"Probably the item that has given me the best service, the most bang for the buck, as they say, is my Kenmore dryer. My in-laws bought a washer and dryer when my wife was born in 1969. They gave them to us not long after we got married, probably about 1991. When my wife got pregnant in 1996, she demanded a new washer because the wig-wag needed to be replaced about once a year ($15, 15 minute fix that I could do in my sleep). Can't have a baby and be without a washer for a day, right? So I bought a washer. Just a washer. Dryer worked fine. I replaced that washer a couple of years ago with one of the new high efficiency machines. Dryer worked fine. Dryer still works fine. Every couple of years, I pull it out from the wall, remove the back, and clean all the lint out of it. Next time I do that, I will probably replace the belt, which looks original. I'm guessing my father-in-law paid around $100 for it 47 years ago. I can afford to throw a belt at it."
Astonishing that we have virtually identical stories. We bought a Kenmore electric dryer in 1968 (probably exactly like yours), and it has been with us ever since, and through at least 8 moves. I have managed to keep it running as it is very simple to work on. For the most part, all it has ever needed was a couple of belt replacements, about a 10 minute job, and a door switch replacement. Around 8 years ago I did have to replace the electric motor, which cost me, I think, about $80 for a replacement motor, and was a simple job. I was happy to pay that. About two years ago, the thermostat went out. No big deal, I thought, until I tried to find a replacement, or even a substitute. Nobody had one, not even Sears nor any of the big appliance parts dealers on the internet. As a last resort, I looked on eBay, and there it was. It's still running today, and my wife has frequently said that she has no interest in getting a new dryer until this one just cannot be repaired any longer. It is a part of the family. BTW, we are now on our fourth washing machine since we bought that Kenmore dryer. The last one, also a Kenmore, was 26 years old when it died last year.
