OEM Carrier Flame Sensor 48GS400192 for Model PY3PPA030060AA

This is the genuine OEM flame sensor (part number 48GS400192), factory-specified for the Carrier PY3PPA030060AA packaged unit. The flame sensor is a safety-critical component — it's a small metal rod that generates a microamp DC signal when immersed in the burner flame, confirming to the control board that ignition has been successful. When the sensor fails or becomes coated with oxidation, it can no longer pass sufficient current, causing the control board to cut gas flow as a precaution. The telltale symptom is a furnace or packaged unit that lights, runs for 5–8 seconds, then shuts down — repeating this lockout cycle until a fault code is triggered.

• Specs: OEM part number 48GS400192 | Factory-matched geometry and rod length | Correct bracket and connector configuration for PY3PPA030060AA | Microamp-rated sensing element
• OEM vs Generic: OEM sensors use the exact alloy and coating specified by Carrier engineering, ensuring reliable microamp signal output. Generic sensors may measure within tolerance when new but degrade faster, causing nuisance lockouts and unnecessary service calls.
• Install Difficulty: 2/5 — Turn off gas and 24V power before servicing. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers, and a multimeter capable of reading microamps (µA) to verify post-install signal (typically 1.5–4 µA DC). Clean the burner flame rod port of any soot before reinstalling.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
