Weber Spirit Grill Parts: Complete Replacement Guide by Model

The #1 part that wears out on any gas grill. Weber Spirit burner tubes are stainless steel and typically last 5 to 10 years before corrosion opens up holes, warps the tube, or clogs the gas ports. Signs you need new burners: uneven flames, flames shooting up from the wrong places, yellow or orange flames instead of blue, or visible rust-through.

Replacement burner sets always come as a kit covering all tubes for your grill — don't replace just one. Weber OEM burner tube kits come with the correct crossover tube that connects them. Aftermarket kits from manufacturers like Hongso, BBQration, and Uniflasy are typically 40–60% cheaper than OEM and hold up well if you pick a stainless steel (304-grade) set, not plain steel.

Common burner tube kits:

• Weber Spirit I E-210/S-210: 2-tube kit
• Weber Spirit I E-310/S-310, E-320/S-320: 3-tube kit
• Weber Spirit II E-210/E-220: 2-tube kit (different dimensions from Spirit I)
• Weber Spirit II E-310/E-320/SP-335: 3-tube kit

Flavorizer bars sit above the burners and catch drippings, which then vaporize and add flavor back to the food. They also shield the burner tubes from grease, which extends burner life. Weber Spirits come with either porcelain-enameled steel (shorter-lived, coating chips and flakes) or stainless steel (longer-lived, doesn't flake).

Replace flavorizer bars when the coating is flaking off, they've warped, or they've rusted through. Most Spirit owners replace them every 3–5 years with porcelain, or every 7–10 years with stainless.

The two most common Weber Spirit flavorizer bar sizes:

• 22.5" bars (5-pack): fits Weber Spirit 200-series (Spirit I and Spirit II E-210/E-220)
• 25.5" bars (5-pack): fits Weber Spirit 300-series (Spirit I and Spirit II E-310/E-320/S-310/S-320) — also fits older Genesis Silver/Gold/Platinum B & C

Upgrading from porcelain to stainless on the same grill is one of the highest-impact cheap upgrades — stainless bars hold heat better, distribute vaporized drippings more evenly, and last more than twice as long.

Weber Spirit grates come in three materials. Replace them when food sticks consistently even after cleaning, when porcelain coating has chipped off and exposed bare iron (risk of rust in food), or when bars have warped.

• Porcelain-enameled cast iron (standard on most Spirits): great heat retention and sear marks, coating eventually chips
• Porcelain-enameled steel (lower-cost Spirits): lighter, faster to heat, shorter lifespan
• Stainless steel (some "S" models): easiest to clean, no coating to fail, slightly less searing heat

The grate sizes to know:

• Spirit 200-series: two grates, each approx. 17.3" × 11.8"
• Spirit 300-series: two grates, each approx. 17.3" × 11.8" (slightly different arrangement)
• Spirit II E-310 GS4 (2018+): uses redesigned grates — check model year before ordering

Switching from porcelain-coated cast iron to porcelain-coated steel is a common downgrade mistake. If you loved the sear marks on your old grill, stay on cast iron or go to stainless — not cheap coated steel.

Weber Spirit ignition has three failure points: the battery module (for electronic ignition models), the igniter electrode at each burner, and the wiring that connects them. When the grill clicks but doesn't spark, or sparks but doesn't light, the igniter is almost always the problem.

Diagnosing in order of likelihood and cost:

1. Battery dead — replace it (AA for most Spirit II, AAA for older). Fixes roughly half of "my Spirit won't light" complaints.
2. Loose wires — reseat the connections under the control panel. Free.
3. Igniter electrode corroded — replace the electrode (a few dollars each). Visible rust or burnt tip is the tell.
4. Push-button module failed — replace the full kit.

Full igniter kits include the button/battery module, all electrodes, and the wiring harness — typically $20–$40 OEM, $10–$20 aftermarket.

Some Weber Spirit models use heat deflectors instead of flavorizer bars (particularly older Spirit I units and certain aftermarket conversions). If your grill has V-shaped metal plates above the burners with grease-collecting channels, you have flavorizer bars. If it has flat or slightly angled plates without channels, those are heat deflectors.

Heat deflectors are simpler and cheaper to replace than flavorizer bars and typically outlast them. Check thickness when buying aftermarket — a thin heat plate (under 0.8mm) will warp after a few dozen cooks.

The disposable aluminum drip pan slides into a grease tray under the grill. Replace the aluminum drip pan every 3–4 cooks to prevent grease fires. The grease tray itself rarely fails but can rust through at the corners after 5+ years — this is a cheap OEM part to replace.

Weber Spirits use a low-pressure LP regulator and hose assembly. Replace every 5–10 years, or sooner if you notice: propane smell at connections, the regulator "trips" into bypass mode frequently, visible cracks in the hose, or the grill suddenly stops producing its usual heat output on high.

Cosmetic replacement. Broken, melted, or missing knobs. Most Spirit knobs are universal within a generation, but 2025+ Reimagined Spirits use a completely different knob design.
