The flame sensor is a small but critical safety component — a metal rod that detects whether a flame is actually present after the gas valve opens. It passes a small electrical current through the burner flame; if no flame is sensed within seconds, the control board shuts down the gas valve to prevent unburned gas from accumulating. When the sensor fails or becomes coated with oxidation, the furnace will light briefly and then shut off after just 5 to 8 seconds, often repeating the ignition cycle two or three times before locking out entirely.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number LH33WZ009A | Factory-matched flame rod material and geometry | 1\/4\" male quick-connect terminal | Designed for Carrier single-stage gas furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM flame sensors use the exact rod alloy and mounting geometry specified by Carrier engineering. Generic alternatives may produce a weaker microamp signal, causing nuisance lockouts even after cleaning — particularly in low-ambient or humid conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Turn off gas and power before beginning. Tools needed: 1\/4\" or 5\/16\" nut driver, fine steel wool or emery cloth (to clean rod if reusing), multimeter (to verify microamp draw post-install). Disconnect the single wire connector, remove the mounting screw, swap the sensor, and reconnect. Total job typically under 15 minutes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1-year OEM factory warranty.
