Dacor Stove Repair in Toronto — No spark (igniter failure)

• The hard "no spark on ANY burner" call on a Dacor sealed-burner cooktop almost always traces to the one shared multi-point re-ignition module that feeds every electrode at once, so when it dies the whole cooktop goes dead together. Dacor uses the 4-point 86526 (Samsung DE81-03926A, fitment confirmed on ERD60 and other 4-burner platforms) and the 5-point 86527 (DE81-03927A, confirmed on RI305 / SGG365A / DCT305SLP / DCT365SLP / GCS120) by platform. We confirm the all-or-nothing pattern by turning any single knob and watching whether NONE of the electrodes tick, then pull the exact module by model/serial rather than model-blind, because the same SGG/DCT family shows up under more than one point-count.
• Before any order-only module is condemned on a total-no-spark Dacor, we verify the module is actually getting power: the spark PCB takes 120VAC with the N terminal wired straight to line neutral and the L terminal fed through the surface switches, so a dead-module symptom can really be a lost neutral, an open switch harness, or no power reaching the board. We meter for 120V at the module input first - a no-spark cooktop with no voltage at the module is a power/harness fault, not an order-only module job.
• A single position that clicks on every other burner but produces NO spark of its own is a cracked or fouled surface spark electrode. On the DCT / SGG / SGM sealed-burner cooktop family the surface igniter is the single-burner kit DE81-02696A (Dacor 76482-001, also superseding 66915 / 76482 / 86438), which packs one electrode, spring, C-clip and heat-shrink per burner - we confirm the exact number by serial against the model's sub-cooktop diagram before staging. The ceramic insulator develops a hairline crack and the spark jumps to ground inside the body or to the grate instead of arcing to the burner cap, so that one position stays dark. We inspect the insulator and the electrode-to-cap gap; a single-burner electrode swap restores spark on that one position before anyone touches the shared module.
• One knob position that produces no click and no spark at all (while the rest spark normally) points to a contaminated or open burner igniter switch behind that knob - legacy Dacor 103789, superseding to Samsung DE81-07625A, fitment confirmed on DCT305 / DCT365 cooktops. A boil-over or cleaning water runs into the switch and opens the contact, so the module never gets the L-side signal to fire that electrode. We meter the switch for continuity when the knob is turned to LIGHT; no continuity in the ON position means the switch is open and gets replaced, not the module.
• No spark or a sluggish spark on a newly installed or recently re-plugged Dacor is a wiring fault at the outlet, not a failed ignition part: per spark-module diagnostics, a spark rate well below the healthy three-to-five per second - or no spark with the clicking sound absent - points to reversed polarity or a lost/missing ground at the 120VAC receptacle. Sustained reverse polarity will also eventually destroy the spark module itself, so we check outlet polarity and ground with a meter on any no-spark-after-install range before condemning the 86526/DE81-03926A or 86527/DE81-03927A board.
• No spark right after a cleaning, spill, or boil-over is moisture bridging the switch contacts or the electrode body, not dead hardware - and counterintuitively this can read as BOTH no-spark AND constant-clicking depending on whether the short opens or closes the path. Per Dacor/RepairClinic troubleshooting we pull every burner cap, dry the electrodes and the switch area thoroughly, and let it air out before quoting parts; a meaningful share of "won't spark" calls clear here with zero parts, which is why we dry and re-test first and condemn the DE81-02696A electrode or 103789/DE81-07625A switch second.
• A burner that has a healthy electrode but still won't spark to the cap is usually a grounding/seating fault: the spark needs a completed path from the electrode tip across the gap to the grounded burner base, so a cap that is cocked off-center or a burner base that isn't grounding lets the module fire with no visible arc at the burner. We re-seat the cap square, clear the ports, and confirm the burner base ground before naming any electrode or module - a misaligned cap mimics a dead-electrode no-spark exactly.

Dacor no spark (igniter failure) in Toronto — the local specifics

• The recurring Toronto pattern on Dacor no-spark is the split between an instant single-visit fix and a parts-gated return: a dead single position almost always clears on the first trip with a stocked DE81-02696A surface electrode kit or a 103789/DE81-07625A switch, whereas a whole cooktop with NO spark on any burner usually means the order-only shared module (86526/DE81-03926A 4-point or 86527/DE81-03927A 5-point) and a second visit once the point-count is confirmed by serial. We also see a steady stream of moisture-after-boil-over no-spark calls in Toronto condos that clear with a thorough dry-out and zero parts.
• To a Dacor no-spark call in Toronto we carry the fast-moving stocked items - the DE81-02696A (Dacor 76482-001) single top-burner spark-igniter kit for the DCT/SGG/SGM cooktops and the 103789/DE81-07625A burner igniter switch - plus a meter to check the 120V outlet polarity/ground and to test the switch and module input before we commit to an order-only 86526/DE81-03926A or 86527/DE81-03927A re-ignition module through the authorized distributor channel.
