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

• No spark at one burner usually means the spark electrode (igniter) itself, not the module. On dual-fuel ranges and CT cooktops the large 15K burner electrode is Wolf 802449 (it supersedes the older 815563) and fits DF30/DF36/DF366/DF486G/DF604/DF606 and CT36G-2; surface-burner electrodes also ship as the 800063/800064/800065 set by burner size. A cracked ceramic, burnt-off tip, or a lead that arced to the burner body kills the high-voltage spark to that one position while every other burner still lights — we swap the electrode, not the module, when only one fire is dead.
• Dead spark across the WHOLE top points at the spark module, because one module fires multiple burner points. On R36/R48 ranges that's the 6-point module Wolf 815507 (used on serials before 17209023 on R36 / 17255730 on R48) — Wolf superseded it with the single-point 829016 design on later serials, so serial-check drives which part we order. CT30G/CT36G cooktops run the single-point module 801232 (also cataloged as 809420 / 815552, the Tytronics RI-120A-1). A no-output module leaves every electrode silent even though gas valves open normally.
• The cheapest 'no spark' that isn't a part at all: a moisture-soaked igniter after a boil-over or a wet clean. Wolf's own guidance is to dry the burner (hairdryer on low) and let it sit — water bridges the spark gap to ground and bleeds off the charge so the electrode either clicks without lighting or won't spark at all. We dry and retest the igniter wells before condemning any electrode or module, which clears a large share of after-cleaning no-spark calls with zero parts.
• Burner cap and ring placement is a real no-spark cause on Wolf, not an excuse: the spark electrode needs a clean ground path to the burner head, so a cap that's off-center, sitting proud, or seated on debris misdirects the arc and the burner won't light. Wolf specifies the cap/ring be centered over the burner head and sit flat (and on older screw-mount caps, tightly fastened). We reseat and clean the cap-to-head interface before any electrode goes on the truck.
• A stuck or shorted spark-ignition switch behind the valve can present as no usable spark — the push-ignite contact fails closed after a spill and feeds the module continuously, so the top clicks endlessly but a burner you're trying to light gets no clean ignition window. The check is continuity per switch: a switch reading continuity at all settings is condemned and replaced. We meter the switches before assuming the module, because a single stuck switch mimics a module fault.
• Power and reset come first on a total no-spark: the igniters are electric and do nothing without supply. Wolf's documented step is to kill the breaker to the unit for at least 30 seconds, restore, and retest — a wedged control or a backed-out connection can drop spark to the whole top. We verify the unit actually has power and run the 30-second reset before metering the 801232/815507-class module, so we don't sell a board on a power problem.
• The hot-surface (glow-bar) igniter Wolf 718601 / 813541 — used on the commercial/foodservice oven line (AFS/CAF/CH and related) — is a different animal from the residential spark-ignition electrodes: it glows to light, it doesn't spark. We name it only to rule it out: on a residential GR/R/DF/CT no-spark we're working the spark module, electrode and ignition switch path, not a glow-bar, so the diagnosis stays on the 802449 electrode / 815507 / 801232 module / switch chain.

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

• The recurring Toronto pattern on Wolf no-spark is the after-cleaning call: an owner deep-cleans or has a boil-over, water bridges the spark gap to ground, and the burner clicks without lighting (or goes silent) — a meaningful share resolve on drying and cap reseating with no part, while the genuine failures split cleanly into single-burner (electrode) versus whole-top (module) once we're on site.
• We come to these calls with the 802449 large-burner electrode (supersedes 815563) and the 800063/800064/800065 electrode sizes, the single-point cooktop module 801232 (809420/815552), and the 4-point 815509, plus a meter for the spark-ignition switches; the serial-specific R36/R48 6-point 815507 / superseding 829016 module is confirmed against the unit's serial and ordered authorized when the whole top is dead.
