WB28K10222 GE Oven Burner Cap 15K is a burner cap used on select GE oven burner assemblies; the “15K” designation commonly refers to a 15,000 BTU-class burner. The component is a small, machined metal cap that sits over the burner head and port assembly to protect and shape the gas flame, stabilize combustion, and provide a controlled interface between the burner base and the oven cavity.
Inside the appliance the burner cap interfaces directly with the burner head, igniter or spark module, and the oven’s gas valve/manifold. proper seating and alignment of the cap affect primary air flow, flame pattern, and port shielding, so the cap contributes to even heat delivery, efficient combustion, and prevention of flashback or sooting.The cap also helps protect the burner ports from food debris and corrosion; its material, surface finish, and fit tolerance will influence how the burner performs and how it responds to cleaning or mechanical wear.
In this article you will find a technical overview of the WB28K10222 GE Oven Burner Cap 15K, including how it functions within the burner system, how to determine compatibility with specific GE models, common failure symptoms (uneven or yellow flame, ignition problems, or heat distribution issues), diagnostic checks a technician can perform, and practical replacement considerations such as part fit, inspection for damage, and basic safety precautions to observe during service. The goal is to provide clear, usable information that supports accurate troubleshooting and safe replacement decisions without prescriptive step-by-step repair instructions in this introduction.

Function and Role of the Oven Burner Cap in Gas Flow,Flame Distribution,and Heat Output
The burner cap serves as the primary flow-shaping component on an oven burner head,and the WB28K10222 GE Oven Burner Cap 15K is an OEM exmaple sized to work with a 15,000 BTU oven burner. The cap mounts directly over the burner ports and modifies the local pressure and velocity field produced by the venturi and gas orifices; by intercepting and redistributing the gas jets it sets the flame anchoring points and the spread of the combustion zone. The cap geometry (diameter, height, port apertures or reliefs and seating tolerance) determines how the primary air mixes with the gas, which in turn affects flame stability, color, and the effective heat flux delivered to the oven cavity. Improper cap fit or damaged seating changes port backpressure and can produce lifting flames, yellow tipping, or localized hot and cold spots without any change in regulator pressure.
- Directs gas flow to establish consistent flame pattern across the burner head
- Stabilizes flame to prevent flashback and reduce noise
- Controls heat distribution and effective output by altering flame contact area
- Requires correct dimensions and seating to be compatible with the burner head
In practical service, technicians check the cap for flatness, correct orientation, and carbon fouling before adjusting regulators or replacing higher-level components; a worn or mismatched cap is a common root cause of uneven oven cooking. When replacing with a part such as WB28K10222 GE Oven Burner Cap 15K, compare physical dimensions and seating features rather than relying solely on part number – even small differences in cap thickness or port clearance change the combustion characteristics. The cap modifies the spatial distribution of heat but does not control gas supply pressure; if flames are weak despite a correctly installed cap, the next steps are to verify orifice sizing, manifold pressure, and primary-air shutter settings.

How the WB28K10222 GE Oven burner Cap 15K Integrates with the Burner Assembly, Orifice, and Manifold
WB28K10222 GE Oven Burner Cap 15K is a passive combustion component that mounts on the burner head and conditions the flame produced by the orifice and manifold pressure. The cap does not regulate gas flow; instead it shapes the primary-air/gas mixture at the burner ports, protects the port openings from debris, and stabilizes the flame pattern so heat is delivered evenly to the oven cavity. The “15K” designation indicates the burner’s nominal output (about 15,000 BTU) and implies a specific orifice size and manifold pressure setting for correct combustion; altering the orifice size or manifold pressure without using the matching cap geometry changes the primary air entrainment and can produce lifting flames, yellow tips, or incomplete combustion.
For practical service, confirm that the cap seats flush on the burner head and that the port alignment matches the orifice pattern before declaring other faults. when replacing or converting fuel types,match the WB28K10222 GE Oven Burner Cap 15K to the correct orifice and adjust manifold/regulator pressure to the appliance specification; failure to do so leads to soot,uneven heat distribution,or delayed ignition. Simple checks-visual flame inspection, port cleaning, and verification of orifice part number and manifold pressure-resolve moast compatibility issues and help ensure predictable oven performance.
- Common symptoms of cap/orifice/manifold mismatch: yellow flames, soot buildup, uneven oven temperature, delayed ignition.
- Installation checklist: verify cap seating, confirm orifice size for fuel type, measure manifold pressure, clean burner ports.

| Function | Shapes flame, protects ports, stabilizes combustion (no direct flow regulation) |
| Typical material | Stamped steel with heat-resistant coating or enamel; geometry must match burner head |
Common Failure Symptoms of oven Burner Caps: Uneven Flame, Ignition Delays, and Heat Variance
The WB28K10222 GE Oven Burner Cap 15K is a metal cap that seats over the burner head to protect the burner ports and to shape the gas flow and flame pattern for a 15K-sized burner. Its primary functions are to center the flame, maintain consistent primary air entrainment for correct air‑to‑gas ratio, and shield the burner ports from spills and carbon buildup. Compatibility is persistent by cap diameter and seating geometry rather than the part label alone, so technicians should confirm hub dimensions and model fit before replacing a cap; an incorrectly sized cap can alter combustion characteristics even if it physically fits the surface ring.
Uneven flame, ignition delays, and heat variance typically indicate altered gas flow or compromised port geometry on the burner cap rather than an electronic failure of the control system. Common causes include port blockage from soot or food residue, warping or corrosion that changes the cap-to-burner gap, and cap misalignment that shifts the primary air intake; each of these changes the local stoichiometry and can produce lifted flames, yellow tipping, intermittent ignition, or localized hot/cold spots. Practical diagnostic steps include a visual inspection and cleaning of ports, swapping the cap with an adjacent burner to isolate the fault, checking for flat seating with a straightedge, and observing spark timing-if symptoms follow the cap after a swap, replacement is warranted.
- Uneven flame – one-sided height or lifting; frequently enough due to blocked ports or a warped cap affecting gas distribution.
- Ignition delays – spark present but late or intermittent light; may result from altered port geometry causing poor mixture or from residual moisture/carbon disrupting ignition propagation.
- Heat variance – inability to reach set temperature or hot spots; can indicate partial port occlusion or degraded thermal conduction from a damaged cap.
| Item | Description |
|---|---|
| Function | Shapes flame, protects ports, and helps maintain correct air‑to‑gas mixture for stable combustion. |
| Diagnostic check | Inspect/clean ports, verify cap flatness and seating, swap with adjacent cap to confirm cap vs. valve/igniter fault. |
compatibility and Supported Appliance Models for the WB28K10222 GE Oven Burner cap 15K
The WB28K10222 GE Oven Burner Cap 15K functions as the protective and performance-critical cover that sits over the oven burner head. It helps shape the burner flame, stabilizes combustion across the burner ring, and protects the burner ports and igniter from direct contact with food debris and spatter. Compatibility with a specific oven depends primarily on burner geometry (cap outer diameter, recess depth, and central mounting/post interface), the intended BTU rating (15,000 BTU configuration), and whether the oven uses a sealed burner assembly or a removable cap style; the cap itself does not change valve sizing or gas pressure, so it must match the physical burner head and igniter position to reproduce the correct flame pattern and heat distribution.
Technicians should confirm fit by comparing physical dimensions and mounting details against the existing cap and the appliance parts diagram rather than relying solely on model lists; manny GE freestanding, slide-in, and built-in gas ovens that employ a 15K oven burner will accept this cap if the mounting and port alignment match. Practical compatibility checks include ensuring the cap sits flush without rocking, that the igniter orifice remains unobstructed, and that flame shape and color are correct after installation; replacing a damaged cap with WB28K10222 GE Oven Burner Cap 15K commonly resolves uneven baking or localized overheating when misalignment or erosion of the original cap is the root cause.
- Verify outer diameter and recess depth against the old cap.
- Confirm central mounting/post interface and hole alignment with igniter.
- Check flame pattern and stability after installation; adjust if flame impinges on cap.

Replacement Considerations and Installation Procedure for Oven Burner Caps, Torque and seal Requirements
WB28K10222 GE Oven Burner Cap 15K is a precision-formed cap that locates over the burner head to shape the flame and protect the burner ports from spatter and debris. The ”15K” designation corresponds to a burner sized for approximately 15,000 BTU input; using a cap designed for that rating preserves the intended flame envelope and heat distribution. A cap that is warped, improperly seated, or from an incompatible model will alter the air‑fuel mixing at the port tips, producing uneven flames, offset heat, and accelerated burner corrosion.Technicians should verify physical fit, port alignment, and that the cap contacts the burner base uniformly across its seating surface to retain original combustion characteristics.
- Shut off gas/electric supply and remove grates; lift cap straight off the burner head.
- Inspect mating surfaces for carbon build-up, deformation, or damaged insulators; clean with non‑abrasive tools.
- If the cap uses a retaining screw or nut, torque fasteners to the low values specified below; over‑torquing can distort the cap and change flame pattern.
- Replace any high‑temperature gasket or ceramic insulator with equivalent material specified by the manufacturer before reassembly.
- After reassembly, check flame pattern and perform a gas leak test at fittings and connections.
Many GE oven burner caps are held by friction or a single fastener; when a fastener is present apply low torque to avoid compressive deformation-typically around 8-12 in·lb (0.9-1.4 N·m) for small machine screws used on burner assemblies. if the service manual specifies a different torque, follow the factory value.Seal requirements are limited to high‑temperature gasketing or ceramic insulators where the cap interfaces with the burner body; use materials rated for continuous exposure to oven temperatures (minimum 260°C / 500°F) and avoid general‑purpose silicone compounds that can outgas or degrade. validate service by observing stable, blue flames across the port span and confirming no leaks with a calibrated leak detector or approved soap test.

|---|---|
| Torque (fastener) | 8-12 in·lb (0.9-1.4 N·m) typical for small screws; follow OEM spec if provided |
| Seal/Insulator | High‑temperature gasket or ceramic; rated ≥260°C (500°F) |
| Compatibility | Designed for 15,000 BTU burner heads matching WB28K10222 dimensions and port pattern |
Troubleshooting and Diagnostics: Test Procedures, Measurement Points, and Root-Cause Isolation for Burner Cap Issues
The WB28K10222 GE Oven Burner Cap 15K is a machined metal cap that centrally controls flame shape and port sealing on a 15,000‑BTU oven burner head; it sits over the burner ring to direct the gas/air mixture so combustion is even and stable across the oven floor. Proper seating and dimensional compatibility with the burner crown are necessary for correct primary air entrainment and to avoid localized fuel-rich areas that produce yellow tips, soot, or hotspots.Technicians should treat the cap as a mechanical air/fuel geometry component rather than an electrical part: a mismatched or warped cap will change flame spread and heat patterns even when the gas valve and ignitor are functioning normally, and swapping caps between different BTU-rated burners can visibly alter combustion behavior and oven temperature uniformity.
Diagnostics combine visual inspection, flame observation, and measured verification against service specifications to isolate root cause. Start by lifting the cap to check port cleanliness and cap seating, observe flame color and distribution across several burner ports, and verify ignition behavior (spark or hot surface glow) at the electrode while noting any correlation to cap position. Use a manometer to confirm manifold/regulator pressure per the GE service manual and a multimeter or voltage probe to confirm ignition circuit activity; document readings and compare to spec to decide whether the cap, burner head, electrode alignment, or gas supply is at fault. Key measurement points:
- Flame color and pattern across the burner ring (even blue flame vs localized yellow)
- Cap seating and port blockage (visual/soot deposit check after removing cap)
- Ignition presence and timing at the electrode or hot surface ignitor
- Manifold/regulator pressure measured with a manometer
- Electrode gap and continuity checks with a multimeter

Q&A
What is the WB28K10222 GE Oven Burner Cap 15K?
The WB28K10222 is a replacement burner cap used on certain GE gas ranges. The cap sits on top of the burner head to shape and protect the flame ports. The ”15K” generally refers to the burner’s intended output class (about 15,000 BTU) and indicates it’s the higher-output surface burner in a range of burner sizes.
How do I know if this burner cap will fit my GE range?
Check your appliance model number (usually on the oven frame,behind the door,or on the back) and cross-reference it with GE parts lists or a reputable parts supplier. You can also compare the part number WB28K10222 to the part listed in your range’s exploded parts diagram. If you’re unsure, provide your full model number to a parts dealer or GE support to confirm compatibility.
Can I replace the WB28K10222 myself, or do I need a technician?
In most cases replacing a burner cap is a simple user task: ensure all controls are off and the burner is cool, remove the grate, lift off the old cap and set the new one in place. However, if the range has ignition problems, damaged burner heads, or if you detect a gas smell, stop and contact a qualified technician. Do not attempt any gas-line work yourself.
After installing a new cap the flame is uneven or yellow-what should I check?
Common causes include a misaligned or improperly seated cap,debris or food buildup blocking the ports,or a damaged burner head beneath the cap. Remove the cap, clean both cap and burner head, ensure the cap sits flush and centered, then test. If the flame remains yellow or unstable,it may indicate clogged ports,an ignition issue,or a gas pressure problem-contact a technician if cleaning and repositioning don’t fix it.
How should I clean and maintain the WB28K10222 burner cap?
Remove the cap when the range is cool. Clean with warm, soapy water and a soft brush or cloth to remove grease and food residue. Avoid harsh abrasives or steel wool that can damage enamel coatings. Rinse and dry thoroughly before reinstalling to prevent ignition problems. Do not use oven cleaners or submerge electrical components.
Is the burner cap the same as the burner head or do I need both?
The burner cap is the removable top piece that covers the burner head (the base with the gas ports). They are separate parts. If the burner head (base) is cracked, corroded, or clogged, replacing only the cap may not solve performance issues; both parts should be inspected and replaced if necessary.
Where can I buy an authentic WB28K10222 and what should I look for?
You can purchase the part from the official GE Parts website,authorized appliance parts retailers,or reputable online marketplaces. When buying, confirm the seller’s return policy and that the part number exactly matches WB28K10222. Genuine or OEM parts ensure correct fit, finish, and heat-resistant coating consistent with the original.
will installing this burner cap change my burner’s heat output or cooking performance?
A correct WB28K10222 cap restores the burner’s intended flame pattern and efficiency; it won’t change the BTU rating set by the orifice and regulator. Using an incorrect cap size or a damaged cap can alter flame shape,reduce efficiency,or cause yellow flames,so always replace with the proper cap for your specific burner (the one specified as 15K for that position).
In Summary
The WB28K10222 GE Oven Burner Cap 15K serves a focused but vital role in oven operation by properly directing and shaping the burner flame, protecting the burner head from spillage and debris, and helping to maintain consistent heat distribution across the cooking surface. When functioning as intended, this component contributes to reliable ignition, efficient combustion, and predictable cooking performance for compatible GE oven models.
Because symptoms such as uneven heating, irregular flame patterns, or ignition difficulties can result from a range of causes (including the igniter, gas valve, burner head, or supply issues), accurate diagnosis is essential before replacing parts. Verifying that the burner cap itself is the source of the problem prevents needless expense and reduces the likelihood of repeated service calls. Where diagnosis is inconclusive, or where gas system work is required, reliance on qualified service personnel and appropriate diagnostic procedures is advisable.
When replacement is necessary, selecting the correct WB28K10222 part and ensuring proper installation restores intended performance, supports safe operation, and helps maintain appliance efficiency. Timely, appropriate repair minimizes the risk of further component wear or safety concerns and preserves the oven’s operating reliability when carried out in accordance with manufacturer guidance or professional service standards.
