Dacor Stove Repair in Toronto — Gas burner clicks constantly

• All burners keep clicking no matter which knob is on (or they keep sparking after the flame is already lit): Dacor's surface ignition runs through one shared multi-point re-ignition module that uses flame rectification - the lit gas flame acts as a one-way rectifier, conducting a weak current from the electrode back to the grounded burner frame, and the module stops pulsing once it senses that current. When the module fails it never sees the flame and pulses every electrode non-stop. Dacor uses the 4-point 86526 (Samsung DE81-03926A, fitment confirmed on SGM304 / ERD60) and the 5-point 86527 (DE81-03927A, confirmed on SGM365 / RI305) by platform - we confirm all electrodes tick together off one knob, then pull the exact module by model/serial rather than model-blind.
• One burner clicks forever even after it lights: a cracked or fouled surface spark electrode (legacy Dacor 72164, which cross-references to the Samsung-era DE81-08766A - the OEM path may also run 72164 -> 72164AM, so we confirm the exact number by serial) breaks the flame-sense feedback path on that position, so the module never registers a flame and keeps re-sparking. We inspect the ceramic insulator for hairline cracks and check the gap to the burner cap; a healthy electrode is what lets the module 'see' the flame and quit. A $30-$90 electrode swap restores normal cut-off on that single position before anyone touches the harder-to-source module.
• Constant clicking with every knob in the OFF position is almost always a contaminated or stuck-closed burner igniter switch behind the knob (legacy Dacor 103789, superseded by Samsung DE81-07625A; confirmed fitment on DCT305 / DCT365 cooktops and the SGM304/SGM365 series). A boil-over or cleaning water bridges the switch contacts and sends continuous voltage to the spark module regardless of where the dial sits. We meter each switch for continuity in OFF - continuity off means it is shorted and gets replaced, not the module.
• Clicking that started right after a spill, boil-over, or wiping the cooktop down: this is moisture trapped under the burner caps or in the switch area, not a failed part. Per Dacor/RepairClinic troubleshooting we pull the caps, dry every component thoroughly, and let the switch area air out before quoting hardware - a large share of 'won't stop clicking' calls clear here with zero parts, which is why we dry first and condemn second.
• A burner has a good flame but the igniter keeps sparking on that one position: the burner cap is not seated square, or the orifice holder/burner base is not grounding properly, so the spark path can't complete to ground and the module never senses ignition. We re-seat the cap, clear the ports, and verify the burner base ground before naming any electrode or module - a misaligned cap mimics an electrode fault exactly.
• Slow, lazy clicking or a spark rate well below the healthy three-to-five-per-second, often pre-dating the failure: per spark-module diagnostics this points to reversed polarity or a bad/missing ground at the 120VAC outlet feeding the range, and sustained reverse polarity will eventually destroy the spark module itself. We check outlet polarity and ground with a meter on any persistent-clicker before condemning the 86526/DE81-03926A or 86527/DE81-03927A module, so an order-only part isn't swapped onto a wiring fault that will just kill the new one too.

Dacor gas burner clicks constantly in Toronto — the local specifics

• The recurring Dacor-clicking pattern we see across Toronto is moisture-driven: a boil-over or a post-cleaning wipe-down bridges a burner igniter switch (103789/DE81-07625A) or wets the caps, and the cooktop clicks non-stop with the knobs off - drying and a switch continuity test resolve most of these without parts. The second cluster is genuine re-ignition module flame-sense failure on the SGM/ERD sealed-burner cooktops, where every electrode ticks together off any one knob and the module (86526/DE81-03926A 4-point or 86527/DE81-03927A 5-point) has to be ordered by serial.
• We carry to these calls a meter for switch-continuity and outlet polarity/ground testing, the surface spark electrode 72164/DE81-08766A, and the burner igniter switch 103789/DE81-07625A - the high-probability fast fixes. The 4-point 86526/DE81-03926A and 5-point 86527/DE81-03927A re-ignition modules we confirm by model/serial and order through the authorized channel rather than carry blind, since fitment is platform-specific and these are an order-only part, not a shelf item.
