Samsung Dryer Error HE2 — What It Means & How to Fix It

What Does This Error Mean?

HE2 is a gas valve error on Samsung gas dryers. It means the dryer tried to heat but the gas valve did not open correctly — or the burner did not ignite as expected. Your dryer runs but produces no heat, leaving clothes wet even after a full cycle. This is a critical error because it involves your gas supply and ignition system. Do not attempt to repair the gas valve yourself — gas appliance work requires a qualified technician.

Common Causes

One or more gas valve coils (solenoids) have failed — these electromagnets open and close the gas flow
The igniter has failed and is not generating enough heat to open the gas valve's thermal switch
The gas supply to the dryer has been interrupted — the shutoff valve may be closed or gas pressure is low
The flame sensor or radiant sensor has failed and is blocking the valve from receiving power
The dryer's control board has a fault that is preventing the gas valve circuit from being energized

How to Fix It

First, check whether the gas supply valve behind the dryer is fully open. The valve handle should be parallel (in line) with the gas pipe — not perpendicular (across) the pipe.

A partially closed or fully closed gas shutoff valve is a simple and common cause of HE2. This is the one check you can safely perform yourself without any tools.
Check whether other gas appliances in your home — stove, water heater, furnace — are working normally. If none of them are working, contact your gas utility company immediately.

If your gas supply is interrupted at the meter or utility level, no gas appliances in your home will work. Your utility provider handles gas supply issues — call them first in this scenario.
Unplug the dryer from the electrical outlet. If the gas valve is fully open and other appliances work, do not attempt further inspection yourself. Call a licensed appliance technician.

Gas dryer repair beyond checking the supply valve requires testing igniter resistance, gas valve coil resistance, and flame sensor voltage. This requires proper equipment and training.
Check whether your dryer is under Samsung's 1-year warranty. Gas valve components and igniters are covered under the standard warranty. Call 1-800-726-7864 with your model and serial number.

The model number sticker is inside the door opening on the door frame. Have the serial number ready as well — it is on the same sticker and confirms the manufacturing date.
If out of warranty, schedule a repair with a licensed appliance technician. Provide them with the HE2 code and the dryer model number so they can bring the most likely replacement parts.

Gas igniter kits for Samsung dryers typically cost $25 to $60 in parts. Gas valve coil kits cost $20 to $50. Labor charges of $100 to $200 are typical for these repairs.

When to Call a Professional

HE2 always requires professional service on the gas components. Gas valve replacement and igniter diagnosis should only be performed by a licensed appliance technician or gas technician. Improper gas appliance repair is a serious safety hazard — gas leaks can cause fires or carbon monoxide buildup. Expect repair costs of $150 to $350 for igniter or gas valve coil replacement. Call Samsung support at 1-800-726-7864 to check warranty, or contact a licensed appliance repair service.

Frequently Asked Questions

Is it safe to use my gas dryer when HE2 is showing?

Do not use the dryer while HE2 is active. HE2 means the gas valve or ignition system is not functioning correctly. While the dryer may spin, it will not heat — leaving clothes damp. More importantly, a gas appliance with a suspected valve or igniter fault should be inspected before use. Stop using it and arrange for professional diagnosis.

How do I know if my dryer is gas or electric?

Look at the power cord and the connection at the wall. Electric dryers use a large 240V outlet with a distinctive 3 or 4 prong plug. Gas dryers use a standard 120V outlet — the same size as a regular appliance — plus a gas pipe connection at the back. You can also check the model number: Samsung gas dryers have a 'DVG' prefix (the G stands for gas). Electric models have 'DVE' (E for electric).

Can I smell gas when HE2 appears?

If you smell gas near the dryer at any time, do not attempt to diagnose the error — leave the house immediately and call your gas utility's emergency line. HE2 usually means the gas valve did not open properly, so there should not be a gas leak in most cases. However, any smell of gas — which smells like rotten eggs due to an added odorant — should always be treated as an emergency.
