One of the most common issues Samsung dryer users’ faces is the HE/HC error.
This error appears when the dryer cannot heat properly, leaving clothes damp even after a full cycle.
It might look like a complicated problem, but most of the time the cause is simple and preventable.
Learn more about this error in our detailed guide.
1. The Main Reason: Poor Ventilation and Lint Build-Up
The number one cause of dryers not heating is poor airflow.
Samsung dryers, like all modern dryers, rely on a steady flow of air to move heat into the drum and remove moisture.
When the lint filter is not cleaned regularly, airflow slows down.
Even more important is the external ventilation system — the duct that leads outside your home.
In apartments, this vent often runs through long lines in walls and ceilings, making it more likely to get clogged with lint.
These clogs block hot air, forcing the dryer to overheat and trigger the HE/HC error or stop heating completely.
Regularly cleaning both the lint filter and the vent duct is essential to keep your dryer working efficiently.
2. Heating Element and Thermostat Issues
If cleaning the vents doesn’t solve the problem, the heating element itself may be faulty.
Over time, constant use can burn out the element or damage the high-limit thermostat.
Both parts are responsible for generating and controlling heat.
If one fails, the dryer will tumble clothes but produce no warmth.

3. Blown Thermal Fuse
A clogged vent often causes overheating, which can blow the thermal fuse.
This fuse acts as a safety device, shutting off power to the heating system when temperatures rise too high.
Once blown, it must be replaced. However, replacing the fuse without fixing the airflow problem will likely result in another failure.
4. Power Supply Problems
Samsung electric dryers require 240V to heat correctly.
If one breaker trips, the dryer may run but not heat.
Gas dryers, on the other hand, need both gas supply and proper ignition.
A quick check of circuit breakers or gas valves can save time before calling a technician.
5. Common Causes of Dryer Heating Issues
Dryers can stop producing heat for several reasons, leaving laundry damp and frustrating to manage.
Poor airflow is a leading cause, often caused by clogged vents or filters.
This buildup restricts heat movement and can trigger safety shutdowns.
6. Steps to Restore Efficient Performance
Regularly cleaning the lint filter and duct system can prevent most issues.
Checking the heating components, thermostat, and power supply ensures the dryer maintains consistent performance and avoids costly repairs.
Conclusion
If your Samsung dryer stops heating, don’t panic.
Start with the basics: clean the lint filter and the entire vent system.
This is especially important in apartments, were long vent lines clog more often.
If that doesn’t fix it, check for heating element, thermostat, or power issues.
In most cases, keeping the ventilation clean will prevent the HE/HC error and keep your dryer running efficiently for years.
