On Samsung dryers, HE, hE, HC and 1HC are heating/overheating codes, and Samsung notes they're often caused by a clogged lint screen or vent. If the vent is clear, the usual failed parts are the heating element, thermal fuse or thermostats (electric) or the igniter and gas valve coils (gas). Temperature-sensor codes (tS, tO) point to the thermistor or its wiring.
Samsung dryer heating and temperature codes
Samsung groups its dryer codes by system. The exact code depends on the model year — older units show HE or hE, newer ones add a number like 1HC — but the meaning is the same family.
| Code(s) | What Samsung says | What we usually find |
|---|---|---|
| HE hE HC 1HC | Heating problem / dryer overheating | Restricted vent first; then element, thermal fuse, thermostats, or gas igniter/valve |
| tS tO tE tC | Temperature sensor issue | Thermistor failed or its connector is loose; often after overheating |
| Clg C80 C90 | Vent clogged / 80% / 90%+ blocked (FlowSense models) | Lint and dust packed in the duct or roof/wall hood |
| 9C1 9E 2E | Abnormal voltage supply | Loose power cord connection, breaker or house wiring issue |
| dE dF d0 | Door or door-sensor problem | Door not latched, worn latch, or door switch |
If your Samsung dryer shows Clg or C90, take it seriously: the dryer is telling you the vent is badly restricted — a fire risk, not just an efficiency issue.
Check airflow first — really
Most Samsung heating codes start with poor airflow. The dryer gets too hot inside, the safety devices trip, and heat shuts off. Here's how to check in five minutes:
- Clean the lint screen — and wash it with warm, soapy water if dryer sheets have left a waxy film. Hold it up to a faucet: water should pass through.
- Look behind the dryer. Flexible foil duct crushed against the wall is a common culprit, especially after the dryer was pushed back.
- Go outside while it runs. The flap on the vent hood should open and you should feel strong airflow. Weak air means a clog somewhere in the run.
- Power-cycle the dryer. Unplug it (or flip the breaker) for a few minutes after clearing any restriction, then start a timed dry.
In the Tri-Cities, fine dust blows into vent hoods and mixes with lint, so vent runs pack faster than in wetter climates. Long runs to the roof in two-story homes are the worst offenders.
When the vent is clear: the usual failed parts
Electric Samsung dryers
- Heating element — the coil inside the heater housing breaks, often after a stretch of overheating. It's among the most common Samsung dryer repairs we make.
- Thermal fuse — a one-time safety fuse that opens when the dryer overheats. Depending on the model it cuts heat or stops the dryer entirely.
- High-limit and cycling thermostats — safety and regulation devices on the heater housing and exhaust.
- Half-tripped 240V breaker — the drum still turns, but there's no heat. Flip the double breaker fully off and back on.
Gas Samsung dryers
- Igniter — no orange glow through the burner window means the igniter or something upstream failed.
- Gas valve coils — igniter glows, then shuts off without lighting the burner.
- Flame sensor — burner lights briefly then goes out, or never lights.
Remember that a blown thermal fuse or high-limit thermostat is usually a symptom. We always clear or confirm the vent before replacing them so the new part doesn't blow in a month.
Is a Samsung dryer worth repairing?
Yes, in most cases. Heating elements, fuses, thermostats, thermistors and igniters are moderate-cost parts, and the drum, motor and cabinet on a Samsung dryer usually outlast them by years. The exception is a unit with multiple major failures at once — we'll tell you if that's what we find.
Samsung heating code won't clear?
If the lint screen and vent are clean and the code keeps returning, a thermistor, fuse or element has probably failed. We fix Samsung gas and electric dryers throughout Kennewick, Pasco, Richland, West Richland and Benton City. Our office gives you the diagnostic fee before anyone drives out, and it's part of the repair total once the work is approved. Our technician tests the dryer and gives you one price, in writing, before the first part comes out; nothing starts until you say yes. We don't post prices because parts prices swing several-fold between brands, models and suppliers.

Samsung dryer FAQ
What does HE mean on a Samsung dryer?
HE (and hE, HC or 1HC on newer models) is a heating error — the dryer is overheating or not heating as expected. Samsung notes it's often caused by a clogged lint screen or vent. If the vent is clear, the heating element, thermal fuse, thermostats or gas components are the usual failures.
How do I reset my Samsung dryer after an HE code?
Clear the lint screen and vent first, then unplug the dryer or switch off the breaker for a few minutes and restart. If the code returns, a part has likely failed and needs testing.
Why is my Samsung dryer running but not heating with no code?
On electric models, check the 240-volt breaker first; a half-tripped breaker lets the drum spin without heat. Otherwise, a failed heating element or thermal fuse is most likely. On gas models, check that the gas valve is open and watch for the igniter glow.
What does C90 mean on a Samsung dryer?
On Samsung dryers with vent monitoring, C90 means the vent is more than 90% blocked. Clean the vent run and the exterior hood before using the dryer again.
