Drove 2 hours to a salvage yard in Akron, left with a new outlook on old compressors
I usually strip parts from newer units, never bothered with anything over 15 years old. But last Tuesday I needed a specific run capacitor for a 1989 Frigidaire and this yard had a whole row of crusty fridges. The owner, Bob, showed me a compressor from a 1972 model that still tested at 4.7 ohms across the windings. He said he's seen those old Tecumsehs outlast three replacement compressors in the same cabinet. That got me thinking, maybe I've been too quick to tell customers to just replace the whole unit when the hard part is still solid. I ended up pulling a few older motors just to practice rebuilding them this weekend. Any of you ever bother refurbishing pre-90s parts for fun, or is that just me?
Those old compressors might test fine cold but the windings and oil break down in ways a multimeter won't show you, and you'll be the one eating the callback when it dies in July. Bob's story about one Tecumseh outlasting three replacements ignores the hundred others that died like everything else.
