RV refrigerators fail for predictable reasons, and replacement costs and timelines depend on which type you have and whether you can install it yourself

An RV refrigerator that stops cooling usually means one of three things: the cooling unit has failed, the propane system that powers it is broken, or the electrical circuit is damaged. Some failures are fixable without replacement — a blocked vent, a tripped circuit breaker, or a propane line that needs bleeding. But if the cooling unit itself has failed, you are looking at replacement. The cost ranges from $400 to $2,500 depending on size and type, and the timeline depends on whether you can do the work yourself or need to hire someone.

Key Takeaways

  • RV refrigerators come in three main types — absorption (propane/electric), compressor (12-volt DC), and compressor (120-volt AC) — and the type you have determines what you can replace it with.
  • Absorption units are the most common in travel trailers and motorhomes but are the most expensive to replace; compressor units are more efficient but require more electrical power.
  • Measuring your fridge opening and checking your RV's available power (propane supply, 12-volt capacity, or 120-volt shore power) before shopping prevents buying a unit that will not fit or work.
  • Professional installation at an RV service center typically costs $200 to $600 in labor, while DIY installation is possible if you are comfortable with basic plumbing, electrical, and propane connections.
  • Used and refurbished RV refrigerators are available through salvage yards and online marketplaces and can cost 40 to 60 percent less than new units.

The three types of RV refrigerators and how they differ

An absorption refrigerator cools using propane or 120-volt AC power (or both). It has no moving parts in the cooling system — instead, a heating element boils ammonia in a sealed loop, and the evaporation cools the interior. These are standard in most travel trailers and Class A motorhomes because they run quietly and work while you are driving on propane. They are also the most expensive to replace, typically $800 to $2,500 new, because they are larger and the cooling unit itself is pricey.

A compressor refrigerator works like a household fridge — a motor compresses refrigerant to create cooling. RV compressor units come in two versions: 12-volt DC models that run off your RV battery, and 120-volt AC models that run off shore power or a generator. Compressor fridges are more efficient and hold temperature better in hot weather, but they draw significant power. A 12-volt compressor can drain your battery in hours if you are not plugged in; a 120-volt model requires shore power or a large generator. New compressor units cost $400 to $1,200.

The type you have is usually determined by what your RV was built with. Replacing an absorption fridge with a compressor model is possible but requires rewiring and sometimes additional battery or power infrastructure, so most owners replace like with like.

Measuring your space and checking what will fit

RV refrigerator openings are not standard. Before you shop, measure the height, width, and depth of your current fridge opening in inches, and note whether the opening is flush with the wall or recessed. Take a photo of the space with a tape measure visible. Manufacturers list dimensions for their units, but a fridge that is 1 inch too tall or too deep will not fit, and you cannot return it once you have removed the old one.

Check whether your RV has a vent above or behind the fridge. Absorption fridges need airflow to the outside to dissipate heat; if your opening does not have a vent, you cannot install an absorption model. Compressor fridges do not need an external vent but do need good air circulation inside the RV to prevent overheating. If your current fridge has a vent, you will need to keep it or install a new one if you switch to a different type.

Write down the model number of your current fridge if you can find it — usually on a sticker inside the fridge or on the back. Knowing the brand and model helps you understand what power sources your RV is set up for and whether replacement parts are available if you choose a refurbished unit.

Checking your RV's power supply before you buy

If you are replacing with an absorption fridge, confirm that your RV has a working propane system. Check your propane gauge, listen for the hiss of propane at the connection, and make sure the propane line from the tank to the fridge is not kinked or damaged. If you are replacing with a 12-volt compressor, check your battery capacity — most RV batteries are 100 to 200 amp-hours, and a compressor fridge draws 5 to 10 amps continuously, which means it will drain a fully charged battery in 10 to 40 hours of use without recharging. If you are replacing with a 120-volt compressor, you need reliable shore power or a generator large enough to run it (usually 3,000 watts or more).

Many RV owners use a hybrid approach: an absorption fridge that runs on propane while traveling and on 120-volt AC when plugged in. If that is your current setup, replacing with the same type preserves your flexibility. If you are moving to a compressor model, you are committing to either battery power (12-volt) or shore power (120-volt), which changes how you can use your RV.

New versus used and refurbished units

A new RV refrigerator from a manufacturer like Dometic, Norcold, or Vitrifrigo costs $800 to $2,500 for an absorption unit and $400 to $1,200 for a compressor unit. These come with a warranty (usually 1 to 3 years) and are may provide to work, but the cost is high.

Used and refurbished units are available through RV salvage yards, online marketplaces like eBay and Facebook Marketplace, and specialty RV parts retailers. A used absorption fridge in working condition typically costs $300 to $800; a refurbished unit (cleaned, tested, and sometimes with a limited warranty) costs $400 to $1,000. The risk is that you cannot test it before you buy, and if it fails after installation, you have no recourse. Some salvage yards offer a 30-day return window if the fridge fails, so ask before you buy.

If you choose a used or refurbished unit, ask the seller for the model number and year, and research whether parts are still available. Older absorption fridges can be difficult to repair if something breaks, because manufacturers discontinue parts after 10 to 15 years.

DIY installation versus professional service

Installing an RV refrigerator yourself requires disconnecting the old unit (which involves shutting off propane, draining water lines, and disconnecting electrical), removing it from the opening, and installing the new one in reverse. If the new fridge is the same model as the old one, the connections usually line up. If it is a different model or type, you may need to adapt propane lines, water lines, or electrical connections.

The work is doable if you are comfortable with basic plumbing (connecting water inlet and drain lines), electrical (connecting 12-volt and 120-volt circuits), and propane (connecting and bleeding propane lines). You will need a wrench set, a screwdriver set, a level, and possibly a propane wrench. The job typically takes 2 to 4 hours if everything lines up, or longer if you need to adapt connections.

Professional installation at an RV service center costs $200 to $600 in labor, depending on how much adaptation is needed. The service center also handles propane testing and electrical inspection, which gives you confidence that the fridge is safe and will work. If you are not confident in your skills, or if the new fridge requires significant rewiring or plumbing changes, professional installation is worth the cost.

Where to buy and what to compare

New RV refrigerators are sold through RV dealerships, RV parts retailers (like Camping World and Amazon), and direct from manufacturers. Prices vary by retailer, so call or check online before you buy. Some retailers offer installation services; others sell the unit only and you arrange installation separately.

When comparing units, look at the cooling capacity (measured in BTU for absorption fridges, or in cubic feet for compressor fridges), the power source (propane, 12-volt, 120-volt, or hybrid), and the warranty. Read reviews from other RV owners on forums like iRV2 and RV Forum to see how long units typically last and what problems are common.

Ask the retailer about return policy and warranty coverage. Some retailers offer a 30-day return window if you change your mind; others do not. Manufacturer warranties typically cover the cooling unit but not installation labor or damage from improper installation.

Frequently Asked Questions

Can I replace an absorption fridge with a compressor fridge?

Yes, but it requires rewiring your RV's electrical system and possibly upgrading your battery or shore power capacity. A 12-volt compressor needs a large battery bank; a 120-volt compressor needs reliable shore power or a generator. The cost of upgrading power infrastructure can exceed the cost of the fridge itself, so most owners replace like with like.

How long does an RV refrigerator usually last?

Absorption fridges typically last 10 to 15 years with regular maintenance. Compressor fridges last 8 to 12 years. Lifespan depends on how often you use the RV, how well you maintain the cooling system, and whether you keep the fridge level while traveling.

What should I do if my fridge stops cooling but is not broken?

Check the propane supply (if absorption), the battery voltage (if 12-volt compressor), and the circuit breaker or fuse. Clean the vent and coils, and make sure the fridge is level — absorption fridges do not cool well if tilted. If those steps do not work, the cooling unit may have failed and replacement is likely necessary.

Can I install a fridge that is slightly larger than my opening?

No. RV openings are tight, and forcing a fridge that does not fit can damage the cabinet, the fridge, or both. Measure carefully and stick to units that fit your opening exactly. If no unit fits, you may need to modify the opening, which is a job for a professional.

Do I need to turn off propane before I remove the old fridge?

Yes. Always shut off the propane supply at the tank before disconnecting any propane lines. If you smell propane after disconnecting, do not ignite anything — open windows and doors, and call your RV service center or a propane technician.
