OEM Carrier Flame Sensor 48GS400192 for Model PY1PPB030060AAAA

This OEM flame sensor (part number 48GS400192) is the factory-specified replacement for the Carrier PY1PPB030060AAAA furnace. The flame sensor is a small but critical safety component — it generates a microamp signal that proves a live flame is present after the gas valve opens. When the sensor rod becomes coated with oxidation or carbon buildup, it can no longer pass enough current to satisfy the control board, causing the furnace to ignite briefly and then shut down within 5 to 8 seconds. Left unaddressed, this fault will trigger a lockout code and leave you with no heat.

• Specs: OEM part number 48GS400192 | Single-rod flame sensing design | Factory-matched microamp output | Fits Carrier PY1PPB030060AAAA packaged gas system
• OEM vs Generic: OEM flame sensors are manufactured to exact rod geometry and alloy specifications, ensuring consistent microamp output within the control board's acceptance window. Generic sensors can fall outside that range, causing nuisance lockouts even when clean.
• Install difficulty: 2/5 — Turn off gas and 120V power before starting. Tools needed: 1/4" hex driver or flat-head screwdriver, fine steel wool or emery cloth (for rod cleaning at inspection), and a multimeter capable of reading microamps to verify operation. Disconnect the single wire connector, remove the one mounting screw, swap the sensor, and reconnect.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.
