We bought a used RV (propane) refrigerator which had stood unused for quite awhile. We couldn't get it to keep cold. When we were about to give up on it, a friend told us how to fix it. RV refrigerators use an ammonia coolant that has a kind of oil in it. After they are not used for awhile, the oil separates out. He helped my husband invert the refrigerator (stood it on its top) for 24 hours. Then they righted it, lit it, and within hours we had ice cubes in the freezer compartment! It saved us from buying a whole new fridge. He said it doesn't always work, but it's always worth a try.
Outstanding! Thank you! I just bought a 1977 trailer and I haven't tried the fridge yet, but now I at least have an option if it doesn't work.
