The flame sensor — also called a flame rod — is a critical safety component that uses ionization\/rectification technology to verify a live burner flame during each heating cycle. When it detects the flame's electrical signal, it tells the control board to keep the gas valve open. A failed or carbon-coated sensor can no longer pass sufficient microamp current, causing the furnace to light briefly and then shut down within 5–8 seconds, triggering a lockout fault code. Replacing this part restores normal heating operation immediately.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 48GS400192 | 90-degree mounting angle | Includes mounting bracket | Factory-matched for Carrier PY2PNB036090AA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier OEM part manufactured to exact factory tolerances. Aftermarket flame sensors often use lower-grade rod alloys that coat with carbon faster, reducing service life and causing repeat nuisance shutdowns.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Turn off gas and power before servicing.
