OEM Carrier Flame Sensor 48GS400192 for Model PY3PPA060115AA

This is the genuine OEM replacement flame sensor (part number 48GS400192) factory-specified for the Carrier PY3PPA060115AA packaged gas unit. The flame sensor — also called a flame rod — is a safety-critical component that detects the presence of a burner flame and sends a microamp signal to the control board to confirm ignition. When the sensor is coated with oxidation or fails entirely, the control board cannot verify a flame is present, causing the furnace to light briefly and then shut down in a safety lockout, typically within 5 to 8 seconds of ignition. The result is a no-heat condition with repeated ignition retry cycles and a fault code on the control board.

• Specs: OEM part number 48GS400192 | Factory-matched rod length and bracket angle | Stainless steel sensing rod | 1/4" female quick-connect terminal
• OEM vs Generic: This OEM sensor is manufactured to Carrier's exact microamp output and rod geometry specifications. Generic flame sensors often feature incorrect rod lengths or substandard stainless alloys that oxidize faster, leading to repeat no-heat calls within one heating season.
• Install difficulty: 2/5 — Shut off gas and power before servicing. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers, multimeter (to verify microamp signal, typically 1–4 µA). Always inspect the igniter and burners while the unit is open.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.
