However, when things aren’t working quite right (or not at all) it can be a mystery to pinpoint the exact problem. Keep that in mind and make sure things are up to snuff before hitting the road. We’re here to be your camper refrigerator guide!
Camper refrigerator types
There are four types of RV refrigerators:
- compressor refrigerator
- absorption refrigerator
- residential refrigerator
- hybrid camper refrigerator
Compressor fridges rely on AC/DC power. So, when you’re plugged in at your campsite, shore power keeps them running. While you’re on the road or boondocking, you’ll have to count on your RV batteries to keep them powered.
There are two types of absorption refrigerators for RVs:
- 2-way RV refrigerator
- 3-way RV refrigerator
Most RVs will have this type of camper refrigerator.
2 way RV refrigerator
2-way RV refrigerators can run off AC power (from shore power or a generator) or LP gas.
3 way RV refrigerator
3-way RV refrigerators can run off AC power, DC power, or LP gas. Because of this, they are one of the most flexible of the camper refrigerator options.
With both 2-way and 3-way fridges, you can save power by switching to gas. This means you can stay unplugged for longer. However, they often don’t cool as quickly or as evenly. Luckily, we have tips to help with that!
Residential-style refrigerators are typically less expensive, cool more evenly, and have a greater storage capacity. But, they can only run off of shore power. To keep them running while your RV is not plugged in, you’ll need an RV inverter or generator.
Hybrid camper refrigerator
This type of RV fridge is a combination of an absorption and compression fridge. Hybrid fridges, like this Dometic RV refrigerator, give you the best of both technologies.
RV refrigerator alternatives
Additionally, a lot of RVers choose to bring along a chest-type portable refrigerator that works more like your home fridge. These compressor-based chests operate on 12 or 120 volts and are extremely efficient. The downside? You’ll need to have lots of battery life (or solar, or plan to run your generator) if you plan on doing any long-term boondocking with one of these.
Still, they are a fantastic option if you have space. Once you’ve got the fridge all figured out, these five smart solutions will help you optimize your RV kitchen space too.
Where to find the best RV refrigerators
There are a lot of options when it comes to putting a refrigerator in an RV and even more places to shop for them.
To help narrow it down, two of the most popular brands to look into for your motorhome or travel trailer refrigerator are:
Dometic RV refrigerator
The Dometic Super Hybrid Refrigerator boasts its use of compressor and absorption technology. Absorption powers the fridge while the compressor powers the freezer.
Dometic has varying types and sizes of RV refrigerators, as well as air conditioner units and more to fit your RV needs!
Norcold RV refrigerator
The Norcold N1090 is a compression model, 12-Volt refrigerator. With a night mode setting, it promotes less energy consumption and reduced noise. Norcold also offers smaller fridge options for those with less space.
Tips to keep your camper refrigerator running
Now that you’ve found the best fridge for your rig, here are some tips to help you get the most out of that RV refrigerator.
1. Don’t pack it completely full
RV fridges work best when they have some empty space for air to circulate. To help out, consider using a small battery-operated fan to cool things more evenly inside the fridge.
2. Make sure your RV refrigerator is level
RV refrigerators need to be level to operate. Since there is magic gas absorption stuff happening, the unit needs to be level so that the gas can properly flow through the cooling unit. What’s this mean? Don’t park on a steep incline where things are seriously out of level – this can cause permanent (and expensive) damage to the fridge. When you are traveling, the magic juice inside the cooling units sloshes around, so you don’t have to worry about staying level while going down the road. It’s when you are parked when things can go wrong.
3. Pre-cool or buy cold drinks before putting them in the fridge
It can take some time for an RV fridge to get to the proper cooling temperature, so you can keep the temp from fluctuating by putting in already cold beverages.
4. Park your RV in the shade when it’s hot
RV fridges respond to the weather outside. Seriously! If it’s boiling hot outside, your fridge will most likely have a little jump in temperature. Conversely, if you are camping in cold temps, you might need to raise the temperature of your fridge. If it’s super hot outside, try to park your rig in the shade on the fridge side. This helps to keep your refrigerator operating efficiently.
5. Turn it on ahead of time
Since they can take a while to cool, turn your camper refrigerator on a day before you plan to leave or stock it with food.
6. Check the refrigerator roof vent
If the vent carrying warm air away from the fridge is clogged with debris, it can cause the unit to work inefficiently or not at all.
7. Install a 12-volt fan.
Sometimes installing a small fan to help draft the warm air away from the fridge does wonders. They can be purchased online and installed by you or an RV dealership. Note: This is not the same fan that helps circulate air inside the fridge.
These seven tips can keep your fridge cool and running smoothly.
EXTRA TIP: If you are questioning whether or not your unit is running properly, purchase a cheap thermometer. The normal temperature for a fridge is below 40° F. Monitoring this will ensure that your food is staying at a temperature that prevents spoiling and harmful bacteria from growing.
Keep your cool
Don’t let melted ice cream ruin your trip! Keep your drinks cold and ice cream frozen with a good refrigerator in your RV.
