Dacor Range Not Igniting: Gas Supply, Igniter, Spark Module & Safety Valve
Quick answer
A Dacor range that won't ignite at all — no click, no spark, no flame on any burner — is most often a tripped circuit breaker (igniters run on electricity even on gas ranges), a gas supply interruption, or a failed spark module. A single burner that won't light points to a wet or misaligned igniter specific to that burner. Check the breaker and gas shutoff first, then inspect the igniter on the affected burner.
When a Dacor range will not ignite, the symptom tells you where to look: all burners dead points to gas supply or the ignition control module; one burner dead points to that burner's ceramic igniter or burner cap. Dacor's professional-style ranges — Modernist, Epicure, Discovery, and Heritage series — share a sealed-burner design with electronic ignition that depends on both gas pressure and 120 V AC electricity. A fault in either supply kills ignition. Post-2016 Modernist models with Samsung SmartConnect controls add a third layer: software state faults that can disable burners without any hardware failure at all.
1. Confirm gas supply and circuit breaker
Gas ranges — including all Dacor models — use 120 V AC power to generate the igniter spark. If the circuit breaker for the range has tripped, you will have no spark on any burner and no oven ignition, even though the gas supply is fine. Check the breaker panel and reset if tripped. Also confirm the gas shutoff valve behind or beneath the range is fully open. In Northern Virginia homes that have had recent plumbing or gas work, the appliance shutoff is sometimes left partially closed. Finally, confirm gas is flowing to other appliances in the home (a gas water heater or dryer) — if none work, contact Washington Gas immediately.
2. Dry the surface burner igniters
Dacor's sealed-burner igniters are ceramic spark electrodes beside each burner. A boilover, overspray during cleaning, or high kitchen humidity saturates the ceramic, causing one of two behaviors: the igniter clicks continuously without producing a flame, or it produces no click at all. Remove the burner grate and burner cap, dry the igniter tip and surrounding area thoroughly with a clean cloth, and air the range for 30 minutes. A hairdryer on low directed at the igniter port accelerates drying. This step resolves the majority of single-burner no-light complaints on Dacor ranges — no parts required.
3. Reseat the burner cap and check the electrode gap
Dacor's sealed burner caps must sit flat and correctly oriented on the burner base. A cap that is off-center — shifted by a boilover or moved during cleaning — puts the ceramic igniter electrode at the wrong angle relative to the burner's gas exit ports. The spark fires into open air rather than across the gas stream, and no flame results. Lift the cap, align it (Dacor's Epicure and Modernist multi-ring caps have a locating notch or orientation mark that should face the front of the range), and press it down flat. The electrode gap between the ceramic tip and the burner cap should be approximately 4–6 mm; if the ceramic tip is chipped or broken, the gap is inconsistent and the igniter must be replaced.
4. Test the spark module — all burners dead
If every burner on the Dacor range produces no click and no spark despite a live circuit, the ignition control module (spark module) has failed. The spark module converts 120 V AC to high-voltage pulses distributed to each igniter electrode. A failed module delivers no signal to any burner. On Dacor ranges, the module is typically located behind the control panel or inside the front cavity of the range. Testing requires a multimeter to confirm the module is receiving input voltage and a spark tester to confirm it is not producing output — a specialist repair. Do not confuse this with a child lock on post-2016 Dacor models: the Modernist child lock disables all burner operation and displays no icon on some firmware versions. Navigate Settings → Lock or hold the lock button for five seconds to confirm the child lock is off before assuming module failure.
5. SmartConnect and control board faults — post-2016 Dacor Modernist
Dacor Modernist ranges built after 2016 incorporate Samsung SmartConnect controls that can disable burner operation through software state. Three conditions prevent burner ignition without any hardware fault: (a) demo or showroom mode, which suppresses gas flow to prevent actual cooking in a display environment — check Settings for any active modes; (b) lost Wi-Fi pairing that puts the control board in a restricted operation state on some firmware versions — reconnect the range to the home network or perform a factory reset (hold Timer and Power simultaneously for five seconds on most models); (c) a firmware hang that requires a hard reset — disconnect the range from power at the breaker for 60 seconds, then restore power. These steps restore ignition on Dacor Modernist ranges that are otherwise mechanically intact.
When to Call a Specialist
If gas supply, breakers, and control software are confirmed normal and the range still will not ignite, the fault is in the igniter module wiring harness, the spark module output, or the gas safety valve circuit — all require disassembly of the range body and access to high-voltage ignition components. Dacor Modernist control boards also carry firmware-specific repair requirements beyond a reset.

Frequently Asked Questions
Why won't any burner on my Dacor range ignite?
When no burner on a Dacor range will ignite, start with the circuit breaker — gas ranges need 120 V AC for the ignition spark. A tripped breaker kills all ignition instantly. Also check the gas shutoff valve behind the range and the SmartConnect control panel on post-2016 Modernist models for any active lock or demo mode. If all of those are clear, the spark module has likely failed.
One Dacor burner won't light but the others work — what is wrong?
A single Dacor burner that will not light almost always has a wet, dirty, or misaligned igniter ceramic, or a burner cap sitting off-center. Remove the cap, dry the igniter area completely, reseat the cap with the locating notch facing front, and try again. If the igniter ceramic is visibly chipped or cracked, the electrode must be replaced.
How much does Dacor range ignition repair cost in Northern Virginia?
