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

• Moisture in the burner after a boil-over or wet clean is the single most common "won't light" call on a Wolf top, and it is the cheapest fix — Wolf's own guidance is to let the burner dry and use a hairdryer on a low setting to speed it up. A spill that soaks the spark electrode and the switch behind the knob makes the burner either click without lighting or click with the knob off; on these we dry the electrode well and the spark switch before condemning a single part. Drying beats a parts swap on a large share of these.
• Burner cap/head misalignment is the second honest no-part fix: Wolf documents that the burner rings/caps must sit centered over the burner head and flat (and on older heads, screwed down tight). A cap off its seat puts the gas ports out of line with the spark electrode tip, so it sparks into open air and the burner won't catch. We re-seat and re-center the cap and confirm a clean port-to-electrode gap before touching ignition hardware.
• A cracked, fouled or worn surface-burner spark electrode is the leading hardware cause of one burner that clicks but won't light while its neighbours fire fine. On GR gas ranges the part is the 45-degree spark electrode igniter Wolf 815544 (previous number 714415); on the larger 15K burners of DF/CT-series dual-fuel tops it is electrode 802449, which is interchangeable with Wolf number 815563 (retailers catalog the two as cross-references for the same 15K burner electrode). A hairline crack in the ceramic bleeds the spark to ground, so it ticks but never throws a hot arc — we inspect the tip and meter before swapping the electrode for that exact burner.
• When EVERY burner clicks but none light, the fault is upstream of any single electrode — it is the shared spark module, not all the electrodes failing at once. On R36/R48 ranges the 6-point module is Wolf 815507 (secondary ID 809416), which on later serials Wolf transitions to a single-/multi-point module 829016 (previous number 815552; fits CG243/CG304/GR/DF/RT/R-series by serial). Because the module is serial-gated, we confirm the unit's serial against Wolf's break points (GR uses bridge part 826610 in the #18191030–#18193132 window; DF uses 817763 before #11172943) before ordering, so the right module lands the first trip.
• A bad spark switch — the switch that slides over the valve shaft behind the knob — produces the same "clicks but won't light," or the opposite "won't spark at all," on the burner whose knob you turn. It is a distinct part from the electrode and the module: the switch tells the module to fire when you push/turn the knob, so a dead switch on that position kills the spark for that burner. We test the switch contacts on the affected position before assuming the electrode or module, because a dead switch and a dead electrode read very differently on a meter.
• No spark on ANY burner is a power fault, not a gas fault — Wolf's troubleshooting is explicit that the igniters are electric and will not spark or click without power. We confirm the range is on a real outlet (not an extension cord), reset the breaker, and run Wolf's 30-second power-down before condemning ignition parts; if there is gas and a clean spark but still no light, only then do we look at gas type/regulator or a clogged burner port (standard service practice is to clear it with a pin, never drilled).
• On R-series gas ranges Wolf documents surface burners that click or won't light while the oven is running, and gives steps for it (riser, ventilation hood, breaker reset, cap cleaning/positioning). We treat it as a reproduce-and-isolate diagnostic: we run the fault with the oven both on and off, because a burner that only misbehaves during oven use points us at the shared spark module/path (815507 / 829016) rather than that one burner's electrode.

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

• The recurring Toronto pattern on Wolf "burner won't light" is moisture-driven and seasonal: after holiday cooking and big boil-overs we see a wave of all-burners-click-no-light and clicks-with-knob-off calls that turn out to be a spill-soaked electrode and spark switch, not failed parts — dried out, the top lights again. The genuine hardware pattern is a single cracked surface electrode on one burner (GR 815544 / DF 802449) while the rest fire, and on older R36/R48 units the shared 6-point module (815507) showing up as every burner clicking at once. We always test for all-burners-tick before condemning a module.
• We bring the dry-out kit (low-heat blower) and burner-cap re-seat tools to every Wolf gas-light call, plus the GR 45-degree spark electrode 815544 on the van; the DF/CT-series 15K electrode 802449 (interchangeable with 815563), the 814883 electrode/wire kit, and the serial-matched spark module (815507 or 829016, with bridge parts 826610/817763 noted by serial) are ordered against the unit's serial through Wolf authorized distribution so the return visit closes the call.
