Replacing an RV fridge is a job you can do yourself if you have basic tools, though the work involves disconnecting propane, water, and electrical lines before you slide the old unit out

Most RV refrigerators are held in place by a frame that bolts to the cabinet, not permanently built in. You will need to turn off propane at the tank, drain any water lines, disconnect the 12-volt DC power, and sometimes remove trim panels or cabinet doors to access the bolts. The actual removal takes two to four hours for someone doing it for the first time. Reinstalling a new fridge follows the same steps in reverse, though you should have the model number of your RV and your current fridge before you order a replacement — sizes and connection types vary widely.

The job is straightforward if you follow the safety steps in order: propane off first, then electrical power, then disconnect lines, then unbolt. Rushing or skipping steps is where people run into trouble. If you are not comfortable working with propane or electrical systems, a mobile RV technician can handle the whole replacement for $300 to $800 depending on your location.

Key Takeaways

  • You must shut off propane at the tank before you disconnect any gas lines, and you should not attempt to relight a propane fridge without professional help if you are unsure about the procedure.
  • RV fridges come in different sizes and connection types, so measure your cabinet opening and check whether your current fridge uses propane, 12-volt DC, or both before ordering a replacement.
  • Most RV refrigerators can be removed by unbolting the frame from inside the cabinet, though some models require you to remove trim panels or cabinet doors first.
  • If you are not comfortable working with propane lines or electrical systems, a mobile RV technician can handle the replacement for $300 to $800 depending on your location and fridge type.

Gather your tools and check your current fridge specifications

Before you start, you need to know what you are removing and what you are putting in. Look at the fridge door or the back panel for a model number and manufacturer name — common brands in RVs are Dometic, Norcold, and Absorption. Write down the model number and the dimensions of the fridge itself (width, height, depth). Then measure the cabinet opening where the fridge sits, because the opening is often slightly larger than the fridge.

Gather a socket set, adjustable wrench, screwdrivers (both Phillips and flathead), a flashlight, and a bucket or towel for any water that drains when you disconnect the water line. If your RV has a basement or exterior compartment where the fridge vents, you may need to access it from outside — check your owner's manual or look under the RV to see where the vent is located. Have a pen and paper ready to sketch where each wire and line connects, because you will need to reconnect them the same way on the new fridge.

Turn off propane and electrical power before disconnecting anything

Propane is the most dangerous part of this job. Walk to your propane tank — usually located in a compartment on the exterior of the RV — and turn the valve clockwise until it stops. This shuts off gas to the entire RV. Wait five minutes to let any remaining gas in the lines dissipate.

Next, turn off the 12-volt DC power. Go to your RV's main electrical panel (usually inside a cabinet near the driver's seat or in the bedroom) and flip the switch labeled "12V" or "DC" to the off position. If your RV has a battery disconnect switch, flip that as well. Do not skip this step — a live 12-volt circuit can cause a spark when you disconnect wires, which is dangerous near propane.

Disconnect water, propane, and electrical lines in the right order

Open the cabinet doors or remove trim panels to access the back of the fridge. You will see three types of connections: a water line (usually a small plastic tube), a propane line (a thin copper or steel tube), and one or two electrical connectors (wires or a plug).

Start with the water line. Place a bucket underneath and gently pull the tube off the fitting. A small amount of water may drip out. Next, disconnect the propane line by turning the fitting counterclockwise with your wrench — turn slowly and stop if you hear a hiss (that means gas is still in the line, so wait longer). Once the propane line is free, cap it with a small plastic or metal cap to keep debris out. Finally, unplug the electrical connectors or disconnect the wires by loosening the terminal screws. Take a photo of the wire connections before you disconnect them so you know which wire goes where on the new fridge.

Remove the old fridge by unbolting the frame

The fridge frame is usually bolted to the cabinet at four points — two on top and two on the bottom, or sometimes along the sides. Look inside the cabinet on both sides of the fridge and you will see bolts or screws. Use your socket set or wrench to remove these bolts. You may need to reach behind the fridge or work from inside the cabinet, so the flashlight is helpful here.

Once all bolts are removed, carefully slide the fridge toward you. It is heavier than it looks — ask someone to help you support the weight as you pull it out. If the fridge does not slide easily, check that you have removed all bolts and that no water line or wire is still connected. Once the old fridge is out, set it aside and clean out the cabinet opening with a vacuum and damp cloth.

Install the new fridge and reconnect all lines

Slide the new fridge into the cabinet opening, making sure it sits level and flush with the cabinet edges. Bolt it in place using the same holes as the old fridge — if the new fridge has bolt holes in different locations, you may need to drill new holes or use shims to make it fit. Check that the fridge door opens and closes smoothly without hitting the cabinet.

Reconnect the water line first by pushing the plastic tube onto the fitting until it clicks or sits snugly. Reconnect the propane line by threading the fitting clockwise — use your wrench to tighten it, but do not over-tighten or you will crack the fitting. Reconnect the electrical wires by matching them to your photo: usually red to positive, black to negative, and any other color to ground. If your new fridge has a plug instead of loose wires, straightforward plug it in.

Once all connections are made, turn the propane back on at the tank by turning the valve counterclockwise. Turn the 12-volt DC power back on at your electrical panel. Wait a few minutes, then check that the fridge is cooling. If you smell propane, turn everything off when ready and call an RV technician — do not attempt to fix a gas leak yourself.

Test the fridge and troubleshoot common problems

After the fridge is running, let it cool for at least two hours before you put food inside. Check that cold air is flowing from the vents and that the temperature dial or digital display is working. If the fridge is not cooling, the most common causes are a kinked water line (which blocks the cooling cycle), a loose electrical connection, or a propane line that is not fully tightened.

If the fridge cools on 12-volt power but not on propane, the propane line may not be fully connected or the igniter may need adjustment — this is a job for an RV technician. If the fridge does not cool on either power source, check that the 12-volt DC power is actually on by testing another 12-volt device (like a light) in your RV. If nothing on 12-volt power is working, you may have a blown fuse or a dead battery, which is a separate issue from the fridge installation.

When to hire a professional instead

If you are not comfortable working with propane lines, or if your RV fridge uses a sealed propane system that requires special tools to disconnect, hire a mobile RV technician to do the replacement. Most technicians charge between $300 and $800 depending on your location, the fridge model, and whether they need to order parts. Call ahead and ask whether the price includes the new fridge or just the labor — some shops sell the fridge and install it as a package, while others install a fridge you buy elsewhere.

You should also hire a professional if your RV has a built-in fridge that is glued or welded to the cabinet, or if the cabinet opening is a non-standard size. A technician can modify the cabinet or source a custom fridge, which is faster than trying to make a standard fridge fit. A professional can also handle the propane system safely if you have any doubts about your ability to reconnect it correctly.

Frequently Asked Questions

How long does it take to replace an RV fridge?

Removal usually takes one to two hours, and reinstallation takes another one to two hours. If you run into complications — like a stuck bolt or a water line that is hard to access — add another hour. Most people finish the whole job in a single afternoon.

Can I replace my RV fridge with a standard kitchen refrigerator?

No. Standard refrigerators need 120-volt AC power and do not work on 12-volt DC or propane. RV fridges are designed to run on multiple power sources and to stay level while the RV is moving. A standard fridge will not cool properly in an RV and may be a fire hazard.

What if I cannot find the model number of my old fridge?

Measure the cabinet opening and the fridge itself, then call an RV parts supplier with those measurements. They can tell you which fridges fit your space. You can also take a photo of the fridge and show it to a technician, who may recognize the model by sight.

Do I need to refill the water line after I reconnect it?

Most RV fridges have a small water tank that you fill manually — check your new fridge's manual for the location and capacity. Some fridges do not have a water line at all and cool using only propane and 12-volt power, so confirm what your new model needs before you assume you have to add water.

What should I do with my old RV fridge?

RV fridges contain refrigerant and other materials that need proper disposal. Contact your local hazardous waste facility or an RV salvage yard to find out where to take it. Some RV shops will take your old fridge when you buy a new one from them.
