Do RV refrigerators run on propane or electricity?
As we've already mentioned, even though propane powers the fridge, you still need an electrical source too. So either shore power, generator, or an inverter for the house batteries will be needed. Motorhomes, RVs, and travel trailers can also use a propane fridge.
How does an RV refrigerator work on gas or electric?
An RV refrigerator works by absorption and a chemical reaction between ammonia, water, and hydrogen. The ammonia is heated then goes through an evaporation and condensation process which causes the cooling effect of the fridge. The ammonia is heated either by a propane flame or electric element.

How Does an RV Refrigerator Work?
Even though the end result is the same as a standard 120V residential refrigerator (a box full of cold and/or frozen food), RV refrigerators don’t achieve that goal the same way. Your household refrigerator uses a compressor to run its cooling cycle, but a traditional RV refrigerator is different.
How is an RV Fridge Different from a Residential Fridge?
As we already described above, the biggest difference between an RV refrigerator and the model you’re used to in your sticks and bricks house is the fact that RV refrigerators use a different process for creating cold.
The Pros & Cons of an RV Refrigerator

What is an RV refrigerator?
When it comes to RVs you’ll see either compressor-driven refrigerators or absorption refrigerators. Absorption refrigerators tend to be most common. You’ll also see the term “residential-style refrigerator.” Unfortunately, this term can be confusing. Some RVers and RV manufacturers use that term to refer to the design, and others to mean a refrigerator that was designed for use in a fixed residence.
What type of refrigerator is used in RVs?
The most common type of refrigerator you’ll find in RVs is an absorption refrigerator . Absorption refrigerators can run off of LP gas. This makes them more flexible than compressor-driven refrigerators. A “2-way fridge” usually refers to an absorption RV refrigerator that can run off of AC Power and LP gas.
Why do you need a fan in a refrigerator?
Consider a fridge fan to circulate more air inside the fridge if you’re using an absorption fridge. This helps keep a more consistent temperature and can help maintain more even cooling.
How to help a refrigerator?
For any type of fridge, you generally want to help it by opening the door as little as possible. Try to limit the amount of time the fridge door is open.

What is the process of cooling a refrigerator?
The ammonia flows down from the condenser into a hydrogen-filled chamber called the evaporator. In this low-pressure chamber, the ammonia expands, cooling rapidly as it does. It is the evaporator that creates the cooling action of the refrigerator. A fan blows on the evaporator, cooling down the air as it blows past. This cold air is circulated through the refrigerator.
How does refrigeration work?
The refrigeration process starts with the generator, a vessel with water containing dissolved ammonia inside. A burner heats the generator until it reaches the boiling point of ammonia. Since ammonia boils at a lower temperature than water does, the ammonia leaves the generator and wafts up into the condenser.
What is a 12-volt RV refrigerator?
The 12-volt RV refrigerator mainly runs on 12-volt DC power from the internal battery of the rig (or possibly the starter battery of a car or truck). These refrigerators run on electricity only, not absorption or two-way RV refrigerators, which can burn propane to power their cooling system.
How 12 Volt RV refrigerators work: A simple answer
The 12 Volt RV Refrigerator can keep your food to the right temperature for storing, like your refrigerator that you use at home. Generally, it is small to fit the RV’s area and has some unique features, such as the ability to lock the door and run-on diverse power sources.

They also designed an RV fridge to deal with bumps on the road, characterized by latches and shelves to prevent the door from opening.
Is 12 Volt RV Refrigerator run on electricity or propane?
Its “dual fuel” choice is very suitable for RV campers. It means that while traveling, you can use the refrigerator and may not get electricity. When the electricity is more readily available and parked in the RV, the power source can transfer into continuous cooling.
How many amp hours does a refrigerator need?
When installing a residential refrigerator most RV manufacturers will come stock with four 6-volt batteries with 400 amp hours and 200 “usable” amp hours (because you should only drain standard lead acid batteries to 50%). Dealers and salespeople have told us “ you can run that fridge for days on these batteries ”.
Do refrigerators need inverters?
Cons: Most refrigerator manufacturers require a pure sine wave inverter. Inverter must always be left “on” to supply power. Inverters are not 100% efficient, so there will be some ‘lost’ power when inverting the power from 12v to 120v. Needs a lot of battery and solar power to compensate for the power draw.
