Getting a camper fridge to work is not as simple as plugging it in and turning it on. There are several factors to consider, from the type of fridge to the power source, and even the temperature outside your camper van.
Firstly, it's important to know the different types of camper fridges available: absorption, thermoelectric, and compressor fridges. Absorption fridges are popular as they are almost silent, but they require proper ventilation and can be expensive to run on propane. Compressor fridges are energy-efficient and can keep food frozen, but they can be noisy. Thermoelectric fridges are durable and great for rugged terrain, but their cooling ability depends on the ambient temperature.
When it comes to power, camper fridges typically use a combination of propane and electricity, giving owners the flexibility to use their fridge while travelling or parked without electricity. However, some fridges only run on electricity, which can be limiting.
To get the most out of your camper fridge, there are several tips to consider: allow at least 6 hours for it to cool down, start with cold items inside, don't overload the fridge, and keep the doors shut to maintain the temperature. It's also important to keep the fridge level and ensure proper ventilation to avoid spoiling food and damaging the appliance.
By understanding the different types of camper fridges, their power requirements, and optimal usage, you can ensure your camper fridge works effectively to keep your food and beverages cold during your travels.
What You'll Learn
The different types of camper fridges
There are three main types of camper fridges: compressor fridges, absorption fridges, and thermoelectric coolboxes. Each type has its own advantages and disadvantages, so the best choice for your camper will depend on your specific needs and preferences.
Compressor fridges are the most common type of campervan fridge and are known for their high cooling efficiency. They use a compressor and refrigerant to quickly reach and maintain desired temperatures, even in hot climates. They offer precise dual-zone temperature control and are energy-efficient, drawing less power than other options. This makes them suitable for running on your campervan's battery. However, they tend to be more expensive and heavier than other options, and some people may find them noisy.
Absorption fridges, on the other hand, operate silently and can run on various power sources such as propane, 12V DC, and 120V AC. They have no moving parts, which contributes to their durability and longevity. However, they take longer to cool down and may struggle in high ambient temperatures. They can also draw more power than compressor fridges, especially when running on 12V DC.
Thermoelectric coolboxes are lightweight and portable, making them suitable for shorter trips or day outings. They are typically more affordable than compressor and absorption fridges, and are easy to use, but they have limited cooling capacity and efficiency. Their effectiveness depends on the surrounding temperature, so they may not be suitable for extended journeys or hot climates.
When choosing a camper fridge, it's important to consider factors such as size, power consumption, temperature control, durability, and portability. You should also take into account your budget, the number of people you're travelling with, and the duration of your trips.

How to optimise a camper fridge's performance
Camper fridges are a convenient addition to your camper van kitchen setup and are not too costly. Modern camping coolers and fridges are designed for efficiency, so now you have the information to get the most out of your camping fridge. Here are some tips on how to optimise a camper fridge's performance:
Choose the Right Type of Fridge
There are three different types of fridges available: absorption, thermoelectric, and compressor fridges. They all have their pros and cons and are excellent options for camper vans, motorhomes, and cars.
Absorption fridges are almost entirely silent and use propane or electricity. They are a good option if you want to conserve electricity from your camper's battery. However, they require proper ventilation and the cost of propane can add up.
Compressor fridges are energy-efficient and can keep your food cold even on the hottest days. Most models allow you to freeze food, but they can be a little loud at times.
Thermoelectric fridges are durable and tough, with fewer moving parts. They have the option to cool or heat food and drinks, making them a good choice for winter camping. However, they rely on the ambient temperature to cool down, so they may not be ideal for hot climates.
Set the Correct Temperature
Keeping your refrigerator set to the correct temperature will prevent food from spoiling. The Food and Drug Administration (FDA) states that your fridge should be at or below 40° F (4.4° C). However, a camper van fridge temperature should be between 35 to 38 degrees Fahrenheit (1.7 to 3.3° C) to account for fluctuating temperatures in the camper.
Pack Your Fridge Strategically
Place all frozen goods near the middle-bottom of the fridge, as this will keep them colder for longer and allow the frozen air to move upward, cooling the rest of your food and drinks. Separate drinks from food to prevent soggy items, and keep meat near the bottom of the fridge as it is often the least used food.
Install the Fridge in a Shaded, Level Part of the Camper
Secure the fridge in a shaded area of the camper, away from direct sunlight, to prevent the fridge from working harder than necessary. Use maple or oak boards to brace the fridge and keep it level, especially if you have an absorption fridge, as uneven surfaces can cause improper cooling and spoiled food.
Keep the Fridge Cold
To get your camping fridge colder, lower the thermostat settings. You can also add a few frozen items, such as ice-cold milk or frozen water bottles, to help bring down the temperature.
If you have a thermoelectric fridge, keep its surroundings cold by using air conditioning and fans, and consider using a roof vent to pull hot air out of the camper.
Maintain the Fridge Regularly
Keep the fridge clean and well-maintained. Check the seals regularly and clean and replace them as needed. Remove the refrigerator cover and blow it out with an air hose once a year to get rid of dust and cobwebs.
Choose the Right Size
Consider the capacity of the fridge and choose one that suits your needs. Think about the number of people you will be catering for and the duration of your trips.
Pick a Reputable Brand
There are a few companies that specialise in RV fridges, including RecPro, Norcold, and Dometic. Most RV forums agree that these brands offer quality products, so you can't go wrong with any of them.

How to care for your camper fridge
A camper fridge is a handy appliance to keep your food and beverages cold while camping. Here are some tips to help you care for and maintain your camper fridge:
Choose the Right Type of Fridge
There are three main types of camper fridges: absorption, thermoelectric, and compressor fridges. Absorption fridges use propane or electricity and are known for being silent. Compressor fridges are energy-efficient and can keep your food cold even on hot days. Thermoelectric fridges are durable and less affected by movement, but their cooling ability depends on the ambient temperature. Choose the type that best suits your needs.
Optimal Temperature Settings
Set your camper fridge to the correct temperature to prevent food spoilage. The ideal temperature range for a camper fridge is between 35 to 38 degrees Fahrenheit (1.7 to 3.3 degrees Celsius). This is lower than the recommended refrigerator temperature of 40 degrees Fahrenheit (4.4 degrees Celsius) by the Food and Drug Administration (FDA) to compensate for fluctuating temperatures in your camper.
Proper Packing
When packing your camper fridge, place frozen goods at the bottom-middle, separate drinks from food to prevent sogginess, and keep meat near the bottom. This arrangement optimises cooling and helps prevent food from spoiling too quickly.
Installation and Ventilation
Install your camper fridge in a shaded and level part of your camper to ensure optimal performance. Keep the area around the fridge well-ventilated to prevent overheating. Regularly check and clear any obstructions from the vents, such as leaves, dirt, or debris.
Maintenance and Cleaning
Keep your camper fridge clean and well-maintained. Check and clean the seals regularly to prevent cool air from escaping. Once a year, remove the refrigerator cover and use an air hose to blow out any dust, cobwebs, or debris that may have accumulated.
Power Options
Camper fridges can run on different power sources, including electricity (AC and DC) and propane. If using propane, ensure proper ventilation to avoid any health risks. If your fridge has a 12-volt (battery) electric option, be cautious when dry camping or stopping for extended periods, as it may drain your battery.

The power sources for camper fridges
Camper fridges are a convenient addition to any camper van, RV, or motorhome setup, and there are a few options when it comes to powering them. The power source you choose will depend on your specific needs, preferences, and budget. Here are the most common power sources for camper fridges:
Propane
Propane is a popular power source for camper fridges, especially for those who want to conserve electricity for other appliances. It is a good alternative to electric power, as it doesn't rely on battery power. Absorption fridges commonly use propane, but they can also use AC and DC electricity. However, it's important to ensure proper ventilation when using propane to avoid any health risks. Additionally, propane can be more expensive in the long run compared to other power sources.
Electricity
Electricity is another option for powering camper fridges. Standard home refrigerators use a compressor to cool quickly, but RV refrigerators typically run on gravity and a different cooling system. Camper fridges can be powered by a 12-volt DC battery, 110-volt AC power, or a combination of both. Some modern camper fridges also have the option to run on 120-volt AC power, which can be convenient if you have access to an electrical outlet during your travels. However, this may not be practical if you plan to camp off-grid or in remote locations without access to electricity.
Portable Power Stations
Portable power stations, also known as solar generators, have become a popular choice for powering camper fridges. These stations are compact and efficient, providing a reliable power source for various electronic devices and appliances. They are designed to supply electricity for devices that require DC power, such as car fridges. One of the main advantages of using a portable power station is the flexibility it offers. You can use your camper fridge outside of your vehicle, such as during picnics or when setting up a portable kitchen at your campsite. Additionally, power stations operate silently, creating a more peaceful outdoor experience.
Combination Power Sources
Some camper fridges offer combination power sources, allowing you to switch between electricity and propane. This can be advantageous depending on your specific needs and circumstances. For example, if you're boondocking or dry camping without access to electrical hookups, you can use propane to power your fridge. On the other hand, if you're camping with access to electricity, you can switch to electric power to conserve propane. Combination power sources give you the flexibility to choose the most suitable and cost-effective option for your trip.

How to install a camper fridge
Installing a camper fridge is a big project that requires careful preparation and, ideally, more than one person. Here is a step-by-step guide on how to install a camper fridge:
Step 1: Measure Everything Twice
Before purchasing a new fridge, measure the space in your camper to ensure the new appliance will fit. Check that the space is tall, wide, and deep enough, and that the refrigerator door can open fully without hitting anything. Remember that split doors require less clearance. Also, make sure your camper has an inverter, and if not, install one.
Step 2: Uninstall Any Existing Refrigerator
If there is a current refrigerator in place, it will need to be removed. Start by turning off the propane at the main valve and disconnecting the line from the back of the refrigerator. Install a "Propane Terminator" and release the 12-volt electrical wires, capping them with wire nuts. Remove any screws or fasteners holding the refrigerator in place and take it out.
Step 3: Secure the New Refrigerator or Find Help
Residential refrigerators can be very awkward to handle, so it is best to get help from another person. If you are working alone, secure the refrigerator to a heavy-duty hand cart with ratchet straps to prevent it from getting loose and causing an accident.
Step 4: Slide the New Refrigerator Into Place
If there is no exterior access hatch, you may need to plug the new refrigerator into a 120-volt socket before sliding it into place. Use fasteners, such as self-tapping sheet metal screws, to secure the refrigerator and prevent it from rocking during travel.
Step 5: Powering the New Refrigerator
For a new residential refrigerator, you will need at least a 2000-watt inverter, preferably Pure Sine. Your battery bank needs enough power to keep the inverter running and the refrigerator cool. Consider including a solar kit to keep the batteries charged when off-grid.
Step 6: Finishing Touches
Cap the propane line from the old unit—ensure that propane and power lines are handled by a qualified person. Put in a new, waterproofed platform for the new fridge to sit on, ensuring it can't leak onto any components below. Maneuver the new unit into place and plug it in for 24 hours to ensure everything is working properly.

Frequently asked questions
Camper fridges use a combination of propane or electricity so they can run in different situations. They don't use a compressor like a standard home fridge. Camper fridges use a power source to heat up the fridge, with a combination of water, ammonia, and hydrogen gas inside. The chemical reaction causes evaporation, which cools the refrigerator.
There are three main types of camper fridges: absorption refrigerators, compressor refrigerators, and residential refrigerators. Absorption fridges are the most common and use evaporation and condensation caused by chemical reactions to keep cool. They can run on AC power, propane, and sometimes DC power. Compressor fridges are faster and more efficient but can't run on propane. Residential fridges are compressor fridges designed for home use and can only run on AC power.
It's important to pack your camper fridge strategically to prevent food from spoiling and to stop the fridge from warming up too quickly. Put frozen goods in the middle-bottom of the fridge, drinks and food separately to prevent sogginess, and meat near the bottom of the fridge.
