We have a 2024 Crossroads Hampton, floorplan 372FDB. This fall will be the first time will be the first time we'll winterize a camper. It has a Samsung residential refrigerator model RF18A5101SR which has a SPACE Compact Icemaker. We would appreciate advice on how to winterize the icemaker. On line searches talk about a possible button on the bottom or front that allows the antifreeze to flow into the icemaker. We don’t see one. FWIW, we have located the water line to the refrigerator with shut off valve under the kitchen sink. Thanks in advance for any help anyone can offer!
