Removing your frig is not as big a problem as you may think. All doors need to come off, then remove the trim pieces that cover the screws on the mounting flanges. Remove all the screws from around the flange (12-15). Now for the outside stuff. Disconnect the 110 volt AC power supply (should be two, one for the frig and one for the ice maker). Disconnect the 12 volt power leads (two spade connectors, normally red and white in color). Disconnect the gas line with two wrenches, one for the flare nut and one to backup on the gas valve union.
Then unscrew the hold down screws (2-3) in the base of the frig on the outside floor ledge. Push on the back of the frig and make sure it is loose enough to move a couple of inches towards the inside of the coach. Now with two people, pull the frig out and place it on a good strong stool. Replace the ice maker line, clean all the coils and replace the fans (if so equiped). Check the vent in the roof for any foreign objects, Clean the chimney flu (per maintenance manual) and put the unit back in place.
