The flame sensor is a critical safety component — a small but vital rod that uses ionization\/rectification to confirm a live burner flame during each heating cycle. When it detects a flame, it allows the gas valve to stay open. When it fails or becomes coated with oxidation, the furnace will light briefly, then shut down within 5–8 seconds as the control board interprets no flame signal and initiates a safety lockout. Repeated short-cycling, error codes, or a furnace that never reaches setpoint temperature are all telltale signs of a failed or fouled flame sensor.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Specs:\u003c\/strong\u003e 90° angled flame rod with integrated mounting bracket | OEM part number 48GS400192 | Approx. dimensions: 4.9\"(H) × 1.75\"(W) × 1.6\"(L) rod | Direct factory-matched fit for Carrier PY2PPB030040AB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part built to exact factory metallurgy and geometry specifications.
