The genuine Goodman 0130F00010S flame sensor is a direct-fit replacement for the GMH950905CXAB 96% AFUE two-stage gas furnace. The flame sensor is a small but critical safety component: it uses flame rectification to confirm that the burners have actually lit after ignition. A dirty, cracked, or worn sensor is the single most common cause of a furnace that lights briefly and then shuts down on a lockout, so replacing it restores dependable heat during the coldest months.
This is a genuine Goodman OEM sensor, machined to the exact rod length and mounting geometry of the original. Generic universal sensors often require bending or adapter brackets and can produce inconsistent microamp readings that trip intermittent lockouts. The OEM part drops in with no guesswork.
Easy (1/5). Typically a single screw and one spade connector. Always cut power at the disconnect before servicing. If you are unsure, a licensed HVAC technician can install it in minutes.
