Types of sear burners
Most sear burners on built-in grills are infrared: a ceramic tile or metal mesh panel that glows red-hot. Some brands use a high-output tube burner with a heavier grate instead. A few grills offer a sear zone that can be swapped in for a standard burner. They all run hotter and dirtier than the rest of the grill, and they fail in a few predictable ways.
If yours is the ceramic infrared type, much of what's on our infrared burner page applies here too.
What goes wrong, most common first
Grease-clogged surface
Steak fat drips straight onto the sear burner and carbonizes. Clogged areas go dark and the burner stops getting fully hot.
Won't light
The igniter electrode on a sear burner sits close to intense heat and fails sooner. Spiders in the inlet are also common because these burners sit idle.

Water, dropped grates and thermal shock crack ceramic. Metal mesh burns through over time.
Lights then goes out
Many sear burners have a thermocouple safety valve. If the sensor is dirty or failing, it won't hold the gas on.

The heavy grate over the sear burner can warp from heat and sit unevenly, giving poor contact and patchy marks.
Learn moreThings you can check
- After searing, leave the sear burner on high with the hood open for a few minutes to burn off drips.
- With the grill off and cold, lift the sear grate and look at the burner face for dark patches, cracks, or holes in mesh.
- Press the igniter and watch for a spark at the sear burner's electrode.
- If it has a push-and-hold knob, hold it in for the time your manual specifies before letting go.
- Never spray water on a hot sear burner or use it as a place to put out flare-ups.
How we fix sear burners
- 1
Diagnose
We check ignition, gas flow, glow pattern and the safety valve. Each points to a different fix.
- 2
Clean the zone
The sear burner area, grate, and surrounding firebox get degreased. Much of the grease that kills sear burners collects below and around them.
- 3
Clear the inlet
Venturi and orifice checked and cleared of webs and debris.
- 4
Replace parts as needed
Igniter, thermocouple, or the full burner assembly when the tile is cracked or the mesh is burned through.
- 5
Test at full heat
We light the sear burner, let it come up, and confirm an even glow and stable flame.
Brand-specific parts
Sear burners are rarely interchangeable. A Lynx Trident, a Viking TruSear, an Alfresco sear zone and a Blaze infrared burner are all different. We work from the model tag, and our model and serial number guide shows where to find it. On older grills where the original is no longer made, we'll tell you honestly whether a repair is possible.
A sear burner that's regularly cleaned lasts much longer. If yours gets heavy use, a maintenance plan keeps it from becoming a recurring repair.
Sear burner questions
Can I convert my sear burner back to a regular burner?
On some grills, yes. Certain brands make sear and standard burners that fit the same position. On many built-ins the sear zone is fixed. We can check yours.
Why does my sear burner smoke so much?
Grease and fat burning off the surface. Some smoke is normal when searing. Heavy smoke at startup means built-up grease that should be cleaned.
Is a dark patch on the sear burner a problem?
It means that section isn't burning properly, usually from clogging. Burning it off on high sometimes clears it. If it doesn't, the burner may need service or replacement.
Should I cover the sear burner when not in use?
Keeping the hood closed and the grill covered helps keep water and debris off it. Just make sure the burner is completely cool first.
How much does sear burner repair cost?
It depends on the brand and whether it's a part replacement or a full burner. Send photos and the model number and we'll quote it.
