Samsung dryer HE code: what it means and what to check
Your Samsung dryer may stop after a few minutes, flash HE or hE, and feel hotter than normal inside the drum. This page explains the usual airflow checks first, then the parts a technician tests when the code comes back.

The Samsung dryer HE code means the dryer thinks it is overheating. The single most common cause is trapped heat from a clogged lint screen or restricted exhaust vent.
Check these first
Safe to do yourself. Unplug the appliance before you start.
- Stop the cycle and let the dryer cool
If the drum feels very hot, leave the door open and give the dryer time to cool before touching the lint area or vent. Don’t keep restarting it while the code is showing.
- Clean the lint screen, then wash it
Pull the lint screen and remove lint by hand. If you use dryer sheets, wash the screen with warm water and a little dish soap because softener film can block air even when the screen looks clean.
- Check airflow at the outside vent hood
Run the dryer on a heat cycle for a short test and look at the outside hood. The flap should open with a steady air push; a weak push, stuck flap, lint mat, or bird nest points to a vent problem.
- Inspect the flexible vent behind the dryer
Unplug the dryer first. Look for a crushed hose, too many bends, or a loose connection packed with lint, then put it back without smashing it behind the dryer.
- Try a short reset after cleaning
After the lint screen and vent path are clear, unplug the dryer for 5 minutes. If HE comes back right away on a cold dryer, stop testing cycles and have the temperature circuit checked.
Conditions that make this more likely
Lint and dust build up faster than you'd think
Dryer vents, refrigerator condenser coils and dishwasher filters collect lint, pet hair and dust. Homes with pets, long vent runs or dusty surroundings usually need these cleaned more than once a year.
Boards fail earlier in hot rooms
Electronics are rated for room temperature. In a garage or an unconditioned laundry room in summer, a control board can sit well above that for hours a day. Before replacing a board, a good technician confirms the parts it controls test good, since a shorted pump or valve can take out a new board too.
What a technician tests
Most likely part first. These are for a technician with a meter and the tech sheet, not a weekend project.

Can I reset a Samsung dryer HE code?
You can unplug the dryer for 5 minutes after cleaning the lint screen and vent. A reset only clears the display; it won’t fix trapped heat, a bad thermistor, or a stuck heat relay.
Why does HE show up right after I press Start?
When HE appears in the first minute on a cold dryer, the thermistor is a common suspect. It sits on the blower duct, which is the part many owners miss when they only replace parts on the heater box.
Is HE the same as HC on a Samsung dryer?
Samsung groups hE, HC, HC4, and 1 HC as heating errors. They point to overheating or a heat-control fault, so the same airflow and temperature-sensor checks apply.
Should I keep running the dryer if clothes are still drying?
No. HE means the dryer is seeing an overheat condition, and repeated restarts can trip safety fuses or damage the heater area.
Could this be a house power problem?
On electric Samsung dryers, incorrect voltage or power cord issues can cause heat complaints. A homeowner can confirm the dryer is on its own proper outlet, but live voltage checks should be left to an electrician or appliance technician.
