What One Burner Dead means on your Dacor rangetop (dacor rangetop one burner dead)
Dacor never wrote an error code for this rangetop condition, so this page names the symptom instead of inventing one. Each burner on a rangetop has its own valve, its own gas line branch, and its own spark point, so one burner failing while the rest work normally almost always points to something local to that single station rather than a shared supply or wiring problem.

Symptoms
What follows helps you confirm that your Dacor rangetop has this specific problem rather than one that merely resembles it on a rangetop.
- One specific burner produces no click, no spark, and no flame.
- Every other burner on the same rangetop lights and holds flame normally.
- The affected burner’s knob turns with the same resistance as the working ones.
- Swapping grates or caps between burners does not move the problem to a different station.
Common causes
Several different problems can put a Dacor rangetop into this state, and working through them in order of likelihood is what keeps a rangetop repair to what it actually needs.
- Failed spark module segment — some Dacor rangetops wire each burner to its own igniter circuit, so one segment can fail alone.
- Disconnected or corroded wire at that station — a loose spade connector under the cooktop breaks the circuit to one burner only.
- Blocked orifice at that burner — debris fully sealing one gas port stops fuel flow to just that station.
- Failed valve at that position — the mechanical valve behind the knob does not open even though the knob turns freely.
Troubleshooting steps you can try
Work through these checks on your rangetop in order before calling anyone out, and stop wherever mains voltage, gas, a hot surface or a sealed component on the rangetop is involved.
- Confirm the knob for the dead burner turns with the same feel as a working one, ruling out a jammed knob.
- Swap the burner cap and grate from a working station onto the dead one to rule out a seated-part issue.
- Check for gas odor when the knob is turned to confirm whether fuel is reaching that burner at all.
- Inspect the visible wiring under the cooktop for a loose connector near that burner position, without disturbing the gas line.
- Book a technician once the mechanical checks are done, since diagnosing the igniter circuit or valve requires removing the cooktop.
Parts a technician may replace
The parts most often in question on a rangetop here are the spark ignition module, burner valve, wiring harness, and igniter electrode. Which one has actually failed on your Dacor rangetop is settled by measurement, and nothing is ordered for the rangetop before that.
When to call a technician
A technician isolates the dead station with a multimeter on the spark circuit and valve before opening the gas line to confirm the problem. This is rated Medium severity, so there is no emergency on the rangetop — but if One Burner Dead keeps returning to the rangetop, have the cause confirmed before a part is bought. The technicians who will see your rangetop are ours, not Dacor’s, and their labor is covered for 30 days.
