Weber Grill Replacement Parts: How to Find the Right Burner, Flavorizer Bars & Igniter for Your Spirit, Genesis & Summit Series
Why Identifying Your Weber Model Matters First
Weber has been the most recognized name in gas grills for decades, and their parts ecosystem spans multiple generations of the same series. A Genesis II 300-series uses different burners than a Genesis E-330, and a Spirit E-210 from 2015 differs from a Spirit II E-210. Before ordering any replacement part, locate the model number on your grill's owner label — typically found on the back of the control panel, inside the cabinet door, or on the rear panel. This small step saves you from ordering the wrong part and getting your grill back in action faster.
Burner Tubes: The Heart of Your Weber Grill
Weber's burner tubes are the most commonly replaced component. Over time, they corrode, develop rust holes, or the gas ports become clogged, leading to uneven heating and flare-ups. Weber grills use either standard 304 stainless steel burners or the proprietary Weber GS4 (Grill System 4) burners, depending on the series.
Genesis Series Burners (E/S-310, E/S-320, E-330)
The Genesis line uses three main burner tubes. The Genesis II and Genesis II LX models (2016-2020) use GS4 burners made of 304 stainless steel, which offer a 10-year warranty against rust-through. Older Genesis models (pre-2016) use the standard 304 stainless steel burners — both are premium-grade but the GS4 design features a larger burner diameter and wider gas ports for better flame distribution. If you're upgrading an older Genesis, the GS4 burner sets are backward-compatible with many pre-2016 frames.
Spirit Series Burners (E-210, E-310, SP-210, SP-310)
Spirit grills typically use two burners (E-210/SP-210) or three burners (E-310/SP-310). The Spirit II series (2017+) also uses the GS4 burner system. The Spirit burners are more compact than Genesis burners and are not interchangeable between series. Key model numbers to match: Spirit E-210 uses burner part 9930; Spirit E-310 uses burners 9931 (left) and 9932 (right + center). All are constructed from 304 stainless steel for maximum corrosion resistance.
Summit Series Burners (S-420, S-440, S-460, S-470, S-670)
Summit grills are the premium tier and use 4 to 6 burner tubes depending on the configuration. The Summit S-670 uses six burners, while the S-420 uses four. Summit burners are also 304 stainless steel but are physically longer and wider than Genesis/Spirit burners. They also include a dedicated sear station burner on models with the Tuck-Away sear burner feature. Summit burner part numbers start with 7620 series — always verify by your specific model number.
Flavorizer Bars vs. Heat Plates: What Your Weber Needs
Weber uses the trademarked term "Flavorizer Bars" — angled stainless steel bars that sit above the burners and below the cooking grate. They are not ceramic heat plates or lava rocks. Their job is to catch drippings, vaporize them into smoke, and protect the burners from grease buildup. Over time, Flavorizer bars warp and corrode, especially the center sections that take the most heat.
Genesis Flavorizer Bars
Genesis II and Genesis II LX models use a 3-piece Flavorizer bar set (part numbers 7600, 7601, 7602). Older Genesis models (pre-2016) use a different 3-piece set (6650, 6651, 6652). The newer GS4 bars are slightly wider and made of heavier-gauge 304 stainless steel, providing better heat distribution and longer life. If your bars are more than 3 years old and show signs of warping or rust pitting, replacement will restore even heat and reduce flare-ups.
Spirit Flavorizer Bars
Spirit II series uses 2-piece Flavorizer bar sets (7605 for left, 7606 for right) on 2-burner models and 3-piece sets on 3-burner models. Original Spirit series (pre-2017) uses a different bar shape (6653 left, 6654 right). Ensure you select the correct generation — the mounting tabs differ between Spirit and Spirit II.
Summit Flavorizer Bars
Summit grills use a multi-piece Flavorizer bar system that matches their burner count. The Summit S-670 uses 6 bars, while the S-420 uses 4. Summit bars are the longest in Weber's lineup and are made of heavy-gauge 304 stainless steel. Part numbers in the 7620 series apply to most Summit models.
Igniter Troubleshooting & Replacement
Weber igniters generally fail for one of three reasons: the battery is dead (electronic models), the ceramic electrode is cracked, or the collector box has corroded. Weber's electronic ignition (Crossover Ignition System) uses a single igniter that sparks all burners through a crossover channel. This is a common failure point on Genesis and Spirit models.
Genesis & Spirit Electronic Igniter
The standard Genesis and Spirit electronic igniter module (part 7517) is a straightforward replacement. You remove the control panel, unclip the old module, and snap in the new one. The igniter delivers a spark to the crossover tube, which then lights all burners. If you hear no clicking at all, the igniter module has likely failed. If you hear clicking but no flame, check the electrode gap (should be 3/16" from the crossover tube) and clean any grease buildup.
Summit Igniter System
Summit models use a more robust igniter system with dual electrodes. The Summit igniter kit (part 8170) includes the module, wiring, and electrodes. Due to the larger number of burners, Summit igniters sometimes fail on the sear burner side first — if only the sear burner won't light, the electrode on that side is the likely culprit.
Quick Reference: Weber Model Numbers & Their Parts
| Series | Model Examples | Burner Count | Burner Material | Flavorizer Bars |
|---|---|---|---|---|
| Spirit (original) | E-210, E-310 | 2-3 | 304 Stainless Steel | 6653/6654 |
| Spirit II | E-210, E-310 | 2-3 | GS4 304 Stainless Steel | 7605/7606 |
| Genesis (pre-2016) | E-310, S-310, E-330 | 3 | 304 Stainless Steel | 6650/6651/6652 |
| Genesis II | E-315, E-335, S-335 | 3 | GS4 304 Stainless Steel | 7600/7601/7602 |
| Genesis II LX | S-340, S-345 | 3+sear | GS4 304 Stainless Steel | 7600/7601/7602 |
| Summit | S-420, S-440, S-670 | 4-6 | 304 Stainless Steel | 7620 series |
All Weber replacement parts we carry are made from 304 stainless steel — the industry standard for rust and corrosion resistance. Never settle for "stainless steel" without the 304 grade; cheaper alloys will rust within a season.
Frequently Asked Questions
How do I know if my Weber burner needs replacing?
Look for visible rust holes, flaking metal, or a yellow/orange flame instead of a clean blue flame. If the flame is uneven across the burner or you hear popping sounds, the gas ports are likely clogged or corroded — time to replace.
Can I use Genesis burners on a Spirit grill?
No. Genesis and Spirit burners have different dimensions, gas manifold connections, and mounting brackets. Always match the burner to your specific series.
How often should I replace Flavorizer bars?
Every 2-3 years depending on usage. If you grill year-round, inspect them annually. Replace when you see significant warping, rust flakes falling onto the burners, or the gaps between bars have widened noticeably.
What is the difference between GS4 and standard Weber burners?
GS4 (Grill System 4) is Weber's fourth-generation burner system featuring larger diameter tubes, wider gas ports, and a 10-year rust-through warranty. Standard burners are also 304 stainless steel but have a narrower tube profile. GS4 burners are standard on Genesis II, Genesis II LX, and Spirit II models.
My igniter clicks but the grill won't light — what's wrong?
Check the electrode gap to the crossover tube (3/16"), clean any grease or debris off the electrode, and ensure the gas tank is full and the valve is open. If the spark is jumping elsewhere (to the grill body), the ceramic electrode is cracked and needs replacement.
Keep Your Weber Grilling at Its Best
Weber grills are built to last, but their burners, Flavorizer bars, and igniters are wear items that need periodic replacement. Whether you own a Spirit, Genesis, or Summit, using genuine-spec 304 stainless steel replacement parts ensures your grill heats evenly, avoids flare-ups, and stays in service for years.
