WB28K10222 GE Oven Burner Cap 15K is a specific burner cap assembly for GE gas ovens and ranges; it is a replaceable metal component that sits over the burner head too protect the burner ports,help direct the flame pattern,and influence heat distribution within the oven cavity. As a hardware element, the cap provides a defined surface for the flame to form against and shields the internal burner geometry from food debris and corrosion that can alter combustion performance.
Inside the appliance the burner cap interfaces directly with the burner head, the gas orifice/manifold, and the igniter or pilot assembly, and it indirectly affects the oven’s temperature control and safety systems by influencing combustion stability and heat transfer. Proper seating and dimensional fit are vital to maintain correct port alignment and gap clearances; misalignment, warping, or buildup on the cap can cause altered flame shape, incomplete combustion (sooting or yellow flame), delayed ignition, or uneven oven temperatures, which in turn can trigger diagnostic faults or lead to accelerated wear of the igniter and valve components.
In the following article readers will find a technical overview of the WB28K10222 part’s function, guidance on verifying compatibility (including how the 15K variant relates to application and fit), common failure symptoms to watch for, diagnostic checks and basic troubleshooting steps, and practical considerations for replacement such as material, dimensional inspection, and post-replacement verification. The details is presented to help technicians, engineers, and appliance owners determine whether the cap is the source of a problem and to plan an appropriate, safe repair or replacement strategy.

Function and Role of the Oven Burner Cap in Gas Combustion and Heat Distribution
The WB28K10222 GE Oven Burner Cap 15K is a precision cap that sits directly over the burner head to shape the flame, protect the burner ports, and stabilize the air‑fuel mixture for consistent combustion. Its 15K designation reflects the designed flow capacity and port geometry; that dimensioning controls the flame spread and heat flux across the oven floor and baking surface. Because the cap determines how the flame is distributed and how primary air is entrained at each port, using a cap with the wrong port pattern or BTU rating will alter combustion characteristics, producing uneven heat patterns, yellow tipping or soot, and longer recovery times during cyclic heating.
During operation the cap provides a mechanical seat that maintains consistent port alignment and thermal mass that evens transient heat spikes from ignition and burner cycling. Physical damage, warping, or debris under the cap changes the clearance to the burner head, which in turn causes lift, noise, poor ignition, or localized hot and cold spots; these symptoms are diagnostic of cap mismatches or deterioration. For repair and compatibility checks, verify the part number and BTU rating, confirm correct orifice/injector sizing for natural versus LP gas, and ensure the cap seats flat on the burner bowl to restore intended heat distribution and combustion stability.
- normal function: stabilizes flame pattern and protects ports
- Failure signs: yellow flame, soot, flame lift, uneven baking
- Compatibility check: match part number and BTU/port geometry

How the WB28K10222 GE Oven Burner Cap 15K Integrates with the Burner Assembly and Ignition System
The WB28K10222 GE Oven Burner Cap 15K is the OEM cap that locates directly on the burner head and establishes the geometry of the primary gas jet and flame envelope. By centering and partially enclosing the burner ports, the cap controls the air/fuel mixing region and stabilizes the flame pattern produced at the burner’s nominal 15,000 BTU output. In the ignition sequence the cap also shields and positions the spark electrode or igniter tip so that the spark-to-flame gap and flame contact area remain consistent; a cap that is warped, corroded, or improperly seated will change that gap and commonly produces intermittent ignition, delayed light-off, or unstable flame shape.
Mechanically the cap must match the burner head profile to maintain correct port alignment and thermal mass; many replacement issues arise when a non‑matching cap alters flow characteristics or fails to protect the electrode from combustion deposits. Technicians should check for carbon buildup,enamel damage,and correct seating before assuming an igniter failure – cleaning or reseating the cap often restores normal flame distribution and reliable ignition. In ovens with flame-sensing controls, a shifted flame pattern caused by an incorrect cap can reduce flame current and trigger safety lockouts, so replacement with the correct-cap geometry is a practical requirement rather than a cosmetic choice.

Common Failure Symptoms and Diagnostic Indicators for a Degraded Burner Cap
The WB28K10222 GE Oven Burner Cap 15K is the mating surface that centers the gas jet,stabilizes the flame,and shapes the primary combustion zone on a 15,000 BTU surface burner. Proper function depends on precise seating against the burner head and correct clearance to the burner ports: any warping, heavy carbon buildup, or mismatch in cap geometry changes the air-fuel mixing characteristics at the burner mouth. Technicians should understand that the cap does not control gas flow volume (the orifice does), but it influences secondary flow patterns and flame containment; symptoms that appear on one burner but disappear when that cap is swapped to another burner indicate the cap or its seating as the root cause rather than the valve or orifice.
- Uneven or slow heating: one zone of a pan heats noticeably slower than others – swap the cap with an adjacent working burner to see if the behavior follows the cap.
- yellow tipping, soot, or black deposit formation: indicates rich combustion caused by partial blockage or misalignment of the cap affecting primary air; inspect for carbon, crusted grease, or melted plastic.
- Flame lift, fluttering, or sustained popping on ignition: a lifted flame (several millimeters of visible separation from the burner mouth) or intermittent blowouts point to cap deformation or improper seating.
- Ignition delay or repeated clicks without stable flame: if the spark consistently lights surrounding gas but flame fails to stabilize until the cap is reseated or cleaned, the cap surface or seat alignment is suspect.
- Physical damage or corrosion: visible chips, cracks, or uneven underside surfaces that prevent full contact with the burner head.
Diagnosing a degraded burner cap is primarily visual and functional: inspect the cap-to-head interface for concentric contact, clean the underside with a brush and solvent to remove carbon, then verify flame geometry – a healthy burner shows a compact blue cone with minimal yellow tipping and stable height. Compatibility matters: replacing a damaged cap with a non‑matching geometry or a cap sized for a different BTU rating can recreate symptoms as the effective primary-air path changes; when in doubt, replace with the specified WB28K10222 unit and confirm correct orifice/head alignment.For field checks, swapping caps between burners, observing ignition behavior, and noting changes in cook times or flame shape provide reliable, low‑cost diagnostics before disassembly or parts replacement.

Replacement Considerations, Model Compatibility and Installation Procedure for WB28K10222
The WB28K10222 GE Oven burner Cap 15K is a stamped burner cap that sits directly over the burner head to shape the flame pattern, protect the burner ports from spatter and debris, and contribute to consistent air-fuel mixing for a burner class in the 15K range (approximately 15,000 BTU). The cap’s outer diameter, seating surface, and any alignment tabs determine whether it will correctly mate with a given burner ring and orifice; mismatched caps change primary air entrainment or lift the flame away from the desired ports, producing weak, yellow, or noisy flames. Technicians should compare the physical dimensions and mounting features of the replacement cap to the original part and confirm manifold pressure and orifice size are appropriate for a 15K-rated burner to ensure combustion stability after replacement.
Model compatibility requires verifying that the cap’s seating geometry matches the oven burner assembly rather than relying solely on model lists: several GE ranges share similar components but may use caps with different center-post profiles or vent clearances. For installation and initial verification, remove carbon and deposits from the burner head so the cap seats flat, restore gas and electrical power only after a visual fit check, and observe flame shape and color under typical load. If flames are unstable or exhibit excessive yellow tipping after fitment, re-check orifice size, manifold pressure, and alignment; if ignition problems persist, inspect the igniter/thermocouple clearance relative to the new cap seating as part of the diagnostic sequence.
- Installation checklist: shut off gas and power; remove grates and burner head debris; compare cap dimensions and orientation; seat new cap flat; restore gas and test for stable blue flame and proper ignition.

Q&A
What is the WB28K10222 (GE Oven Burner Cap 15K) and what does “15K” mean?
The WB28K10222 is a replacement burner cap for certain GE gas ranges/cooktops. The “15K” designation refers to the nominal burner output the cap is designed to sit on – roughly a 15,000 BTU burner head. The cap itself helps distribute the flame evenly over the cooking surface and protects the burner head ports.
How can I tell if WB28K10222 is the correct replacement for my range?
Confirm compatibility by checking your appliance model number against GE parts diagrams or the parts seller’s compatibility list. You can also compare the existing cap’s shape, diameter, and how it seats on the burner head. If in doubt, use the OEM part number printed in your owner’s manual or on the range parts sticker and verify with GE or an authorized parts dealer.
How do I replace the burner cap (safe step‑by‑step)?
Turn off the burner and allow everything to cool completely. Remove grates, lift off the old cap (it typically just lifts off – no screws), inspect and clean the burner head if needed, then seat the new cap flat and centered on the burner head. Replace the grates and test the burner by lighting it. If the cap resists seating, do not force it – check for debris or misalignment. If you smell gas or see large yellow flames, turn off and investigate before continued use.
How should I clean the WB28K10222 and what cleaners should I avoid?
Remove the cap and wash with warm soapy water and a soft brush or cloth to remove grease and food residue. Avoid harsh abrasive pads, wire brushes, oven cleaners or strong acids that can damage enamel or coatings. Rinse and dry completely before reinstalling. While some caps survive dishwashers,repeated dishwasher use can dull or chip coatings,so hand cleaning is recommended.
What symptoms mean the burner cap needs to be replaced?
Replace the cap if it is cracked,severely chipped or warped,has heavy corrosion,or the coating has flaked off. Operational symptoms include persistent uneven or lifting flames, frequent flame blowout, or yellow/orange flames that don’t correct after cleaning and reseating the cap. Those signs indicate the cap or burner components are affecting combustion.
Will replacing the burner cap change the burner’s BTU or combustion characteristics?
The cap influences flame shape and distribution but does not change the gas supply, orifice size, or regulator setting that determine BTU. If you need a different heat output or are converting between natural gas and LP, the orifice and possibly regulator must be changed – the cap alone won’t convert or re-rate the burner.
Is WB28K10222 an OEM part and can I use aftermarket alternatives?
WB28K10222 is a GE part number commonly sold as an OEM replacement. OEM parts guarantee fit and finish for the intended burners.Aftermarket caps may fit and be less expensive, but you should confirm dimensions, seating style, and material/coating before buying. When possible, use the OEM or a verified compatible part to avoid fitment and combustion issues.
Are there any safety precautions I should take when handling or replacing the burner cap?
Always ensure burners are cool and,if working on the oven or range internals,turn off gas supply and power. Do not use a damaged cap – it can cause improper combustion and carbon monoxide risk. after reassembly, light the burner and visually check for a steady blue flame; if flames are weak, yellow, or produce soot, stop use and have the range inspected by a qualified technician.
