The flame sensor — also called a flame rod — uses ionization\/rectification to verify that a burner flame is present after ignition. When the sensor detects a valid flame, it sends a small DC microamp signal to the control board to keep the gas valve open. A failed or heavily oxidized sensor cannot produce that signal, causing the board to close the valve as a safety measure. The telltale symptom: your furnace lights, runs for 5–8 seconds, then shuts off and locks out — often repeating 2–3 times before displaying a fault code.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 48GS400192 | 90-degree mounting bracket | Approximate rod dimensions: 1.6″ L × 4.9″ H × 1.75″ W | Factory-matched signal tolerance for the PY3PNA048130AB control board\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part — not an aftermarket imitation.
