Best Frost-Free Refs Ever Built
Really did not come about till the 80s through the late 90s, during this time period build quality and the quality of materials improved greatly.
Also as efficiency improved compressors no longer run so hot or have to work as hard, this has really improved longevity, we hardly ever see bad compressors any longer with the exception of a few brands and bad model compressors.
It is true that many refs today have gotten so complicated and gadget laden that fewer of today's really fancy refs will last as long as the 80s - 90s models, but then look at how heavily built refs like this Frigidaire were and how few survived, I have no dough that we will see many of the current complex refs going strong in 30-40 years from now.
