It has required some service over the decades. The old compressor had to be replaced after somewhere around 16 years, which was typical for old GE compressors. There were a couple of service calls to replace one or more of the internal fan motors and the there have been several service calls on the hot gas defrost system, the last one in the late 80s or early 90s. On the last service call, the GE tech told my mother that it was too old to fix and wanted to give her a certificate for a new GE. The bottom freezer design was no longer being made in 1977 when my parents decided to fix it rather than replace it. I was visiting in Florida and mom called so that I could talk with the serviceman. He went on about how if the defrost thermostat went out again, the part would probably be NLA. John and I had discussed the defrost system so I told him what John had told me: if the thermostat was NLA, we could bypass it by installing a timer to take it in and out of defrost. I also told him that we would not buy a new GE if we had to replace it. He agreed to fix it for mom. Fortunately, all of this was done when it was in my parents' home, It got a rest of about 11 hours on its trip up here. It is in my basement where it is still being used. I like the bottom freezer design much better than my newer GE with the top mount freezer in the kitchen, but it's not worth trying to move it upstairs.
