Quick answer
A Samsung dryer that tumbles but will not heat most often has a restricted vent that tripped a safety part, half of the double breaker tripped on an electric model, a blown thermal fuse, or a failed heating element; on gas models, the igniter or gas valve coils. An HE code means a heating error and HC overheating, usually airflow. Clean the lint filter and the vent, reset both halves of the breaker, and run a timed high-heat cycle. Angi puts typical dryer repairs at $100–$430. Call (888) 217-0236 to reach an appliance repair company taking calls in your ZIP; the line is answered 24/7.
Follow the short menu, then your 5-digit ZIP. The line goes quiet for a few seconds while it connects; stay on. If it does not connect, call once more: companies taking calls change minute to minute.

Samsung dryers that stop heating follow the same pattern as most dryers: airflow and power first, then a short list of parts. The display often helps, because many models show a code.
Codes That Point to Heat
| Code | Usual meaning |
|---|---|
| HE, hE | Heating error: not heating or too slow |
| HC, hC | Overheating, usually a restricted vent |
| tS, tO | Temperature sensor shorted or open |
| Filter check light | Lint filter or airflow |
The full list is in Samsung dryer error codes.
Check These First
- 1Clean the lint filter, then go outside and feel the vent hood while the dryer runs. Weak airflow is the most common root cause, because the dryer overheats and a safety part cuts the heat.
- 2Reset the breaker. Electric dryers use a double breaker. If one half trips, the drum turns but the element gets no power. Switch it fully off, then on.
- 3Gas models: make sure the gas valve behind the dryer is open and other gas appliances work.
- 4Run a timed high-heat cycle to rule out a sensor cycle ending early.

What Usually Fails
| What you notice | Likely part |
|---|---|
| No heat at all, electric, breaker fine | Thermal fuse or heating element |
| No heat after a blocked-vent episode | Thermal fuse, sometimes the high-limit thermostat |
| Some heat, very slow drying | Restricted vent, or a cycling thermostat |
| Gas model: igniter glows, no flame | Gas valve coils |
| Gas model: no glow | Igniter or flame sensor |
On many models the thermal fuse sits on the heater housing or exhaust duct, behind the rear panel. A fuse that blows again after replacement means the vent is still restricted. The U.S. Fire Administration names failure to clean as the leading cause of home dryer fires.
What a Repair Costs
Angi puts typical dryer repairs at $100–$430, about $180. Fuses and thermostats are low-cost; an element or gas valve coils cost more. See dryer repair and the general dryer not heating guide.

Frequently Asked Questions
Why is my Samsung dryer running but not heating?
Usually a blocked vent, half of the breaker tripped, a blown thermal fuse or a failed heating element. Gas models can lose the igniter or the gas valve coils.
Where is the thermal fuse on a Samsung dryer?
On many models it sits on the heater housing or the exhaust duct at the back, behind the rear panel. Unplug the dryer before removing any panel.
What does HE mean on a Samsung dryer?
A heating error: the dryer is not heating, or not reaching temperature in time. Check the breaker and vent, then the heating parts.
