I'm the homeowner. About 6 weeks ago the dryer stopped - drum would not turn, error showed tO. Ordered OEM heating element assembly and thermistor. Replaced heating element assembly, no change. Replaced thermistor. Dryer began working fine. Now, 6 weeks later, the dryer will run for less than a minute, stops, and it shows an hE (overheating) error. No lint issue. Pulled new heating element assembly out. Tested for short on new heating element. No issue. Put original assembly back in after testing for short on old heating element. No short on old element. Started dryer and same behavior, runs less than a minute, stops, error code hE. Would appreciate next suggested troubleshooting steps. Thanks.

Check the vent line and maybe use a shop vacuum or leaf blower also make sure the exhaust hose is not pinched and do an extra drain and spin before switching to dryer

Check your vent it may be clogged causing it to over heat if that's not it it will be you main control board at that point

I will be happy to assist you. You will want to check the vent to make sure the damper is opening, and there are no other blockages. An easy test is to disconnect the vent from the back to see if the dryer runs normally.

I guess that I should not have been so concise. No lint issue meant that I had checked everything for kinks, blockages, lint build up, in other words, no airflow problems. That was the first and most common step in everything I read online before posting.

My wife ran the dryer on the air-fluff setting (no heat) and the dryer ran for a long time with no issues.

Are there any tests I can perform to confirm that as 'springdinger' suggested, the main control board is at fault?

And by the way, SamsungLou , Mr. Moderator, the link you posted just takes you to the error code page that essentially says: Check for lint/blockages/airflow issues, and if not call for service. Not very helpful.

If there are no blockages, that means that service is needed. You can use the following link to locate a service center near you: https://www.samsung.com/us/support/service/locations/

And finally:

Following SpringDingers advice, I ordered a new control board from PartsDr.com. That was a mistake. They sent me a 'new' part that was not in a manufacturers box, was not in any kind of electrostatic packaging like you would expect for an electronic part, and the box it was in looked used. Now the part itself did 'look' new, but when I installed it, it was dead. Dryer did not play the tones when power was restored, and the control panel would do nothing when I pushed the power button. So I put my old control board back in. I restored power, got the tones, and control panel lit up as it should when I pressed the power button. Jury is still out whether or not I am going to get anything back on the piece of junk PartsDr sold me.

I had not been behind the dryer itself while doing all the troubleshooting (my wife had). Turns out the factory wiring diagram was in a ziplock back on the back. Included in the wiring diagram was a section on troubleshooting with pictures showing the placement of the four main sensors affecting heating. In it they are labeled the Thermistor (the temperature measuring sensor), Thermostat 1 (next to the Thermistor on my model - also referred to as Thermal fuse 85C/185F), Thermostat 2 (Hi-Limit - on heating element housing in the middle) and Thermostat 3 (aka Thermal Cut-Off Fuse 160C/320F - on heating element housing opposite end from element connections). I had previously replaced the thermistor before, so no need to check it again, right? Wrong. According to the troubleshooting info, it should have had a resistance of approximately 10K ohms at room temperature (77F), and it measured just under 1K ohms. I had ordered a new pack of the four sensors (from someone other than PartsDr). I measured the new one in the package, and just as the instructions said, 10K ohms. So, I installed it, put it back together for the umpteenth time, and viola! The dryer was drying again. So for other DIY troubleshooters, please replace all four sensors, if you must, before ordering a new control board.
