Dryer Shuts off and won't restart until cool
So I have a Kenmore 90 series dryer. I recently replaced all of the rollers because they were shot and one roller had completely fallen off. While I was in there I vacuumed all of the dust out of everything. After that repair my dryer will now sometimes stop mid cycle. After stopping, it will not restart for a while until it cools down. This also happens if I open the door mid cycle - it then will not restart until it cools down. I just took it apart again and tested the continuity on the 2 thermostats (one on the exhaust and one on the heating element area) when cold and when hot and they seem to be functioning correctly. I also checked the continuity on the 2 fuses (one next to each thermostat). The motor spins very smoothly and I got most of the dust out of it with the vacuum so I don’t think there is any added friction there. What is my next step to diagnose this dryer? I’m thinking maybe it’s the motor overheating - how would I figure out if that is the issue? Any help would be greatly appreciated. Thank you!
