OEM Carrier Flame Sensor 48GS400192 for Model PY2PNB060130AB

This OEM flame sensor (part number 48GS400192) is the factory-specified replacement for the Carrier PY2PNB060130AB gas furnace. The flame sensor — also called a flame rod — is a critical safety component that detects the presence of a burner flame and signals the control board to keep the gas valve open. When the sensor becomes coated with oxidation or mineral buildup, its electrical signal weakens, and the control board interprets this as a "no flame" condition. The result: your furnace lights, runs for 5–8 seconds, then shuts off and locks out — often repeating the cycle 3 times before going into full lockout.

• Specs: OEM Carrier flame sensor | Part No. 48GS400192 | Single-rod design | Factory-matched resistance and rod geometry for precise flame current detection
• OEM vs Generic: OEM flame sensors are manufactured to exact rod length, insulator material, and bracket geometry tolerances. Generic sensors can produce inconsistent microamp readings, causing nuisance shutdowns even when clean — always choose OEM for reliable ignition.
• Install Difficulty: 2/5 — Turn off gas and power before servicing. Tools needed: 1/4" or 5/16" nut driver, fine steel wool or light sandpaper (to clean rod if reusing), multimeter with microamp setting to verify ~2–4 µA flame current after installation.
• Warranty: 1-year OEM factory warranty. In stock — ships same business day from our warehouse.

Compatibility: Designed for the Carrier PY2PNB060130AB gas furnace. Always verify your existing part number on the sensor bracket or in your unit's wiring diagram before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork required.
