Quick Answer
A Samsung Dryer HE error indicates a heating problem. The dryer is detecting that it is not reaching the proper temperature during operation. Common causes include a clogged vent, blocked lint filter, faulty heating element, defective thermistor, blown thermal fuse, or a malfunctioning control board. Cleaning the vent system and checking heating components will resolve most HE errors.
What Does the Samsung Dryer HE Error Mean?
The HE error code on a Samsung dryer stands for a heating error. During a drying cycle, the control board monitors temperatures inside the dryer. If temperatures fail to rise as expected or heating components do not operate properly, the dryer displays the HE code and may stop the cycle.
This safety feature helps prevent poor drying performance and potential overheating conditions.
Common Causes of a Samsung Dryer HE Error
Several issues can trigger the HE code:
- Clogged dryer vent
- Blocked lint filter
- Faulty heating element
- Defective thermistor
- Blown thermal fuse
- Damaged wiring connections
- Restricted airflow
- Failed control board
Fortunately, many of these problems can be diagnosed at home.
How to Fix a Samsung Dryer HE Error
Step 1: Reset the Dryer
A temporary control board glitch can sometimes trigger the error.
- Turn off the dryer.
- Unplug it from the outlet.
- Wait 5 minutes.
- Plug it back in.
- Start a test cycle.
If the error does not return, a temporary electronic fault may have caused the problem.

Step 2: Clean the Lint Filter
Restricted airflow is one of the most common causes of heating errors.
- Remove the lint screen.
- Clear away all lint.
- Wash the screen with warm water if fabric softener buildup is present.
- Allow it to dry completely before reinstalling.
A clean lint filter improves airflow and drying efficiency.
Step 3: Inspect the Dryer Vent
A blocked vent can prevent proper heat circulation.
- Disconnect the dryer from power.
- Pull the dryer away from the wall.
- Disconnect the vent hose.
- Remove lint and debris from the vent.
- Check the exterior vent hood for obstructions.
Many HE errors are resolved after a thorough vent cleaning.

Step 4: Check for Kinked or Crushed Vent Hoses
Even partially blocked ducts can restrict airflow.
- Inspect the vent hose behind the dryer.
- Look for sharp bends or crushed sections.
- Straighten the hose where possible.
- Replace damaged vent tubing if necessary.
Proper airflow is critical for maintaining safe operating temperatures.
Step 5: Test the Heating Element
A failed heating element can prevent the dryer from producing heat.
- Disconnect power to the dryer.
- Access the heating element housing.
- Inspect for visible damage.
- Use a multimeter to test continuity.
- Replace the element if it fails continuity testing.
Heating elements naturally wear out over time.
Step 6: Inspect the Thermistor and Thermal Fuse
Temperature sensors and safety devices help regulate dryer heat.
- Locate the thermistor and thermal fuse.
- Disconnect the wiring harnesses.
- Test both components with a multimeter.
- Replace any component that does not meet manufacturer specifications.
A failed thermistor or thermal fuse can trigger the HE error code.
Step 7: Inspect the Control Board and Wiring
If all other components test properly, the control board may be at fault.
- Disconnect power.
- Access the main control board.
- Inspect wiring connections.
- Look for burn marks, corrosion, or damaged connectors.
- Replace damaged components as needed.

When to Call a Professional
Consider professional service if:
- The HE code returns after vent cleaning.
- The heating element tests good but the dryer still does not heat.
- Wiring damage is discovered.
- The control board appears defective.
- You are uncomfortable performing electrical testing.
A qualified technician can diagnose advanced electrical issues safely.
How to Prevent Samsung Dryer HE Errors
To reduce the chances of future HE errors:
- Clean the lint filter after every load.
- Inspect the vent system regularly.
- Clean the entire vent at least once per year.
- Avoid crushing the vent hose behind the dryer.
- Do not overload the dryer.
- Address airflow issues promptly.
Routine maintenance helps improve drying performance and extends appliance life.
Frequently Asked Questions
What does the Samsung dryer HE code mean?
The HE code indicates a heating-related problem that prevents the dryer from reaching or maintaining the proper temperature.
Can a clogged vent cause a Samsung HE error?
Yes. Restricted airflow from a clogged vent is one of the most common causes of the HE error.
Will resetting the dryer clear the HE code?
A reset may clear temporary electronic faults, but underlying heating problems must still be repaired.
Can a bad heating element cause an HE error?
Yes. A failed heating element can prevent the dryer from generating heat and trigger the code.
Is it safe to continue using a dryer with an HE error?
No. Continuing to operate the dryer may result in poor performance and could potentially damage components.
Conclusion
A Samsung Dryer HE error typically points to a heating or airflow problem. Start by cleaning the lint filter and vent system, then inspect the heating element, thermistor, thermal fuse, and control board if necessary. In many cases, restoring proper airflow resolves the error and returns the dryer to normal operation.
