WB28K10222 GE Oven Burner Cap 15K is a replacement burner cap for GE gas ovens and ranges, āidentified by the WB28K10222 part number with aā 15K variant designation.The component is a heat-resistant metal cap thatā sits on the burner head and covers the burner ā£ports; it is a mechanical part of the burner assembly rather than an active electronic or gas-regulating device. Its form, fit and materialā£ are selected to withstand repeated high-temperature cycles and to alignā£ theā flame pattern produced by the burner ports.
Inside the appliance,the burner ācap interfaces directly with the burner base,burner ports,and the ignition system to influence flame shape,combustion stability and heat distribution across the oven cavity.It affects primary ā¢air mixing at the venturi and helps protect the burner ports from spills and debris that ā¢canā obstruct flow or cause irregular flames. Because the cap determines whereā flame impinges and how heat radiates from the burner, its condition can impact ignition timing, combustion quality ā(color andā lift āof ā¤the ā¢flame)and even temperature uniformity during ā¢cooking.
In this article you will learn the functional purpose of the WB28K10222 burner cap and the meaning of the 15Kā designationā as itā relates to fit and heat class; how to determine compatibility with specific GE oven and range models; ācommon symptoms of cap-related failure (uneven or yellow flames, delayed ignition, āsootingor heat distribution issues); basic troubleshootingā steps to inspect and diagnose cap problems; and practical replacement considerations such asā¢ correct sizing, material and seating, verification after installationand safety precautions to observe when working on the gas system.

Function and role ofā the Oven Burner Cap in Gas Range Operation
The WB28K10222 GE Oven Burner Cap 15K sits directly over the burner head and performs two linked mechanical and āthermal functions: it ā¤shapes ā¤the burner’s flame envelope for uniform heat distribution āacross the oven cavityand it protects theā burner ports from direct spillage and mechanical damage. As a passive component, the cap’s ā£diameter, thicknessand seating surface determine ā£the flame pattern and the effective venting of primary air; a cap designed for a nominal 15K burner will align the flame to match the orifice sizeā¢ and manifold pressure used with thatā£ rating.While the cap itself doseā not change gas composition,technicians must fit the correct cap ā£to āthe matching burner head,orifice and regulator settings-an otherwise correct part on a mismatched assembly can produce long,unstable flames,incomplete combustion,or reducedā¢ heat delivery.
In service, the burner cap’sā condition correlates directly with observable burner behavior andā¢ service actions: a nicked, warped or ā£contaminated cap commonly causes yellow or lifting flames, localized overheatingor soot buildupā on oven racks. Simple maintenance steps-remove deposits,verify the cap seats flat against the āburner flange,and confirm port clearances-often restoreā proper operation without replacing upstreamā components. āPractical checks and indicators for troubleshooting:
- Visual: flat seating surface,no warping,clean āport faces.
- Flame pattern: even blue ā¢envelope with a small inner ā¢cone; yellow tips indicate port blockage or air/gas mismatch.
- Compatibility: verifyā¤ part geometry and 15K nominal rating against the burner head and gas type (natural vs LP) before replacement.

How the ā¢WB28K10222 GE Ovenā Burner Cap 15K Operates Within the Burnerā Assembly andā£ Gas Delivery System
the WB28K10222ā GE Oven Burner Cap 15K is a shallow metal cap that sits directly over the burner headā£ andā ports to shape and stabilize the burner flame within the oven’s combustion chamber.In operation it controls the final geometry of the flameā by constraining where gas-air jets emerge, shielding the ports from debris and radiating heat back intoā£ theā£ burner area; these effects influence combustionā¤ efficiency, flame stabilityā and the thermal ā¤profile delivered toā the oven cavity. Because the cap’s diameter, seat geometry and heat capacity ādirectly affect how the gas jets mix with primary air, theā¢ WB28K10222 cap mustā¢ match the burner base and orifice sizing specified for a 15K-rated burner assemblyā¤ to maintain expected output and āsafeā¤ combustion ā¢behavior.In practice, a properly seated capā producesā a short, even blue flame āacross the port array; a missing, warped or mismatchedā¢ cap commonly causes lifting or yellowing flames, soot, slow ignitionorā uneven cooking.
- Primary functions: protect ports, shape flame patternand radiate heat for even distribution.
- Failure symptoms: asymmetric flame, sooting, delayed ignition, temperature inconsistency across racks.
- Compatibility considerations: correct seat diameter, port alignmentand nominal 15K rating for matching manifold/orifice.
Within the gas delivery system the burner cap is passive but ā¢critical: gas is metered at the orifice and introduced into āthe burner head where primary air is entrained; the cap thenā¢ determines ā¢local flowā£ separation and flame attachment points,which āgovern flame lift,heat transfer ā¤and oxygen availability at each port. Materials and surface ācondition matter-pitted or coated surfaces change ālocal heat flux and can alter combustionā¤ characteristics-so technicians often inspect the cap for deformation ā¤and clean the surroundingā¢ portsā ratherā than change gas pressuresā£ or orifices first. For troubleshooting or replacement, verify āthat the cap aligns with the burner head, that the orificeā and manifold ā¤areā the intended ā¤size for a 15K assemblyand confirm correct flame shape (short, steady blue flames) under normal operating conditions to ensure the assembly is functioning asā designed.

Common Failure Symptoms and Diagnostic Tests for Burner Cap Malfunction
The WB28K10222 GE Oven Burner Cap 15K ā functions as the interface between the ā£gas port and the flame, centering and shaping theā burner jets so the oven cavity receives an even heat profile. The cap’s geometry and seatingā£ control primary-air mixing and flame distribution; a 15K designation indicates it is matched to a burner/valve assembly rated for roughly 15,000 BTU, so mismatched caps or slight warping can āchange burn characteristics and impair combustion efficiency. Technicians will see ā¤that a properly seated cap produces short, steady, blue inner cones with minimal yellow tipping,ā¢ while a deformed or carbon-clogged cap produces elongated flames, sootor localized hot spots in the oven chamber-symptoms that directly affect bake uniformity, broil performanceand ā£safety margins around seals and sensors.
Diagnostic work combines visual,ā¤ functionalā and pressure-related checks to isolate cap-related failures from ignitor or manifold problems. Start withā£ a close visual inspection for cracks,warpage,or carbon buildup and confirm theā¤ cap seats flushā on the burner body; thenā perform a flame-pattern test and compare against known-good behavior. For confirmation, swap the suspect ācap with a known-goodā WB28K10222 or ā¤measureā manifold pressure with a manometer to verify valve output matches manufacturer specification. Measure electrode gap and observe spark stability when appropriate; if flame irregularities persist afterā¢ cleaning and correct seating, replace the cap to restore designed combustion geometry.
- Common symptoms: uneven flame pattern, yellow tipping or soot, delayed ignition, localized overheating or cold spots.
- Speedy checks: cap seating/fit, visible deposits, spark presenceand swapping withā¢ a verified cap.
| Test | Expectedā¤ result |
|---|---|
| Visual fit and seating | Cap seats flush, no visible warpageā¤ or heavy carbon that blocks ports |
| Flame pattern test | Multiple short blue cones, even distributionā around cap perimeter |
| Manometer pressure check | Manifold pressure within OEM tolerance for 15K burner rating |
| Swap with known-good cap | Symptoms resolve if cap was the root cause |
Compatibility Across GE Oven Models,ā¢ Replacement Considerationsand Installation Procedure for WB28K10222 GE Ovenā¢ Burner Cap 15K
WB28K10222 GEā¤ Oven Burner Cap 15K serves as the contact surface and flame-shaping elementā for a 15,000 BTU ovenā¢ burner assembly. Theā cap seats over the āburner head to protect the burner ports, distribute the flame envelope evenly across the cooking āsurfaceand moderate heat transferā to the surrounding panā¤ and grate. Compatibility depends on mechanical fit and thermal rating: the cap must match the burner head diameter andā port pattern, sit flush without rockingand be used with a valve/orifice combination sized for a 15K burner. Technicians verify fit ā£by confirming the OEM part number, measuring cap diameter and locating tabs or alignment slotsand comparing port alignment to the burner head; an incorrectly sized or warped cap will produce uneven flames, higher COor slower recovery times.
- Measure outer ā£diameter and check for alignment tabs āto confirm mechanical fit.
- Inspect cap material and finish ā¢for warping, pittingor cracked enamel that affect sealing and flame shape.
- Cross-reference the part number with the oven model or service ā¢manual rather āthan relying on visual similarity alone.
- Confirmā burnerā orifice/valve is rated for 15K BTU; ā¤a mismatched orifice will change flame height and combustion characteristics.
