Weber Spirit 300 Parts

Bring your Weber Spirit 300 back to even, rust-free cooking.

You got a free or hand-me-down E-310, E-320, or E-330. The body’s fine, but the grates are flaking and the flames are uneven. Here are the exact, verified parts that fix it, and how to be sure they fit your grill before you order.

First: which grill do you actually have?

A hand-me-down Spirit is easy to mis-identify, and the wrong guess means a wrong-part return. Two minutes here saves that. Check these three things before you buy.

The 3 fitment traps (read before you buy)
  • Spirit 200 vs 300: count the burners. Two = 200-series (narrower), three = 300-series. These parts are for the 3-burner 300.
  • Front vs side controls: modern E-310/320/330 (2013+) have knobs on the FRONT panel. Older side-control models use different bars and igniters.
  • Spirit 310 vs Genesis 310: they’re different grills. A Genesis is larger, so check the badge on the lid or cart. The grates here also fit Genesis 300, but the burner set is Spirit-specific.

Save or replace?

Before you spend a dollar, here’s what to keep and what to swap on a typical hand-me-down Spirit 300.

Cooking gratesReplace if rusted, pitted, or flaking
Flavorizer barsReplace if rusted thin or warped
Burner tubesReplace if flames are uneven or ports are corroded
IgniterReplace if no spark (cheap fix)
Firebox, lid, cartSave (unless rusted through)
Knobs, wheels, handleSave (rarely an issue)

The restore, step by step

Five moves, in order. The picks you’ll need are grouped lower down, so the steps stay about the work.

Confirm it’s a front-control Spirit 300

Two minutes now saves a wrong-part return.

Deep dive

Count the burners: three means a 300-series, two means a 200. Then check the control panel. The parts here fit the modern front-control models, with knobs on the front, not the older side-control layout.

Finally, read the badge on the lid. It should say Spirit, not Genesis. A Genesis is a larger, different grill. Use the three fitment traps above as your checklist before you order.

Replace the cooking grates

The single biggest cooking upgrade on a tired grill.

Deep dive

Lift out the old grates. If they’re rusted, pitted, or flaking, they’re what your food touches and the most common thing to replace. The cast-iron set drops straight into the 3-burner E-310/320/330.

New cast iron rusts fast if you skip seasoning, so season it before the first cook (that’s step 4). The grates are in the parts group below.

Swap the Flavorizer bars and burner tubes

This is what fixes uneven heat and flare-ups.

Deep dive

The Flavorizer bars sit over the burners and take the grease hit, so they rust out first and cause flare-ups. The three burner tubes corrode at the ports, which is what makes the flame weak or uneven.

Replacing both restores a full, even flame across all three burners. Both parts are in the group below. Buy only what yours needs.

Re-season the new cast iron

Keeps the new grates from rusting again.

Deep dive

Wipe a thin coat of high-smoke-point oil onto the new grates, run the grill hot to burn it in, and repeat the wipe-and-burn once or twice. Skip olive oil: its smoke point is too low and it’ll just turn gummy.

The oil and towels you’ll want are in the last group below.

Check the igniter, then cook

A dead igniter is the cheapest annoyance to fix.

Deep dive

Click the igniter and listen for a spark. If it won’t fire, the igniter kit is a quick swap, but the exact kit varies by model and year, so match one to your front-control 300 (there’s a tag-attributed search for that in the FAQ below).

After any burner or igniter work, brush soapy water on the gas connections and watch for bubbles before you cook. Bubbles mean a leak; no bubbles, you’re good to light.

Two safety musts

Disconnect the propane before any burner or igniter work. And before you cook, brush soapy water on the gas connections and watch for bubbles. Bubbles mean a leak; no bubbles, you’re good to light.

The parts that wear out

The three things that actually fail on a hand-me-down Spirit 300. Buy only what yours needs.

Igniter dead too? The right kit depends on your exact model and year, so we point to a tag-attributed Amazon search for a front-control Spirit 300 igniter → rather than guess a single SKU. Match it to your grill before buying.

Season it & cook

Protect the new grates and get cooking, so you never have to rescue this grill twice.

FAQ

How do I know if I have a Spirit 300 and not a 200?

Count the burners. The Spirit 300 series (E-310/E-320/E-330) has three; the 200 series has two and is narrower. The parts here are for the three-burner 300.

Do these fit a front-control or side-control Spirit?

Front-control: the 2013-and-newer models with the knobs on the front panel. Older side-control Spirits use different Flavorizer bars and igniters.

Will the grates fit a Genesis 300 too?

Yes, the cast-iron grates fit both Spirit and Genesis 300. The burner tube set is Spirit-specific, so match that to your exact model.

Which part should I replace first?

The grates, if they're rusted or flaking. They're what your food touches and the biggest single upgrade. If the heat is uneven, do the Flavorizer bars and burner tubes.
