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.

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.
Thanks for the tip. I did try inverting my fridge but only let it sit for a few hours. I will pull fridge tonight and try again this time for 24 hours. I will let you know how it goes.
