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

• Spark with no flame on one burner is a cap/port problem before it is ever a part. LG sealed-burner ranges (LRGL ProBake freestanding, LSGL ProBake slide-ins, LDG gas double-oven) misfire when the burner cap and head are seated in the wrong location or a boil-over has plugged the ports. LG's own guidance is to lift the cap and brush the head with a soft brush; clearing a stubbornly clogged port with a fine pin is standard shop practice. We do this and a magnet/seat check first, because a $0 clean fixes a large share of single-burner 'won't light' calls and keeps us from selling an electrode the range never needed.
• Clicks but no spark, or a weak yellow spark, on a single burner points to the spark electrode at that position - LG part EAD60700530. The electrode fires the gas at the burner head; when its tip is cracked, carbon-fouled, or the ceramic is moisture-soaked it either won't arc or arcs too weakly to light. Note LG codes these electrodes by position (e.g. EAD60700501 left-front, EAD60700502 center, EAD60700504 right-front), so the exact part can vary by burner - we confirm the position before ordering. We diagnose by comparing to the other burners: if its neighbours spark clean and only one is dead, the electrode (not the module) is the failed part.
• All burners click continuously and none light - including after a knob is released - is the spark module signature, LG EBJ60659901 (cross-references to EBJ62730001 / EBJ64465501 across model years; same AP6028872 family). The module powers every surface electrode; when it fails or its relay sticks it sparks all positions at once or none at all. This is the part to condemn only after the electrodes and switches check out, since module failure is the one fault that hits the whole cooktop together rather than one burner.
• One burner that won't even start clicking when its knob is turned - while the others spark normally - is the spark ignition switch behind that knob, LG EBF60662901. The switch closes to send power to the spark module; a burnt or pitted contact means that position never signals the module, so there is no click and no spark on that burner alone. LG supplies this as a switch-and-harness assembly (superseded to EBF60662911), so it covers the wiring for the surface burners - we price that assembly honestly up front.
• A spark module that burns out fast or has to be replaced twice is, in our field experience, usually an outlet problem rather than a defective part. A reversed-polarity or ungrounded receptacle stresses the spark module - the range should be on a properly grounded 3-prong outlet with correct polarity, never a 2-prong adapter or extension cord. We meter the receptacle for polarity and ground on any repeat module failure so the new EBJ60659901 doesn't cook itself the same way.
• Burner lights then drops out, or only lights when held, on an LDG-series gas double-oven range is a flame-sensing/re-ignition pattern distinct from a dead electrode. On sealed burners the same electrode senses flame by rectification; a moisture-soaked or carboned electrode tip (EAD60700530) lets the module keep sparking or cut the burner after release. We dry and inspect the electrode and its lead before quoting, because intermittent re-spark is usually the electrode, not the EBJ-series module.
• Distinguishing a cooktop 'won't light' from an oven no-heat keeps the quote accurate: the surface burners use the EBJ spark module + EAD electrodes, while the oven burner uses the flat glow-bar igniter MEE61841401 and reports F9 when the oven can't reach temperature. A customer saying 'the gas won't light' often means the oven - we confirm which system is dead first so a cooktop electrode call isn't mis-diagnosed as an F9 oven igniter, or vice versa.

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

• The recurring Toronto pattern on LG 'gas burner won't light' calls is a single sealed burner clicking with no flame after a boil-over - cleaning and reseating the cap/head, or swapping the one fouled electrode (EAD60700530), resolves most of them, and only the smaller share that click on every burner at once turn out to be the spark module. A meaningful number of repeat-module calls in older Toronto houses trace back to an ungrounded or reversed-polarity outlet rather than the appliance.
• To these calls we bring the common LG spark electrodes (EAD60700530, in the relevant position variant), a spark module (EBJ60659901 / EBJ64465501-class), burner-port cleaning tools, and an outlet polarity/ground tester. The model-coded spark ignition switch-and-harness (EBF60662901-class) and the oven-side igniter MEE61841401 are ordered next-day if the on-site diagnosis points there.
