The older refrigerators did work well, but many of the '80s/90s ones didn't last much over 15 years or so, longer if they weren't used much. I'm told the worst thing for them is to be started and stopped frequently, it'll kill them sooner.
Water damage is definitely the biggest concern though. Floor, walls, and ceiling.
