Shut off the propane valve to the refrigerator outside the RV. Refrigerators in RVs run on three power sources: propane (for when the engine is off and the RV is not connected to electric hook-ups), a 110-volt feed and a 12-volt feed.
Unplug the 110-volt feed and the 12-volt feed from the back of the refrigerator. Disconnect the propane line that runs into the refrigerator's regulator by pulling it out. It is also located behind the refrigerator.
Unscrew the screws holding the refrigerator to the bottom of the closet it rests in. Unscrew the molding from the frame around the face of the refrigerator. These screws keep it from bouncing or sliding around when the RV is in motion.
Slide the refrigerator out of the closet and remove it from the RV. This is where it can become challenging; if the refrigerator does not fit through the main door of your RV, you will have to remove one of the windows to get it out. Removal of these windows is not an easy task. If you cannot remove a window, you may need to remove the steering wheel from the steering column and take the refrigerator out the driver's-side door.
Slide the new refrigerator into the closet. Screw it back into the floor and screw the molding back to the frame of the closet.
Connect the propane line, the 110-volt feed and the 12-volt feed to the refrigerator.
