Oh I got it! Motor runs but heating element is not running! So when slide said Kill power and restore power that didn’t refer to hitting the push on button on the dryer but actually plugging in the machine?
I think Samurai had mentioned that scenario earlier where occasionally a customer has a dryer that tumbles with no heat – might be that one of the 2 pole breakers was tripped. In this case its more than flipping the pole breaker on, you are literally disconnecting it from the heating element and only running the appliance on 120 volts literally.
