The flame sensor is a critical safety component — a small metal rod that detects the presence of a burner flame by passing a small electrical current through it. When the control board cannot confirm flame, it shuts off the gas valve within 5 to 8 seconds as a safety precaution. A dirty, cracked, or failed flame sensor is one of the most common causes of furnace short-cycling: the burner lights, runs briefly, then shuts down — often repeating in lockout after 3 attempts.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number LH33WZ009A | Factory-matched rod length and bend angle | 1\/4\" female quick-connect terminal | Stainless steel sensing rod with ceramic insulator\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM sensors are precision-matched to the control board's microamp threshold for the LC350HE400812. Generic sensors often fall outside acceptable microamp range, causing nuisance shutdowns even after installation — choose OEM for a confirmed fix.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 2\/5\u003c\/strong\u003e — Turn off power and gas before servicing. Tools needed: 1\/4\" hex driver or nut driver, needle-nose pliers. Disconnect the wire harness, remove the single mounting screw, and swap the sensor. Lightly sand the rod only if reusing; always replace if cracked or heavily oxidized.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
