Samsung Dryer Error Code hE2 — Gas Igniter / Gas Valve Failure
What this means
The hE2 error code is specific to Samsung gas dryers. It indicates the gas igniter (glow bar) is not heating to ignition temperature, or the gas valve solenoids are not opening to allow gas flow to the burner. Without a functioning igniter and gas valve, the dryer runs but produces no heat. This is one of the most common failures on gas dryer models.
Alternate codes: HC2
Step-by-step fix
5 stepsVerify gas supply
Check that the gas shutoff valve behind the dryer is fully open. Also verify other gas appliances in your home are working to confirm the gas supply is on.
If you smell gas at any point, do not proceed — leave the area and call your gas utility company.
Access the burner assembly
Unplug the dryer. Remove the lower front panel to expose the burner assembly. You will see the gas valve (with solenoids mounted on top), the igniter (a flat glowing element), and the flame sensor.
Take photos of the wiring connections before disconnecting anything.
Test the igniter
Disconnect the igniter wires. Set your multimeter to ohms and test across the igniter terminals. A good Samsung gas dryer igniter reads between 50 and 400 ohms. An OL reading means it is burned out.
Even if the igniter glows, if it does not reach the correct temperature (bright orange/white), it won't trigger the gas valve to open.
Test the gas valve solenoid coils
There are typically two solenoid coils on the gas valve. Disconnect each and test resistance — expect 1,000–2,000 ohms per coil. An OL reading means that coil is burned out.
Gas valve coils often fail intermittently — the dryer heats at first but loses heat mid-cycle. Both coils should be replaced together even if only one tests bad.
Replace faulty components
Replace the igniter if out of range, or the gas valve coil kit if either coil is defective. Reconnect all wiring, reassemble, and run a test cycle to verify the burner lights and stays lit.
After replacing the igniter, let the first cycle run its full length to confirm consistent heating throughout.
When to call a professional
If you are not comfortable working around gas components, hire a qualified appliance technician or gas fitter. Improper gas work can create dangerous leaks.
