I've got a Kenmore 110-96520100 electric dryer that is about 20 years old. Recently, it developed a problem that it wouldn't run unless you hold the start button in, upon releasing the button the dryer stops as well. I thought it was an issue with the button itself, but the switch appears ok. There is continuity when I push the button in and check with a meter. I've also checked the timer switch, door switch, thermal switch, both thermostats, and heating element (current one only a few months old). All have continuity and appear good.

I've also cleaned the vents thoroughly and nothing works. When you hold the button, it makes a sort of whirling sound and you soon begin to smell like burning plastic or wires and it shuts off whether the switch is depressed or not. I've read about other models needing a new control panel or relay to resolve this issue, but I don't think mine has these? I couldn't find anything like that on this model?

So, thoughts about how to fix? At this age, is it even worth continuing to fix problems or just get a new one? Thanks much

Thanks for the quick reply Scott. No, the belt is fine and the tub spins while it's running. So, I guess it's time to scrap it then?

Thanks again for responding Scott. From what I've been able to find, it looks like the motor will run somewhere in the $150 +/- range which is a fair amount towards a new dryer anyway. For years, it's taken running the loads twice to dry them anyway, so in the long run, we're probably saving money by getting a new one. That will make my wife happy I guess. Thanks for the input though.
