The flame sensor — also called a flame rod — is a critical safety component that uses ionization\/rectification technology to detect the presence of a burner flame during each heating cycle. When the control board initiates ignition, the sensor generates a small DC microamp signal confirming combustion. If that signal is absent or too weak (typically due to carbon buildup or a failed rod), the board shuts off the gas valve within 5–8 seconds as a safety measure, causing a no-heat lockout condition. Replacing this part with the correct OEM unit restores proper flame detection and eliminates nuisance lockouts.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 48GS400192 | 90-degree flame sensor with mounting bracket | Carrier OEM factory specification\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e OEM sensors are calibrated to the exact microamp threshold required by the Carrier control board on the PY1PPB048115NBAA.
