It is the direct, drop-in fit for the \u003cstrong\u003eCarrier PG95SAS30040AAAA\u003c\/strong\u003e 95% AFUE gas furnace. The flame sensor is a safety-critical component: a small metal rod positioned in the burner flame that passes a micro-amp current through the flame to confirm ignition. When the sensor fails or becomes coated with oxidation, the furnace control board cannot verify flame presence and will shut off the gas valve — typically after 5 to 8 seconds of operation — triggering a lockout fault and leaving you without heat.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e LH680534 (current) | LH33WZ521 (superseded\/discontinued) — this listing ships the current LH680534 revision, which includes a pre-attached lead wire for easy plug-in installation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e Genuine Carrier OEM sensors are manufactured to exact rod geometry, insulation thickness, and micro-amp response specifications.
