What Does Error Code GAS Mean on a LG Dryer?

Gas supply error — no gas detected (gas dryer models only).

On gas models, the control monitors for a confirmed flame during the ignition sequence. The igniter first glows to reach ignition temperature, then the gas valve coils open to release gas. If no flame is sensed within the allotted ignition attempts, the GAS code fires. Unlike a general heating fault, this code specifically points to the gas delivery or ignition chain — supply valve, igniter, or valve coils — rather than thermistors, thermostats, or the electric heating element.

Models affected: LG gas dryer models only, such as the DLG3601W; electric models (DLEX/DLE series) do not display this code
What owners report: Owners commonly report this appearing after moving the dryer or after gas service work, when the shutoff valve was left partly closed. A frequent quick win is simply confirming the valve behind the dryer is fully open and that other gas appliances still work; if the igniter glows but no flame appears, the gas valve coils are the usual suspect.

What Causes Error Code GAS?

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

  1. 1
    Gas supply valve closed 45% of cases
  2. 2
    Gas igniter failure 30% of cases
  3. 3
    Gas valve coils failure 20% of cases
  4. 4
    No gas supply to home 5% of cases

How to Fix LG Dryer Error Code GAS

🔧🔧🔧 Advanced DIY Est. time: 1–3 hours
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Check the gas supply valve

    Confirm the gas shutoff valve behind the dryer is fully open.

  2. 2

    Check home gas supply

    Confirm other gas appliances in the home are working.

  3. 3

    Test the igniter

    The igniter glows orange before the gas flame lights. If it glows but no flame, the gas valve coils have failed.

    ⚠️ Work with gas appliances only if qualified. If in doubt, call a technician.
  4. 4

    Replace igniter if not glowing

    No glow = igniter failure.

Frequently Asked Questions

Can I keep using my LG Dryer when error GAS appears? +
It is not advisable. The dryer may still power on, but running it while GAS is active can worsen the heating fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes GAS on a LG Dryer? +
Across reported LG dryer repairs, the most frequent is gas supply valve closed (45% of cases), gas igniter failure (30%), then gas valve coils failure (20%). Check them in that order before replacing any parts.
GAS keeps coming back after a reset — what should I check next? +
A reset only clears the stored GAS fault; if it returns, the heating problem is still present. Move on to the physical checks — check the gas supply valve, then check home gas supply — since the code will reappear until the root cause is resolved. This is an advanced repair involving deeper disassembly or electrical testing.
How much does it cost to fix LG Dryer error GAS? +
A DIY repair typically runs $30–$60 in parts, versus $200–$450 for a professional service call, so handling it yourself saves around $170. Expect the work to take 1–3 hours.
Which LG Dryer models show error GAS? +
GAS is documented on LG gas dryer models only, such as the DLG3601W; electric models (DLEX/DLE series) do not display this code. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
