GE Stove Repair in Toronto — Knob not turning or igniting

• A knob that spins freely in your hand while the burner or element never changes is, on GE/Hotpoint/Profile/Cafe ranges, a cracked knob D-hole before it is ever a valve or switch fault. GE knobs press onto a D-shaped (flat-sided) stem; the plastic collar splits at that D over time so the knob turns but no longer grips the stem to rotate it. GE supplies the Cafe gas knob set as the WB03X32194 knob kit (genuine OEM, AP6837585 / PS12709871; the kit ships six knobs and supersedes the older single-knob numbers WB03X25889 and WB03T10320, also cross-referencing 4920893; fits CGP350 / CGP650 series). The legacy single Cafe stainless knob WB03X25889 is the superseded number that this kit now replaces -- both resolve to the same AP6837585 / PS12709871 -- so we order the WB03X32194 kit rather than chasing the discontinued single. The broader range/oven knob is WB03X24818 (PS11729081 / AP5989029; brushed-stainless, shared across GE / Hotpoint / Haier / Monogram / Cafe). We pull the knob and turn the bare stem with pliers first: if the stem moves and controls fine but the knob doesn't grip, it is a $10-$25 knob, not a valve or switch.
• A gas knob that physically WON'T turn (or turns hard and gritty) with the knob removed is a seized or corroded surface-burner valve stem, not the knob. Older GE gas ranges use aluminum valve stems that oxidize; green crust around the stem collar after years of spills and steam stiffens the valve so the knob jams or snaps its D-hole trying to force it. The GE round surface-burner valve is WB28K10578 (genuine OEM, AP4687971 / PS3491506 / 2134465; RepairClinic part-replacement guide #1262), which meters gas from simmer to high. We test the bare stem by hand: a stem that won't rotate, is gritty, or shows oxidation is a sealed gas valve that gets replaced under TSSA gas-fitter scope, never lubricated and left in service.
• On ELECTRIC GE coil and glass tops, a surface knob that turns but the burner never changes heat -- stuck cold, stuck on high, or no response across the dial -- is the infinite (surface element control) switch behind that knob, not the element. The knob mounts directly on the switch shaft; when the switch's internal contacts pit or weld, the dial moves but the heat doesn't follow. GE's 8-inch / 2,500W infinite switch is WB24T10025 (genuine OEM, AP2024072 / PS236750; replaces 769692; fits GE / Hotpoint / Kenmore), with the newer-platform surface-element control switch WB24X25013 (AP5999509 / PS11729102; replaces 4464832 / 191D4774P005; fits GE JB6 / JB7 / JB8 / JBS / JS6 / JS7). We read switch output as the knob is cycled low-to-high: no change in output to a good element isolates the switch as the failed part.
• A loose, wobbly, or free-spinning knob on an ELECTRIC top where even the bare metal shaft turns without resistance is a broken infinite-switch shaft, not a knob -- the knob mounts on that shaft, so when the switch's shaft shears or strips internally there is nothing for a new knob to grip. This fails the same WB24T10025 (8-inch / 2,500W; AP2024072 / PS236750, replaces 769692) or the WB24X25013 surface-element control switch (AP5999509 / PS11729102) as a stuck-heat fault. We confirm by gripping the bare shaft: if it spins with no detents and no heat change, a fresh knob won't fix it and the switch is replaced.
• A GE knob that drifts off its setting -- a gas flame that creeps up or down on its own, or an electric burner that won't hold low/simmer -- traces to worn detents in the control behind the knob, not the knob face. On gas, the WB28K10578 surface-burner valve loses its simmer/low-flame detent so the flame won't sit where the dial is set; on electric, the WB24T10025 / WB24X25013 infinite switch loses its click-stops so the burner cycles wrong for the marked setting. We verify the symptom follows the position (gas valve vs. electric switch) and replace the seated control rather than swapping a knob that is mechanically fine.
• On touch/electronic-control GE ranges (no mechanical dial), a 'knob not working' complaint is actually an oven or panel control encoder/UI fault, not a press-on knob -- these models carry the control on the board behind the panel. We separate this from the mechanical-knob platforms by knob feel and model/serial: a smooth dial with defined OFF/HIGH stops is a mechanical valve (gas WB28K10578) or infinite switch (electric WB24T10025 / WB24X25013) and gets a knob or switch; an endlessly-clicking encoder or a flat touch panel means the fault is on the control board, which we confirm by model/serial before quoting. This keeps a cheap knob/switch job from being mis-sold as a board, and a true board fault from being chased with knobs.
• A knob that fits poorly, falls off, or grips intermittently after a parts-store knob was installed is a fitment mismatch -- GE runs several stem profiles, so a generic or wrong-series knob slips on the D. GE's own kit WB03X32194 ships six knobs (five WB03X25889-style metal plus one WB03T10320-style) precisely because the same Cafe range mixes knob types across positions. We match each knob to its own stem by model/serial -- WB03X32194 (which supersedes the single WB03X25889) for Cafe gas, WB03X24818 for the GE / Hotpoint / Monogram range-knob platform -- rather than forcing a single universal knob that won't seat square on every post.

GE knob not turning or igniting in Toronto — the local specifics

• The recurring Toronto pattern on GE 'knob not working' calls is that the knob itself is the cheapest and most common culprit -- a cracked D-hole on the press-on knob spins free while the valve or switch behind it is perfectly fine, so the very first thing we do is pull the knob and turn the bare stem. On older GE gas ranges in the GTA's aging housing the second pattern is a seized/corroded surface-burner valve stem (green oxidation at the collar) that jams the knob or snaps its D forcing it; on GE electric tops it's an infinite switch whose shaft has worn or sheared so the knob spins with no detents and no heat change.
• We roll to these GE knob calls with the common GE knob numbers on the van -- the WB03X32194 Cafe knob kit (which supersedes the older single WB03X25889) and the WB03X24818 range knob -- plus the WB24T10025 and WB24X25013 infinite switches for electric tops, so a cracked-knob or worn-switch call is usually closed same-visit. The WB28K10578 gas surface-burner valve and any model-coded electronic encoder we confirm by model/serial off the rating plate first, and all gas-valve work is handled under TSSA gas-fitter scope.
