Dacor Stove Repair in Toronto — Gas burner clicks but won't light

• One burner clicks but never catches: the surface spark electrode (legacy 72164, superseded to DE81-08766A) is cracked or fouled, so it ticks but the spark is weak or jumping to the grate instead of the burner base. We inspect the ceramic insulator for hairline cracks and check the gap to the burner cap before condemning it; a $30-$90 electrode swap usually restores ignition on that single position.
• No burner sparks at all (or all click but none light): the shared multi-point re-ignition (spark) module has failed - one module feeds every burner, so when it dies you get all-or-nothing behaviour. Dacor uses several point-counts depending on the platform (a 4-point 86526/DE81-03926A, a 5-point 86527/DE81-03927A, and a 6-point 86528/DE81-03928A), so we don't guess: we confirm by turning any single knob and watching whether all electrodes tick together, then pull the exact module by the unit's model/serial. The same SGG/SGM range family shows up under more than one module, which is why a model-blind order is a coin toss.
• One knob position is dead - no click, no gas - while the others light fine: that's a contaminated or failed burner igniter switch behind the knob (OEM 103789, supersedes to DE81-07625A; confirmed fitment on DCT305/DCT365 cooktops). A spill or boil-over runs into the switch and either opens the contact (dead position) or sticks it closed. We test for continuity in the OFF position; continuity off means the switch is shorted and gets replaced.
• Burner sparks normally but still won't light after a cleaning or boil-over: residue or cleaning-product film on the electrode tip and burner ports is blocking the gas-to-spark path, not a failed part. Per Dacor/RepairClinic troubleshooting we clean the electrode with a soft brush, clear the ports, and confirm the burner cap is seated square - many no-light calls resolve here without any 72164 or module replacement.
• Weak, lazy yellow flame that's hard to light after a move or gas-type change: the range is still on the wrong orifices (NG orifices on an LP supply or vice-versa). The electrode and module test healthy - it's a gas-mix problem corrected with the Nat-to-LP conversion kit (86151K) plus air-shutter adjustment, which is TSSA gas-fitter scope, not a parts swap.
• Clicks and releases gas but won't establish flame across multiple burners: we verify the house gas valve is fully open and the manifold/regulator is delivering before touching ignition parts. Combined with a continuity test of the spark module, this separates a true gas-delivery issue from a failed re-ignition module (86526/DE81-03926A, 86527/DE81-03927A or 86528/DE81-03928A, by platform) so we don't parts-cannon a four-figure-channel luxury range.

Dacor gas burner clicks but won't light in Toronto — the local specifics

• The recurring Toronto pattern on Dacor no-light calls is post-cleaning failure: a deep-clean or boil-over drives water and detergent film into the burner igniter switch (103789/DE81-07625A) or onto the spark electrode (72164/DE81-08766A), and the homeowner reports either a single dead position or weak/no spark right after cleaning. The next most common is an all-burners-out call that traces to one shared spark module rather than to the burners themselves.
• We carry the common surface-ignition parts to these Toronto calls: a spark electrode (72164/DE81-08766A), the matching burner igniter switch (103789/DE81-07625A), and electrode-cleaning tools to rule out a film/spill short first. The multi-point spark modules (4-point 86526/DE81-03926A, 5-point 86527/DE81-03927A, 6-point 86528/DE81-03928A) are confirmed by model/serial and ordered through the authorized channel rather than carried blind, since the right one depends on the platform.
