This OEM Carrier flame sensor is the genuine flame-rectification probe for the G1RS050A12 gas furnace. After the igniter lights the burners, the sensor confirms the presence of a flame and signals the control board to hold the gas valve open. Over time oxide buildup or a hairline crack prevents the sensor from reading flame, causing the furnace to ignite and then shut down within seconds and lock out, the classic short-cycling no-heat symptom. This sensor is built to the exact rod length and mounting geometry of the G1RS050A12 for a true direct-fit installation with no bending required. The job is easy for most homeowners and HVAC techs: cut power, remove the single screw, unplug the spade terminal, and install the replacement. A clean OEM sensor restores dependable flame proving and steady heat. We keep genuine Carrier parts in stock and ship same-day on orders placed before 3PM CST, so the furnace is running again fast. Replace with the igniter for a complete ignition-system refresh and improved reliability.
This part is compatible with Carrier model G1RS050A12.
