Samsung Oven Error Code NF

What Does Error Code NF Mean on a Samsung Oven?

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

The oven or one of the surface burners did not ignite successfully. The gas igniter has glowed but no gas flame appeared, or the igniter failed to glow.

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

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.

   🔩 Samsung oven igniter ($40–$80)

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