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

• Platform split first, same as the rest of this LG range platform: 'no spark' on an LG gas range is a COOKTOP spark-ignition fault, not the oven. LG's display F-codes are OVEN-side only (F9 = the oven failed to reach temperature - about 150F - within roughly five minutes of preheat, F11 = a communication error between the main control board and the display board), and the oven's flat glow-bar bake igniter (MEE61841401) plays no part in cooktop spark, so a surface burner that won't spark throws NO display code at all. That makes a dead-spark burner a silent-display isolation job worked in a fixed order on LRG ProBake freestanding, LSG ProBake slide-in and LDG/LTG gas double-oven families - electrode, then the per-burner spark switch/harness, then the shared spark module - and we never chase a control board for it.
• One burner clicks but throws no usable arc (or a weak arc that won't reach the gas) while the others spark fine = the spark electrode at that position is cracked or carbon-tracked, so the high-voltage pulse leaks to ground through a hairline crack in the ceramic insulator instead of jumping the gap. LG codes these electrodes by position - EAD60700530 is the general service electrode, with EAD60700501 left-front, EAD60700504 right-front and EAD60700502 carried as center/rear depending on the model (RepairClinic lists each position separately), so the exact part is model/position-specific. Per RepairClinic we inspect the ceramic for a crack and pull the insulated spark lead to watch for the arc flashing over to the burner box before swapping the electrode - a single-position fix that never touches the EBJ60659901 module.
• One knob position turns but produces NO click and NO spark while the rest spark normally = the spark ignition switch behind that knob has failed open, not the electrode or module. The switch only closes when the knob reaches the spark/LITE position to feed the module; a burnt or pitted contact means that position never signals the module, so there's no click and no arc on that burner alone. LG supplies this as the switch-and-harness assembly EBF60662901 (officially superseded to EBF60662911, which also covers Kenmore/Sears-branded LG ranges, per LG Parts / Parts Dr), so it carries the wiring for all the surface burners. Per RepairClinic's diagnostic order - if the OTHER burners spark fine, the switch for the dead position is the likely failed part - we meter that switch for continuity at the spark position before quoting the harness assembly.
• Burner cap and head seated off their locating tabs, or a boil-over that plugged the ports, makes a burner spark at the electrode but never light - and a cap sitting proud, rotated or warped can move the grounding edge so the electrode produces no usable arc at the gas at all. LG's own help-library guidance (LG Range - Why Won't My Burner Light) is to confirm the cap and head sit level and fully seated, brush moisture/debris off the cap, head, spark plug and heat-sensing rod with a soft brush, and clear a clogged port by poking it 5-10 times with a small needle without enlarging it. We do this cap/seat/port check first because a $0 reseat-and-clean resolves a large share of single-burner no-spark / no-light calls and keeps us from selling an electrode the range never needed.
• Moisture in the switches or at the electrode tip after a boil-over or a wet wipe-down kills the spark before any part is condemned - and it's a $0 fix on a same-day call. A spill that seeps down the knob shaft, or steam/cleaning water in the switch body, can bridge or short the spark switch so it bleeds spark energy off and no single burner gets a clean arc; a moisture-soaked ceramic at the electrode tip leaks the pulse to ground the same way. LG's guidance is to dry the cap, head, spark plug and sensing rod; field practice is to unplug the range and dry the switches (24h unplugged, or warm air from a hair dryer) and cycle each switch before condemning the EBF60662901 switch-and-harness. If spark returns once dry, no part is needed.
• Every burner is dead with no spark anywhere, and the electrodes and switches all test clean = the shared surface burner spark module, condemned LAST. LG EBJ60659901 (cross-references to EBJ62730001 / EBJ64465501, same 4210335 / AP6028872 / PS11761179 family across model years) powers every surface electrode at once, so a genuine module failure is all-or-nothing across the cooktop - no spark on any position even with everything bone-dry and the switches good. Per LG/RepairClinic procedure the module is the part to condemn only after the electrodes (EAD60700530 family) and switches (EBF60662911) check out, because on this platform a no-spark is far more often a cracked electrode, a moisture short, or a failed-open switch than a dead module.
• A module we replace that won't spark again, or burns out a second time, points at the receptacle - not the part. LG's spark module needs hot on 'L' and neutral on 'N' with a true ground; a reversed-polarity or ungrounded 3-prong outlet gives the module the wrong reference so it sparks erratically or not at all and can cook itself early. We meter the receptacle for correct polarity and ground on any no-spark-after-install or repeat-module call, and the range must be on a properly grounded 3-prong outlet - never a 2-prong adapter or extension cord - so the new EBJ60659901 doesn't fail the same way. On a polarized outlet the narrow slot is hot, the wider slot is neutral, the round pin is ground.

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

• The recurring LG-in-Toronto no-spark pattern is a single dead position with a cracked ceramic electrode - one burner clicks weakly or not at all while its neighbours arc clean - which we resolve at that position (EAD60700530 / position-coded electrode) without touching the shared module. The second recurring pattern is seasonal moisture: after holiday boil-overs and wet wipe-downs we see a wave of switches that bleed spark or short, where drying the EBF60662901-fed switches restores spark with no part. A whole-cooktop dead-spark traced to a genuine EBJ60659901 module is the least common of the three and is condemned only after the electrodes and switches test clean.
• We carry to these LG no-spark calls the position-coded spark electrodes (EAD60700530 plus EAD60700501 left-front / EAD60700504 right-front / EAD60700502 center-rear), the EBF60662911 spark ignition switch-and-harness assembly, and the EBJ60659901 spark module (with its AP6028872 / PS11761179 cross-referenced equivalent) - plus a 3-light polarity/ground tester so we can rule out a reversed or ungrounded outlet before replacing the module.
