What Does Error Code NF Mean on a Samsung Oven?

No flame detected — gas ignition failure (gas range models).

On gas models, the control monitors the oven's flame-sensing circuit during ignition. When the igniter glows, it should draw enough current to open the safety gas valve, letting gas flow and light. If no flame is confirmed within the expected window — because the igniter is too weak to open the valve, ports are clogged, or gas is shut off — the board fires NF and cuts gas as a safety measure. This differs from electric heating faults, which report failed elements or sensor readings rather than absent flame.

Models affected: Samsung gas ranges, including the NX58R5601SS
What owners report: Owners commonly report NF appearing after a big spill or boil-over clogs the burner ports, or after the gas was shut off for other work. A weakening igniter that glows but no longer lights promptly is a frequent culprit, and many find that cleaning the ports or replacing the igniter resolves it.

What Causes Error Code NF?

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

  1. 1
    Igniter too weak to open gas valve (most common) 55% of cases
  2. 2
    Clogged burner ports from spilled food 25% of cases
  3. 3
    Gas supply valve closed 15% of cases
  4. 4
    Igniter failure 5% of cases

How to Fix Samsung Oven Error Code NF

🔧🔧 Moderate DIY Est. time: 30–60 min
⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.
  1. 1

    Check gas supply

    Ensure gas supply valve behind range is fully open. Check other gas appliances in the home.

  2. 2

    Clean burner ports

    Clogged burner ports prevent gas flow. Remove burner cap, clean ports with a pin or toothpick.

    ⚠️ Do not use water — let burner dry completely before igniting.
  3. 3

    Test the igniter amperage

    A Samsung oven igniter draws 3.2–3.6A when working correctly. Below 3A = too weak to open gas valve.

    🔩 Clamp ammeter
  4. 4

    Replace the igniter

    If igniter glows but draws < 3.2A, replace it. This is the most common NF repair.

    ⚠️ Gas igniter replacement: always test for gas leaks after.

How to Reset Error Code NF

Check gas supply and burner cleanliness. If NF persists, test igniter amperage.

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

When to Call a Professional

All gas igniter work should be checked for leaks with soapy water after repair. If you smell gas, do not ignite — call the gas company.

Average professional repair cost for this issue: $200–$480

Frequently Asked Questions

Can I keep using my Samsung Oven when error NF appears? +
It is not advisable. The oven may still power on, but running it while NF is active can worsen the heating fault or damage related parts. Treat it as a soon-as-possible repair.
What most commonly causes NF on a Samsung Oven? +
Across reported Samsung oven repairs, the most frequent is igniter too weak to open gas valve (most common) (55% of cases), clogged burner ports from spilled food (25%), then gas supply valve closed (15%). Check them in that order before replacing any parts.
NF keeps coming back after a reset — what should I check next? +
A reset only clears the stored NF fault; if it returns, the heating problem is still present. Move on to the physical checks — check gas supply, then clean burner ports — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.
How much does it cost to fix Samsung Oven error NF? +
A DIY repair typically runs $40–$80 in parts, versus $200–$480 for a professional service call, so handling it yourself saves around $160. Expect the work to take roughly 30–60 minutes.
Which Samsung Oven models show error NF? +
NF is documented on Samsung gas ranges, including the NX58R5601SS. Other units sharing the same control platform can display it too, so the fixes here generally transfer across the series.
