HE on a Samsung dryer is a heating error — the dryer's temperature sensors saw something out of range and shut the heat down to stay safe. It can be as simple as a restricted vent choking the airflow, or a heating component that's failing. Because it involves heat and airflow, start with the vent (which is also the fire-safety issue) and go from there.
A clogged vent traps heat, spikes the internal temperature, and trips the HE safety code — and it's the leading cause of dryer fires, so it matters most.
Check it: Clean the lint trap, pull the dryer out and check the duct behind it, and check the exterior vent flap. A full vent-run cleaning clears the restriction and the fire risk — that's our dryer-vent cleaning service.
If airflow is good but the dryer overheats or the element shorts, HE can appear. The element is the part that actually makes the heat.
Check it: If the vent is clean and clear but HE persists, the heating element or its circuit needs a tech to ohm it out and replace.
The thermistor reports drum temperature to the control. If it reads wrong, the control sees a false high/low and throws a heating error.
Check it: A tech ohms the thermistor against spec — an affordable sensor replacement if it's out of range.
Safety thermostats and the thermal fuse can fail (often after a vent restriction cooked them), cutting or misreading heat.
Check it: These are inexpensive parts a tech replaces — and they should be checked alongside clearing the vent that likely stressed them.
Repair — start with a vent cleaning (often the whole fix, and a safety must), and the heat-side parts (element, thermistor, thermostat) are all affordable relative to a new dryer.

It's a heating / high-temperature error — the dryer shut the heat off because a temperature sensor read out of range. The most common root cause is a restricted vent; less often it's the heating element or thermistor.
Clean the lint trap and clear the exhaust vent first — a restricted vent is the top cause and a fire risk. If HE stays after the vent is clean, a tech checks the heating element, thermistor, and thermostats.
It's a safety shutdown, so the dryer protected itself — but the common cause (a clogged vent) is a genuine fire hazard. Clear the vent promptly. Your $50 Quick Check credits toward any repair if a part is needed.
