The flame sensor — also called a flame rod — uses ionization\/rectification to detect whether a burner flame is actually present after ignition. When it detects a valid flame, it sends a microamp signal to the control board to keep the gas valve open. A failed or coated sensor sends a weak or absent signal, causing the furnace to light briefly and then shut off within 5–8 seconds, repeating in lockout cycles until the fault is resolved.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 48GS400192 | 90-degree mounting bracket | Compatible with Carrier gas furnaces including the PY3PPA042090NB series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part — factory-matched geometry, rod metallurgy, and bracket angle.
