Your Gas Grill Is Dying. Now What?
You paid $400–$600 for a gas grill five to ten years ago. The igniter clicks but nothing happens. The burners have rust holes the size of dimes. The heat tents have disintegrated into flakes that end up on your burgers.
Here’s the question: do you drop $200–$300 on replacement parts, or shell out $500+ for a new grill?
I’ve been through this exact scenario with three different grills, and the answer depends entirely on what you own and what’s broken. Let me break it down with real part prices, real grill costs, and the actual math on cost-per-year — the only metric that matters if you’re thinking about this from a buy-it-for-life perspective.
The Four Parts That Actually Fail
Every gas grill has the same failure points. The fire box and lid? They’ll outlast you if they’re made from decent steel or cast aluminum. The cart? Fine. The side burner you’ve used exactly twice? Not the issue.
These are the parts that die:
1. Igniters ($15–$30 aftermarket, $45–$55 OEM)
The push-button or electronic igniter is the first thing to go, usually around years 3–5. Moisture kills them. Grease kills them. Time kills them. The good news: this is a $15 fix with an aftermarket kit, or about $50 if you buy genuine Weber parts. And honestly? You can light a grill with a long-reach lighter for $3. An igniter failure alone is never a reason to replace a grill.
2. Burner Tubes ($30–$55 aftermarket, $85–$95 OEM)
Stainless steel burner tubes rust from the inside out. Cheap grills use aluminized steel or thin stainless that fails in 3–4 years. Better grills (Weber, Napoleon) use heavier-gauge tubes that last 7–10+ years. When you see uneven flames — tall on one side, nothing on the other — the burner is shot. A set of three aftermarket burner tubes runs $30–$55 on Amazon. OEM Weber tubes for a Spirit or Genesis run $85–$95 direct from Weber’s parts site.
3. Heat Tents / Flavorizer Bars ($30–$50 aftermarket, $85–$95 OEM)
These sit between the burners and the grate. They vaporize drippings (that’s the flavor) and protect the burners from grease. Porcelain-coated steel ones last 3–5 years. Stainless steel lasts 5–8. When they rust through, you get flare-ups and hot spots. Aftermarket flavorizer bars for a Weber Spirit run about $30–$40. Genuine Weber bars run $85.
4. Cooking Grates ($40–$60 porcelain, $100–$155 stainless OEM)
Porcelain-enameled steel grates chip, rust, and warp. Cast iron grates crack if you look at them wrong (and also rust if not seasoned). Stainless steel rod grates are the BIFL choice — they can last 10+ years with basic cleaning. A replacement set runs $40–$60 for porcelain aftermarket, $100–$155 for genuine Weber stainless.
The Real Cost Breakdown: Repair vs Replace
Let’s run the numbers on three common scenarios. I’m using a Weber Spirit E-310 ($499 new) as the baseline because it’s the most common mid-range grill people are trying to save — and because Wirecutter, Serious Eats, and CNET all still recommend it as the best gas grill under $500.
Scenario 1: 5-Year-Old Grill, One Failed Part
Say your igniter died and one burner tube is rusted through. Everything else is fine.
- Igniter kit: $20 (aftermarket)
- Single burner tube: $15 (aftermarket) or $32 (OEM)
- Total repair: $35–$52
- New grill: $499
At $35–$52 in parts, you’d be insane to replace the grill. That repair buys you another 3–5 years easy. Cost per year: $7–$10 for the repair vs $83–$100/year for a new grill over 5 years.
Scenario 2: 7-Year-Old Grill, Full Parts Refresh
Your grill has had it. Burners are shot, flavorizer bars are flakes, grates are rusted, and the igniter gave up two summers ago. The fire box and lid are solid. This is the “do I just buy new?” moment.
- Burner tube set (3): $40 (aftermarket) / $95 (OEM)
- Flavorizer bars: $35 (aftermarket) / $86 (OEM)
- Cooking grates: $50 (aftermarket porcelain) / $151 (OEM stainless)
- Igniter kit: $20 (aftermarket) / $46 (OEM)
Total aftermarket refresh: ~$145
Total OEM Weber refresh: ~$378
New Weber Spirit E-310: ~$499
Even the all-OEM route at $378 is cheaper than new — and you get another 5–8 years out of the grill. The aftermarket route at $145 is a no-brainer. Cost per year over the next 7 years: $21 (aftermarket) / $54 (OEM) / $71 (new grill).

Scenario 3: 10-Year-Old Big-Box Grill (Nexgrill, Dyna-Glo, Char-Broil)
This is where it gets ugly. You paid $200–$300 at Home Depot or Lowe’s. The fire box is rusting at the seams. The lid has a visible gap when closed. Parts are hard to find because the model was discontinued three years ago.
Here’s the uncomfortable truth: most big-box grills under $300 are disposable by design. The steel is thin, the burners are aluminized (not stainless), and the manufacturer doesn’t stock parts past a few years. You might find aftermarket parts that “fit,” but the fire box itself is the problem.
If the fire box is rusting through, you can’t fix that. If the lid doesn’t seal, you’re burning propane and getting uneven heat forever. Replace it — but this time, buy something worth repairing.

The Decision Matrix
Here’s the simple version:
- Fire box solid, 1–2 failed parts: Repair. Always. $35–$100 in parts.
- Fire box solid, all parts need replacing: Repair with aftermarket parts ($145–$200). Skip OEM if the grill is 8+ years old — aftermarket will outlast the fire box anyway.
- Fire box rusting, lid doesn’t seal, parts unavailable: Replace. And don’t buy another disposable grill this time.
- Propane regulator or hose failing: $20–$30 fix. Not a reason to replace anything. Replacement regulators on Amazon →
What to Buy If You’re Replacing
If your grill is genuinely done, here’s what the BIFL community on Reddit actually recommends — not what some sponsored list tells you to buy:
Weber Spirit E-310 (~$499): The consensus best gas grill under $500. Wirecutter’s top pick for years. Parts are available everywhere, including direct from Weber, Home Depot, and Amazon. The burner tubes, flavorizer bars, and grates are all user-replaceable. Expect 10–15 years with a parts refresh around year 7–8.
Weber Genesis E-325 (~$899): Step up if you want more cooking space (three burners plus a sear zone) and slightly better materials. Same parts availability advantage. Serious Eats’ top pick. Should last 15+ years with one mid-life refresh.
Napoleon Rogue 425 (~$549): The main Weber alternative. Owners on r/BuyItForLife report 10+ years. The advantage: Napoleon uses heavier stainless on some components. The disadvantage: parts are less widely available than Weber’s. If you’re the type who buys parts online, not a dealbreaker.
The common thread: buy a grill where every wear part is replaceable and parts are still stocked 10+ years later. That’s the actual BIFL test — not the metal thickness or the brand name, but whether you can still get parts for it in a decade.
Aftermarket vs OEM Parts: What’s Worth Paying For
Aftermarket grill parts have gotten significantly better in the last five years. Companies like SHINESTAR, HOMZEN, and GrillAce make stainless steel burner tubes and flavorizer bars that are sometimes thicker than the OEM Weber parts. I’m not making that up — measure them yourself.
Here’s my take on what to buy:
- Burner tubes: Aftermarket stainless is fine. The OEM Weber tubes are good, but $95 vs $40 for functionally identical stainless tubes is hard to justify on a 7-year-old grill.
- Flavorizer bars: Aftermarket is fine. Look for 18-gauge or thicker stainless. Thin ones will warp.
- Cooking grates: This is where I’d spend money. Cheap porcelain grates will chip and rust within 2–3 years. Stainless steel rod grates (either OEM or quality aftermarket) last 8–10+ years. Stainless grate options on Amazon →
- Igniters: Aftermarket electronic ignition kits are $12–$20 and work perfectly. The OEM Weber ones fail just as fast.
Cost-Per-Year: The Only Number That Matters
Let’s add up the full lifecycle costs for a 15-year ownership period — the real BIFL comparison:
Option A: Disposable Grill Cycle
Buy a $200 big-box grill every 5 years × 3 = $600 over 15 years = $40/year
No repairs possible. Just throw it out and start over.
Option B: Weber Spirit + One Full Refresh
$499 new + $145 aftermarket refresh at year 7 = $644 over 15 years = $43/year
Your grill works better at year 12 than the disposable one did at year 2.
Option C: Weber Genesis + One Full Refresh
$899 new + $200 aftermarket refresh at year 8 = $1,099 over 15 years = $73/year
More cooking space, better heat distribution, holds resale value if you ever sell it.
The Weber Spirit route costs almost the same per year as buying cheap grills and throwing them out. The difference is you’re not filling landfills with sheet metal every five years, and your food tastes better because the grill actually holds consistent heat.
This is the core BIFL argument, and it applies to more than just grills. We’ve made the same case for cast iron skillets that outlast five sets of nonstick pans and tools from brands that still stock parts for 30-year-old products. Pay once, maintain, keep it forever. The brands that have abandoned this model are the ones worth avoiding.
Maintenance That Actually Extends Grill Life
Most grill failures are preventable. The r/BuyItForLife thread on gas grills from late 2024 had a comment that stuck with me: a Weber owner whose grill is “close to 15 years old, kept outside the entire time, covered most of the time but rained on probably 100 times.” They replaced tubes, starter, grates, and drip covers at year 10. Still going.
Here’s what actually works:
- Clean the grates after every use. Not once a season. Every time. A wire brush or grill stone takes 60 seconds while the grill is still warm.
- Brush or blow out the burner tubes once a year. Spiders love propane grills. A clogged tube gives you uneven heat and eventually rusts from trapped moisture.
- Use a cover. Any cover. A $15 vinyl cover from Amazon is better than nothing. Grill covers on Amazon →
- Clean the grease tray. Grease fires destroy more grills than anything else. Pull the drip tray and wipe it out every few cooks.
- Don’t store it with the propane on. Tiny leaks over a winter will destroy the regulator and can corrode the valve assembly.
The Verdict
If your gas grill is 5–10 years old and the fire box is intact, repair it. A full aftermarket parts refresh costs $145–$200 and buys you another 5–8 years. That’s $18–$40 per year — cheaper than any new grill on the market.
If the fire box is rusting, the lid is warped, or parts simply don’t exist for your model anymore, replace it with something repairable. The Weber Spirit E-310 at ~$499 is the best balance of price, parts availability, and build quality. The Napoleon Rogue 425 is a solid alternative if you prefer their burner design.
And if you’re currently shopping the $200 aisle at the big-box store: don’t. You’ll be back in the same position in four years, reading another article just like this one.
