Gas burner wear shows up on caps, heads and spark electrodes long before the range itself is old. InterNACHI lists gas ranges at 15 to 17 years, but there's no published figure for the burner parts on their own. Spills, cleaning and how carefully the caps and heads go back on decide most of how they age.
Typical lifespan
Burner caps, heads and spark electrodes are simple parts, but they sit right where the heat, spills and cleaning happen. On a range that lasts 15 years or more, it's common for these parts to look worn well before the range does.
GE's guidance on slow or no ignition shows how often the cause isn't wear at all. Burner heads have to be in the correct position, caps have to match their heads and lie flat, and after cleaning or a spill, moisture in the burner's ignition port can keep a burner clicking until it dries.
What wears out first
| Part | Typical sign of wear |
|---|---|
| Burner caps | Chipped or worn enamel, warping, a cap that no longer sits flat |
| Burner heads | Clogged or enlarged flame ports, corrosion, uneven flame around the ring |
| Spark electrode | Cracked white porcelain, a weak or missing spark at one burner |
| Spark module | Clicking at all burners when only one is turned on, or clicking that won't stop |
| Burner valves and knobs | Knobs that slip, flames that won't hold a low setting |
| Grates | Chipped enamel, worn rubber feet, wobbling over the burner |
What shortens its life
- •Boil-overs and spills that run into the ports and the electrode.
- •Harsh scrubbing or abrasive tools that chip enamel on caps and grates.
- •Putting caps and heads back in the wrong place or crooked.
- •Putting burners back together while they're still wet. GE says to let them dry thoroughly after cleaning.
- •Knocking the electrode with pots or while cleaning.
What helps it last
- •Disconnect power before cleaning, as GE advises, then let parts dry thoroughly before putting them back.
- •Match each cap to its head and check that it sits flat.
- •Clear ports gently with a method your manual approves, not with a tool that can enlarge them.
- •Wipe up boil-overs once the burner is cool.
- •Check that the electrode sits flush; GE says to press it down with a twisting motion if it doesn't.
Signs of age vs. signs of a fixable fault
Worn burner parts show it over time: enamel chips on several caps, corrosion on the heads, flames that are uneven around the ring even when everything is clean and seated correctly.
Many burner problems aren't wear, though. A burner that clicks after cleaning is often still wet. A burner that lights on only part of its ring may have a cap out of place. GE notes that burners can need up to 10 or 12 clicks to light. A cracked electrode or a spark module that clicks constantly is a single failed part. If you smell gas, turn off the burners, leave the house and call 911 or your gas utility from outside. Gas valve work belongs with a technician. For the oven side, see gas oven igniter lifespan.

Takeaway: A burner that misbehaves right after cleaning is usually wet or misassembled, while true wear shows up as chipped caps and corroded heads across the cooktop.
