The flame sensor (also called a flame rod) is a critical safety component mounted in the burner assembly — it detects the presence of a live flame by passing a small microamp current through the flame to ground. When the sensor's rod becomes coated with oxidation or the component fails entirely, the furnace control board can no longer confirm ignition. The result: the furnace lights briefly, then shuts off after 5–8 seconds and enters a safety lockout, typically flashing a fault code indicating \"flame sense failure.\" Replacing the flame sensor is one of the most common and cost-effective furnace repairs available.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e Primary — \u003cstrong\u003eLH33WZ521\u003c\/strong\u003e (Flame Sensor) | Alternate — \u003cstrong\u003eLH680534\u003c\/strong\u003e (Flame Sensor w\/Lead).

Aftermarket sensors often use lower-grade rods that re-oxidize faster, leading to repeat service calls within a single heating season.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Turn off power and gas before beginning. Tools needed: 1\/4\" hex driver or nut driver, needle-nose pliers, and optionally a multimeter (to verify microamp draw of 1–4 µA). The sensor mounts with a single screw on the burner bracket. Always clean the burner area and inspect the igniter while the furnace is open.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty \u0026amp; Shipping:\u003c\/strong\u003e Backed by a 1-year OEM factory warranty.
