Samsung dryer issue

Model Number: DV395ETPARA/A1
Brand: Samsung
Age: 1-5 years

my dryer is running about 5 mins then displays a number 1 not the display then a min later cuts off and displays HE I have done research and found that most people say it's the thermistor or thermostat I tested both and they checked out ok I even went ahead and tried to replace them with new ones same exact issue (I know I shouldn't have tried if they were good but I'm frustrated) I am not sure what to do I even cleaned the entire dryer top to bottom. The dryer heats fine just cuts off and displays the HE error. I even checked the continuity on the heating element also good and it's not shorted out. Save me. If I need to provide more info let me know.
