The flame sensor is a safety-critical component that monitors the presence of a burner flame by passing a small electrical current through the rod and into the flame. If the control board does not detect the correct microamp (µA) signal within seconds of ignition, it will cut gas flow and lock out the system. A dirty, cracked, or corroded flame sensor is one of the most common causes of a furnace or packaged unit that lights, then shuts off after 5–8 seconds — often repeating in a frustrating cycle before going into full lockout.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 48GS400192 | Direct factory replacement — no modifications required for Carrier \u003cstrong\u003ePY3PNA036090NA\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM sensor is manufactured to exact factory microamp sensitivity tolerances. Aftermarket sensors often exhibit wider tolerance ranges, leading to nuisance lockouts or, worse, delayed flame-loss detection — making OEM the only safe choice for gas appliances.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Shut off gas supply and 120V power before servicing.
