GE Stove Repair in Toronto — Weak or yellow gas flame

• A lazy yellow flame on ONE GE/Hotpoint/Profile sealed surface burner is, before any part, a clogged-port and burner-cap/head problem -- GE's own yellow-flame guidance is that the colour is an improper air-to-gas ratio (incomplete combustion), and on a sealed-burner top the air shutter is NOT adjustable, so the cure is clearing debris, not 'opening the air.' A boil-over carbonizes the small ports on the GE medium surface burner head WB16K10055 (AP3872881 / PS1020327), or the cap is rotated off its locating notch after cleaning, so the air/gas mix exits unevenly and burns yellow. We lift the cap, clear the ports with a fine wire (never a wooden toothpick), brush the head, and reseat the matched cap flat on its WB16K10055 head first -- this $0 fix corrects a large share of single-burner yellow-flame calls and keeps us from selling an orifice the range never needed.
• The single most common confirmed weak/yellow-flame fault is a gas-type/orifice mismatch -- a GE range left on its factory natural-gas surface orifices after an LP (propane) install, or LP spuds run on natural gas. GE ships the surface-burner LP conversion as the 4-spud brass kit WB28K10556 (AP4368229 / PS2345630; replaces 1469119 / AH2345630 / WB28K10161), whose orifices have a SMALLER bore for LP's higher pressure; the matching single-burner medium NG-to-LP spud is WB28K10023 (PS240683, the '.89mm' orifice, removed with a 9/32-inch socket). When the orifice bore and regulator pressure don't match the supplied gas the burner runs lazy and yellow even with a healthy electrode (WB02X10822) and a good spark module (WB13T10076). This is a TSSA-certified gas-fitter orifice-and-regulator correction, not a blind parts-swap, and we verify the spud matches the gas type before condemning any ignition part.
• Weak, yellow flame across ALL burners at once -- not one position -- points upstream to manifold gas pressure rather than any single orifice or cap. The GE manifold gas pressure regulator WB19K10018 (AP3872498; replaces 1166924 / AH1021579 / PS1021579) limits incoming supply to the burner manifold and carries a gas-type setting: per GE's install spec the regulator is set to ~4 inches water column for natural gas and ~10 inches WC after LP conversion, with inlet supply required between 5-13 inches WC (NG) or 10-13 inches WC (LP) and at least 1 inch above the operating pressure. A regulator left on the wrong gas setting, a stuck/failed regulator, or an undersized supply line starves every burner so they all burn lazy and yellow together. We meter delivered manifold pressure and confirm the WB19K10018 gas-type setting before condemning it -- a whole-cooktop yellow flame is a pressure story, a single yellow burner is an orifice/cap story.
• One burner that runs yellow and weak while its siblings burn crisp blue is a partially clogged or wrong orifice/spud on that single position -- grease, carbon, or debris narrowing the jet at the orifice holder WB02K10361 (the surface-burner orifice holder, removed with a 5/8-inch retaining nut), which seats the spud that meters gas into that burner. Because the rest of the burners are correct, the regulator and gas type are proven fine, so we pull and clear (or replace) just that single spud/holder rather than re-orificing the whole range. On a GE NG-to-LP unit the single replacement spud is the WB28K10023 (.89mm) seated in the WB02K10361 holder.
• A yellow flame that appeared right after a cleaning, boil-over, or cap re-seat is usually a seating/secondary-air fault, not a gas-mix fault: a GE burner cap rotated off its locating notch, cocked, or swapped onto the wrong-size head leaves the flame ports partly shadowed and chokes the secondary air so the flame tips yellow. We verify each cap matches and locks square to its own WB16K10055 head and sits flat, clear the ports, and confirm the flame snaps back to blue before quoting any hardware -- many of these calls clear with zero parts. GE's own note that a clean burner can still take several clicks to light reminds us to check cap fit before condemning an electrical part.
• A unit that has burned slightly yellow at the LOW/simmer setting since an LP install is the conversion math, not a clog: LP requires the smaller-bore conversion spuds (WB28K10556 kit / WB28K10023 single) AND the regulator flipped to the ~10-inch WC LP setting -- if the cooktop spuds were swapped but the WB19K10018 regulator was left on the 4-inch NG setting (or vice-versa), the burner runs rich and lazy. Note GE guidance that a slight yellow tipping on the outer cone can be normal on propane; we confirm the flame is genuinely weak/yellow through its body, then check that BOTH the orifice spud and the regulator setting were converted to the same gas before touching parts.
• A yellow, sooting flame at the OVEN burner (not the cooktop) after a conversion points to the oven orifice, a separate spud from the surface spuds. Owners who converted the cooktop with the WB28K10556 surface kit but missed the oven burner orifice get a yellow, sooting bake/broil flame while the cooktop looks right. We confirm which burner system is actually yellow first, and on a 'won't fully light or burns yellow' GE gas oven we also verify the glow-bar igniter WB13K21 (AP2020569) is drawing 3.3-3.6 A -- a weak igniter that under-opens the safety valve gives a small, starved oven flame -- so we separate an oven-orifice gas-mix fault from a weak-igniter heating fault rather than chasing the cooktop spuds.

GE weak or yellow gas flame in Toronto — the local specifics

• The recurring GE-in-Toronto weak-yellow-flame pattern is two-sided: single-burner yellow on a city natural-gas range is almost always a clogged port or a cap knocked off its notch after a clean -- a no-parts or burner-head (WB16K10055) clear -- while a whole-cooktop lazy-yellow GE that follows a move, a propane-property install, or a botched conversion is a gas-type/orifice and regulator-setting mismatch (NG spuds on LP or the WB19K10018 left on the wrong WC setting). We see the conversion-mismatch version disproportionately on units relocated between Toronto NG homes and LP cottage/rural properties.
• We carry the GE surface-burner consumables to these calls: spare WB16K10055 burner heads and matched caps, WB02X10822 electrodes (to rule the ignition side out), the WB02K10361 orifice holder, and the WB28K10556 LP conversion spud kit plus single WB28K10023 (.89mm) orifices, with a manometer for manifold pressure and the WB19K10018 regulator available to order when a whole-cooktop pressure fault is confirmed -- all NG/LP work performed by a TSSA-certified gas fitter.
