DCS Ranges NO-IGN Error: Burner ignition failure
The dcs ranges error code no-ign indicates Burner ignition failure. This guide covers symptoms, diagnostic steps, and repair options. What the NO-IGN Code Means on a DCS Range NO-IGN on DCS RDV2, RDV3, RGV2, and RGV3 ranges means the ignition system failed to light a burner after multiple spark attempts. The control system retries ignition […]

Answer to continue safely
Is it safe to keep using?
No. Do not attempt repeated manual ignition if the NO-IGN code is active. Repeated failed ignition attempts can allow gas to accumulate. Ventilate the area and address the fault before using the burner.
Can I reset the code?
Yes. After cleaning and drying the igniter and burner, a reset allows another ignition attempt. If the burner lights successfully, the fault is resolved.
When to stop immediately?
Stop if you notice: Gas odor is present during or after ignition failures — ventilate immediately and do not use the range., Igniter does not spark at all — no clicking sound from the module..
Symptoms You May Notice
Burner clicks but does not ignite
The igniter sparks repeatedly for several seconds but the burner flame does not establish. After the retry period, NO-IGN is displayed and the gas valve closes.
Burner ignites intermittently
The burner lights on some attempts but not others, suggesting a borderline igniter or partially blocked burner port rather than a complete failure.
Weak or single-point spark visible
The spark at the igniter tip appears weak, inconsistent, or fires from only one of the multiple igniter points, indicating a degraded igniter electrode.
Ignition works on some burners but not others
If specific burners fail to ignite while adjacent ones light normally, the fault is localized to that burner's igniter or port rather than a system-wide issue.
Possible Causes
Wet or contaminated igniter electrode
Water, grease, or food residue on the igniter tip prevents a strong spark. This is the most common cause and often resolves after thorough drying and cleaning.
DIY PossibleClogged burner ports
Food debris blocking the small gas ports around the burner cap prevents gas from reaching the igniter spark, causing ignition failure even when the spark is strong.
DIY PossibleFailed igniter module or spark electrode
The igniter module that generates high-voltage sparks, or the electrode itself, has failed and can no longer produce a spark strong enough to ignite gas reliably.
Requires ProfessionalSafe Checks You Can Do
-
1
Dry and clean the igniter and burner area
Remove the burner cap and grate. Dry the igniter electrode with a clean cloth and use a toothbrush to clean any food residue from the electrode tip and surrounding porcelain. Allow to air-dry for 30 minutes before retesting.
A hair dryer on low heat accelerates drying of a wet igniter — a very common cause of NO-IGN after stovetop cleaning.

2
Clear clogged burner ports
Inspect the burner cap for blocked ports. Use a straightened paper clip or a thin wire to clear each port. Rinse the cap, dry completely, and replace it in the correct orientation.
The burner cap must be seated flat and in the correct position — an off-center cap is a common cause of ignition failure after cleaning.

3
Confirm burner cap seating
After cleaning, ensure each burner cap sits perfectly level on the burner base. Wobble or tilting of the cap prevents proper gas distribution and ignition.
Some DCS burner caps have a locating pin — check that it is seated in the corresponding hole on the burner base.
When to Call a Professional
Contact a qualified technician if:
- Ignition module produces no spark despite cleaning.
- Spark electrode is cracked or the ceramic insulator is damaged.
- Multiple burners fail to ignite despite clean, dry conditions — suggesting a failed ignition control module.
