Had a Kenmore electric drier in the house when we moved in 19 years ago, and it was not new then. It was working fine when we got rid of it last year (neighbor gave us an almost new Maytag Neptune front load washer and gas drier). I had replaced the timer once years ago and the thermostat switch once too. The lint screen broke, got one off e-bay for like $8. Got rid of it last year when our neighbor gave us her almost new gas drier (and a washer).
I love the gas drier, clothing dries quickly and costs a lot less to operate than electric driers. The washer, not so crazy about (moldy gasket issue, just like most front load washers).
