The flame sensor is a critical safety component — it uses ionization\/rectification technology to detect the presence of a burner flame during each heating cycle. When the furnace ignites, the flame produces a small microamp electrical signal that the sensor sends back to the control board to confirm combustion. If the board doesn't receive that signal within a few seconds, it cuts off the gas valve as a safety measure. A failed or carbon-fouled sensor is one of the most common reasons a furnace will fire up, then shut off after just 5–8 seconds, leading to a no-heat lockout condition.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 90° mounting angle | Approx. 4.9\" L × 1.75\" H | Includes mounting bracket | Factory OEM fit for Carrier\/Bryant gas furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier-manufactured sensor rod, ensuring correct microamp sensitivity and exact dimensional fit.
