OEM Carrier Flame Sensor (48GS400192) for Model PY1PPB048130ABAA

This OEM Carrier flame sensor (part #48GS400192) is the factory-specified replacement for the Carrier PY1PPB048130ABAA gas furnace. The flame sensor — also called a flame rod — monitors burner ignition by detecting a small microamp electrical signal produced when the burner flame contacts the sensor tip. If the control board does not receive this signal within a few seconds of ignition, it cuts gas flow as a safety measure. The classic symptom of a failed or fouled flame sensor is a furnace that lights, runs for 5–8 seconds, then shuts off and locks out — cycling repeatedly without sustaining heat.

• Part Specs: 90° bend configuration | Includes mounting bracket | Approx. rod length 1.6" | Overall dimensions ~4.9" × 1.75" | Direct OEM replacement for Carrier part #48GS400192
• OEM vs Generic: This is a genuine Carrier OEM part matched to the exact rod geometry, alloy composition, and bracket angle of the factory original. Aftermarket sensors can vary in rod length and bend angle, leading to inconsistent flame signal readings and nuisance lockouts.
• Install Difficulty: 2/5 — Straightforward single-screw swap. Turn off gas and power before beginning. Tools needed: 1/4" hex driver, fine-grit emery cloth (to clean rod if reusing), multimeter (to verify microamp signal post-install). Tip: clean the burner port area before installing.
• Warranty: 1-year OEM manufacturer warranty against defects. In-stock and ships same business day from our warehouse.
