What Does Error Code nG Mean on a Samsung Dryer?

No gas — burner failed to ignite (gas models).

The dryer's igniter glowed but the flame sensor never detected ignition, or gas flow is absent. Samsung gas dryers retry ignition a few times, then lock out with nG. The most common causes are a closed gas valve, a failed igniter, or a worn flame sensor.

What Causes Error Code nG?

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 or supply interrupted 35% of cases
  2. 2
    Igniter cracked or burned out 30% of cases
  3. 3
    Flame sensor (radiant sensor) failed 20% of cases
  4. 4
    Gas valve coils/solenoids failed 15% of cases

How to Fix Samsung Dryer Error Code nG

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

    Confirm gas supply

    Verify the shutoff valve behind the dryer is open and other gas appliances in the home work.

  2. 2

    Observe the igniter

    With the front panel removed, start a heat cycle and watch the burner: no glow means a failed igniter; glow without flame points to gas valve coils.

    🔩 Samsung dryer igniter ($20–$45)
    ⚠️ Gas appliance — shut off the gas valve and unplug before any disassembly; if you smell gas, stop and ventilate.
  3. 3

    Replace flame sensor or valve coils

    If the igniter glows and shuts off without flame, replace the valve coils; if the flame lights then drops, replace the radiant flame sensor.

    🔩 Gas valve coil kit ($20–$40) 🔩 Flame sensor ($15–$30)
    ⚠️ Do not bypass safety sensors. Leak-test fittings with soapy water after reassembly.

How to Reset Error Code nG

Restore gas supply, unplug the dryer for 5 minutes, and restart a heated cycle.

Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

Frequently Asked Questions

Can I keep using my Samsung Dryer when error nG appears? +
It is not advisable. The dryer may still power on, but running it while nG is active can worsen the heating fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes nG on a Samsung Dryer? +
Across reported Samsung dryer repairs, the most frequent is gas supply valve closed or supply interrupted (35% of cases), igniter cracked or burned out (30%), then flame sensor (radiant sensor) failed (20%). Check them in that order before replacing any parts.
nG keeps coming back after a reset — what should I check next? +
A reset only clears the stored nG fault; if it returns, the heating problem is still present. Move on to the physical checks — confirm gas supply, then observe the igniter — 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 Samsung Dryer error nG? +
A DIY repair typically runs $15–$90 in parts, versus $180–$350 for a professional service call, so handling it yourself saves around $165. Expect the work to take 1–3 hours.
