Hi I have a Kenmore dryer 400S. A couple of months ago, it quit working midcycle. I vacuumed it out, checked the door switch, replaced the motor, replaced the timer switch, replaced the heating element, and replaced all four fuses. It does the same thing: it activates the heating element but the motor doesn’t run. I’ve rechecked the motor install four times so I know it is in there correctly, and I replaced the fuses twice just to make sure I didn’t get a faulty one. The only thing left is the wiring… but I’m hoping there is a simpler answer that I somehow missed. Can someone give me some advice on what to do at this point? Update (03/06/2017) I should mention that I installed the dryer motor, checked it, then installed the thermal fuse. At this point the dryer ran again (so I knew the motor, fuses, timer switch, and power worked). Then it shut off after thirty minutes- same as the first time when I first began to replace items. So here I replaced all four fuses. It ran again for thirty minutes. Then it quit. So I changed the heating element and four fuses (again). It didn’t run again. Now I turn the timer switch to timed heat and the element activates but no motor- like when the problem started. If it didn’t keep working, I’d worry about my fuse box (which I checked) or the power cord or any number of parts. However, it seems to reset with new fuses but then quits again.
Have you checked the voltage and polarity at the wall? If you’ve lost one line of 120v at the outlet it will cause this problem. You should have 120v on one line and 120v on the other line. Across both you need 220v.
Have you checked the belt is installed correctly, and deactivates the belt switch? Also, here is a good troubleshooting guide. It’s for a Samsung dryer, but the principles will be the same for yours: https://m.youtube.com/watch?v=MNv1AEW-3U…
