My folks bought a late 1950s Amana (I think) upright freezer when they got married in 1966. It was still running in 2011 when they had to move into a smaller house and got rid of it. It ran for at least 42 years with no issues.
Math is easier with caffeine. 52 years. Not 42.
I know a guy that has a 1957 pink refrigerator in his basement and it still runs. No fans or auto-defrost of course, but it looks practically brand new. Very quiet, too.
My folks built their home in 1948 and were gifted a Frigidaire fridge as a housewarming gift. It never died, but the door latch broke, and being so old, a replacement just wasn’t available. We bid our final goodbye in 1984. Thing was built like a WWII tank.
