What is a travel trailer refrigerator?

A travel trailer refrigerator is a cooling system that uses a absorption process to keep food cold while you are on the go. Travel trailer refrigerators work by using ammonia, water, and hydrogen gas to create a cooling effect. The travel trailer refrigerator is one of the most energy efficient ways to keep your food cold while traveling.

How does a travel trailer refrigerator work?

Travel trailer refrigerators work in a similar way to your home refrigerator, relying on a cooling system to keep food and drinks cold. The main difference is that travel trailer refrigerators run on either propane or battery power, rather than being plugged into an electrical outlet.

The cooling system in a travel trailer refrigerator consists of a number of metal fins that are cooled by a circulating gas. As the gas circulates, it picks up heat from the metal fins and carries it away. This process happens continuously, keeping the inside of the fridge cool and your food fresh.

What are the benefits of a travel trailer refrigerator?

While many people enjoy the benefits of owning a travel trailer, there are some downsides to this type of RV. One of the main complaints is that the refrigerator doesn’t work as well as a standard household refrigerator. In order to understand how a travel trailer refrigerator works, it is important to understand how a standard refrigerator works.

A travel trailer refrigerator uses a thermoelectric cooling system. This type of system uses electricity to cool the fridge down. The main advantage of this type of system is that it is very efficient and uses very little power. However, the main disadvantage is that it doesn’t work well in high temperatures.

If you are planning on using your travel trailer in hot weather, you might want to consider investing in a portable fridge. This type of fridge uses ice to keep food and drinks cold. While this type of fridge is more expensive than a thermoelectric cooling system, it will work better in hot weather.

How to choose the right travel trailer refrigerator?

Before you choose a travel trailer refrigerator, you need to decide what type of RV refrigerator you want. There are two main types of RV refrigerators: absorption and compressor. Each type has its own set of pros and cons that you should consider before making your decision.

Absorption refrigerators are the most common type of RV refrigerator. They are powered by LP gas, electricity, or both. Absorption refrigerators are very quiet and don’t produce any vibrations. They are also very lightweight, which makes them ideal for RVs that are towed behind a vehicle. However, absorption refrigerators can be more expensive to operate than compressor refrigerators.

Compressor refrigerators are less common in RVs, but they offer some advantages over absorption refrigerators. Compressor refrigerators are powered by electricity only, so they can be more expensive to operate than absorption refrigerators. However, they are much more efficient than absorption refrigerators and can cool your food more evenly.

What are the different types of travel trailer refrigerators?

There are three types of refrigerators that are commonly used in travel trailers: absorption, compressor, and 12-volt. Absorption refrigerators are the most popular type because they’re quiet and don’t require a lot of energy to operate. Compressor refrigerators are more expensive but they’re also more efficient. 12-volt refrigerators are the least expensive but they require a battery to run.

How to maintain your travel trailer refrigerator?

Your travel trailer refrigerator is a vital part of your RV—it keeps your food fresh, your drinks cold, and makes sure you have ice for those long summer road trips. But how does it work? And how do you properly maintain it to keep it running for years to come?

Here’s a quick guide to understanding how your travel trailer refrigerator works, as well as some tips on maintaining it.

Your travel trailer refrigerator likely uses one of two types of refrigeration systems: absorption or compressors.

An absorption fridge uses a process of evaporation and condensation to cool the air inside the fridge. This process is powered by either propane or electricity, making absorption fridges a great option for RVs that don’t have access to hookups.

Compressor fridges, on the other hand, use a compressor and Freon gas to cool the air inside the fridge. These types of fridges are more common in larger RVs and fifth wheels, and they run off electricity.

No matter what type of refrigeration system your RV uses, there are a few key maintenance tips you should keep in mind:
-Clean the coils: Dust and dirt can build up on the coils of your fridge, making it harder for them to do their job. Once a month, vacuum or brush the coils to remove any buildup.
-Check seals and gaskets: Make sure door seals are tight and gaskets are in good condition to prevent cool air from escaping.
-Defrost regularly: If you have an absorption fridge, you’ll need to defrost it every few months (depending on how often you use it). Compressor fridges typically don’t need to be defrosted.

Following these simple maintenance tips will help ensure that your travel trailer refrigerator runs efficiently for years to come!

Tips for using your travel trailer refrigerator

When you’re on the road, it’s important to have a good working knowledge of how your travel trailer refrigerator works. After all, this is one appliance that you really can’t do without. Here are a few tips to help you get the most out of your travel trailer refrigerator:

1. Make sure that your travel trailer is level before you turn on the refrigerator. If it’s not level, the fridge won’t work properly and your food could spoil.

2. When you first turn on the fridge, give it a few hours to reach its optimal temperature. Then, you can start adding food.

3. Be mindful of what you put in the fridge. Some items, like onions and garlic, emit strong odors that can permeate everything else in the fridge. So, if you want to keep your food from tasting like onions and garlic, store these items in a separate container or in the crisper drawer.

4. Don’t overstuff the fridge. This will make it harder for air to circulate and could lead to food spoilage.

5. Keep an eye on the temperature gauge and adjust as needed. The ideal temperature for a travel trailer fridge is between 35-40 degrees Fahrenheit.

By following these simple tips, you can ensure that your travel trailer refrigerator works properly and that your food stays fresh during your next road trip!

Troubleshooting your travel trailer refrigerator

If your travel trailer refrigerator isn’t working properly, there are a few things you can do to troubleshoot it. First, check to make sure that the fridge is turned on and that the power cord is plugged in. If the fridge is on and the power cord is plugged in, but the fridge still isn’t cooling, it’s possible that the cooling unit is not working correctly. To test this, open the fridge and feel the back wall. If it’s warm to the touch, then the cooling unit may need to be replaced.

Another possibility is that the fridge isn’t level. When a fridge isn’t level, the coolant can’t circulate properly and the fridge won’t be able to cool properly. To fix this, you can try adjusting the leveling jacks on your travel trailer.

If you’ve tried all of these troubleshooting tips and your travel trailer refrigerator still isn’t working properly, you may need to call a repairman.

FAQs about travel trailer refrigerators

Q: How does a travel trailer refrigerator work?
A: Most travel trailer refrigerators use either absorption or compressor cooling. Both types have their pros and cons, but absorption models are more common in RVs.

Q: What is the difference between absorption and compressor cooling?
A: Compressor cooling uses a refrigerant to cool the air inside the fridge. Absorption cooling relies on a chemical process to absorb heat from the air inside the fridge.

Q: Which type of travel trailer refrigerator is better?
A: That depends on your needs and preferences. Compressor models tend to be more expensive, but they’re also more efficient and better at regulating temperatures. Absorption models are cheaper, but they’re not as efficient and can be less reliable.

Q: Do I need a special RV refrigerator?
A: Not necessarily. You can use a regular household fridge in your RV, but it will use more energy and may not be as durable as an RV-specific model.


In conclusion, travel trailer refrigerators work by using absorption technology. This means that instead of using a compressor like a standard refrigerator, it uses a series of chemicals to cool the air inside the fridge. Ammonia, water, and hydrogen are the main ingredients used in this process. The chemicals are kept in separate compartments within the fridge and they work together to cool the air inside.
