Samsung Dryer Error Codes: What They Mean and How to Fix Them
What common Samsung dryer codes such as tS, HC and 9C1 mean, which checks are safe to try, and when it is time to book a technician.
Samsung dryers display a code when something stops them running normally. Many of these are caused by a blocked lint screen or vent, which is easy to fix, while others point to a sensor, control or power supply fault. Models without a digital display show their codes as blinking lights instead.
To find your model number, look for the label on the dryer, usually inside the door opening or on the back. Codes vary by model and model year, so use this page as a guide and confirm against your manual.
Unplug the dryer before cleaning behind it, and never open the cabinet or touch wiring or the heating parts.
A blocked vent is a fire risk, so clean the lint screen after every load and have the vent checked if the dryer runs hot.
Gas dryers must only be repaired by a licensed gas technician.
Airflow, heat and temperature codes
| Code | What it means | What you can safely check | When to call a technician |
|---|---|---|---|
| tS (t5, tC, tO, t0, tE, tE3, tC5, tCS, 1 tC) | Temperature or temperature sensor problem | Clean the lint screen and, if accessible, the vent and exhaust duct | If it returns after cleaning the lint screen and vent |
| HC (hE, HC4, 1 HC) | Dryer is getting too hot | Clean the lint screen and the vent system | If cleaning does not clear it, or you suspect low supply voltage |
| Clg (Cl9, Cg, C9, C80, C8o, C8, C90, C9o) | Vent blockage test found a clog | Clean the lint filter and the exhaust vent | If the code returns once the vent is clear |
Samsung dryer tS (t5, tC, tO, t0, tE, tE3, tC5, tCS, 1 tC) error
The dryer is reporting a temperature problem or a fault with the sensor measuring it. The most common cause is trapped heat from a clogged lint screen or vent, so clean both before anything else. If the code returns after that, the sensor or heating circuit needs a technician. A symbol that looks like an upside-down F is a lowercase t, so treat it as this code.
Samsung dryer HC (hE, HC4, 1 HC) error
This means the dryer is overheating, or sometimes that the heater is not getting hot enough. Blocked lint screens and vents are the usual cause, so clean them first. Low voltage on an electric dryer can also be involved and should be checked by a qualified person, not by opening the dryer yourself.
Samsung dryer Clg (Cl9, Cg, C9, C80, C8o, C8, C90, C9o) error
These codes only appear after you run the dryer's vent blockage test. Clg or Cg means the vent is clogged, C80 means about 80 percent blocked and C90 means over 90 percent blocked. Clean the lint filter and the exhaust vent, then test again.

Power, door and control codes
| Code | What it means | What you can safely check | When to call a technician |
|---|---|---|---|
| 9C1 (9E, 2E, 9E1) | Voltage supply problem | Make sure the dryer is on its own circuit with no extension cord | If the supply checks out and the code stays |
| dC (dE, dF, do, d0, 1 DC, 1 dF) | Door or door latch not detected as secure | Check nothing is caught in the door and close it firmly until it latches | If the door or latch is damaged |
| bE (bE2, bC2, 6E, 6E2, 6C2) | Stuck button on the panel | Switch the dryer off and press and release every button | If a button is damaged or the code returns |
| AC (Et, AE, EEE, AE4, AE3, AE5, E3, 1 AC) | Internal communication error | Turn the dryer off for 60 seconds, then on again | If the code remains after the restart |
| FC (FE, 1 FC) | Invalid power frequency | Restart the cycle | If it returns |
| HC2 | Gas ignition fault | Nothing to try yourself: gas work is for a licensed gas technician | Do not attempt repairs; use a licensed gas technician |
Samsung dryer 9C1 (9E, 2E, 9E1) error
The dryer is seeing an abnormal electrical supply. Confirm it is on its own circuit and not running through an extension cord. On stacked washer and dryer sets, Samsung notes that a 9C1 can also be reported if the dryer is operated within seconds of switching the washer on. Persistent codes need an electrician or technician to check the supply.
Samsung dryer dC (dE, dF, do, d0, 1 DC, 1 dF) error
The dryer cannot confirm the door is closed and latched. Look for clothing caught in the door and shut it firmly. If the door will not stay closed or the latch looks damaged, a technician can repair or replace it.
Samsung dryer bE (bE2, bC2, 6E, 6E2, 6C2) error
The dryer thinks a button is held down. Power it off and work each button back and forth. If the code comes back after switching on, the control panel needs repair.
Samsung dryer AC (Et, AE, EEE, AE4, AE3, AE5, E3, 1 AC) error
Parts inside the dryer have stopped communicating with each other. Switch it off for a minute and restart it. If the code remains, the control board or its connections need a technician.
Samsung dryer FC (FE, 1 FC) error
The dryer reports a power source frequency it cannot accept. Restarting the cycle is the first step. If the code persists, the supply or control board needs checking by a technician.
Samsung dryer HC2 error
HC2 appears in Samsung's list of other errors as a gas ignition error, so it applies to gas dryers. Gas appliance faults must be handled by a licensed gas technician. We service electric appliances only and do not work on gas, so please contact a gas technician rather than trying to fix it yourself.
Informational codes
| Code | What it means | What you can safely check | When to call a technician |
|---|---|---|---|
| dn | Software update in progress | Leave the dryer powered; do not unplug it | If it is still showing after 24 hours |
| CL | Child Lock is on | Turn Child Lock off using the steps in your manual | Not normally needed |
Samsung dryer dn error
The dryer is installing new firmware and will restart itself when finished. Do not unplug it or cut power while the code is showing, as that can leave it unusable. Only if it is still displayed after a full day does it need service.
Samsung dryer CL error
Child Lock disables the control panel buttons, and on some models it can lock the door as well. It is a setting and not a fault. Turn it off following your manual.
How to reset your Samsung dryer
For codes without specific steps, Samsung suggests a simple power cycle. Switch the dryer off for a couple of minutes, then back on, and restart the cycle.
- Switch the dryer off.
- Wait 2 to 3 minutes.
- Switch it back on and restart the cycle.
Frequently asked questions
What does tS mean on my Samsung dryer?

What does HC mean on my Samsung dryer?
It means the dryer is overheating, usually from a blocked lint screen or exhaust vent. Clean both and try again. HC2 is different: it is a gas ignition code, and a licensed gas technician must handle it.
What does 9C1 mean on my Samsung dryer?
It is a voltage supply problem. Make sure the dryer is on its own circuit with no extension cord. If it continues, have the supply checked by a qualified person.
What does dn mean on my Samsung dryer?
It means a software update is being installed. Leave the dryer powered and do not unplug it. It should restart by itself when the update finishes.
