After enough Dacor cooktops on the bench, burner won't ignite stops being a mystery. The tell on Dacor is usually perma-Flame re-ignition thermocouple response delay on Heritage series causing flame dropouts during simmer-to-high transitions, and knowing that saves you from chasing the wrong part for an afternoon.
The short answer: Dacor Cooktop burner won't ignite#
On Dacor, burner won't ignite almost always starts with perma-Flame re-ignition thermocouple response delay on Heritage series causing flame dropouts during simmer-to-high transitions — a fault that falls inside the $80–$250 band below. That is what sets these machines apart from the universal cooktop advice, and why the fix is different.
The failure modes below are specific to Dacor cooktops — they are what set Dacor apart from the generic burner won't ignite checklist.
| Likely Dacor-specific cause | How often we see it | Typical repair |
|---|---|---|
| Perma-Flame re-ignition thermocouple response delay on Heritage series causing flame dropouts during simmer-to-high transitions | Most likely | $80–250 |
| Illumina backlit control knob encoder dial skipping positions, jumping past the ignition detent during initial turn | Common | $80–250 |
| SimmerSear 18,000 BTU dual-ring burner inner ring flame extinguishing from gas orifice partial blockage by boilover residue | Common | $80–250 |
| Spark module ignition circuit failure on individual burner zones | Possible | $80–250 |
| LP conversion kit regulator pressure creep on Heritage gas cooktops causing progressively higher flame output and eventual ignition instability | Possible | $80–250 |

What you can safely check first#
You can narrow this down yourself. Here is what I have a Dacor owner look at before I quote anything.
- Take a close look at perma-Flame re-ignition thermocouple response delay on Heritage series causing flame dropouts during simmer-to-high transitions. You can usually spot it without pulling anything apart.
- Start by inspecting illumina backlit control knob encoder dial skipping positions, jumping past the ignition detent during initial turn. Catching it here tells you whether this is a quick fix or a real repair.
- Check for simmerSear 18,000 BTU dual-ring burner inner ring flame extinguishing from gas orifice partial blockage by boilover residue. Owners miss it because the generic guides never mention it.
- Confirm the model. Parts and known quirks differ across the DTG36M955FS, DTG30M954FS, HCT365GS and HCT486GS line, so find the model number on the door or frame before ordering anything.
Repair cost and when to call an EasyBear technician#
Where you land in the $80–$250 range depends on which failure it actually is. A straightforward fix like lP conversion kit regulator pressure creep on Heritage gas cooktops causing progressively higher flame output and eventual ignition instability sits near the $80 end; perma-Flame re-ignition thermocouple response delay on Heritage series causing flame dropouts during simmer-to-high transitions — more labor and often a sealed part — pushes toward the top. If the problem keeps coming back after a basic reset, it is worth booking an EasyBear technician rather than swapping parts on a guess.
