OEM Carrier Flame Sensor 48GS400192 for Model PY3PPA060115AB

This OEM Carrier flame sensor (part #48GS400192) is the factory-specified replacement for the Carrier PY3PPA060115AB gas furnace. The flame sensor is a critical safety component — its rod is positioned directly in the burner flame, where it generates a small DC microamp signal via flame rectification to confirm combustion is present. When the sensor fails or becomes coated with oxidation, the furnace control board cannot verify ignition and will shut the gas valve off within 5–8 seconds of startup, causing repeated lockout cycles and a no-heat condition.

• Specs: 90° angled flame rod | Integrated mounting bracket | OEM-matched microamp output | Approximate rod length 1.6" | Overall dimensions approx. 4.9" × 1.75" | Compatible with natural gas and propane burner configurations
• OEM vs Generic: This is a genuine Carrier OEM part with factory-calibrated rod geometry and insulator composition. Generic sensors may deviate in rod angle or porcelain insulator quality, leading to intermittent signal drop-out and nuisance lockouts — especially in colder ambient conditions.
• Install difficulty: 2/5 — Turn off power and gas before servicing. Tools needed: 1/4" hex driver or nut driver, fine steel wool or emery cloth (to clean rod if reusing), multimeter (to verify microamp draw of 1.5–4 µA DC). Disconnect the single wire connector, remove the one mounting screw, swap sensor, and reconnect. Average install time: 10–15 minutes.
• Warranty: 1-year OEM manufacturer warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as the direct OEM replacement for Carrier model PY3PPA060115AB packaged gas/electric units.
