OEM Carrier 90° Flame Sensor (48GS400192) for Model PY3PNA060115NB

This is the genuine OEM Carrier flame sensor, part number 48GS400192, factory-specified for the Carrier PY3PNA060115NB gas furnace. The flame sensor — also called a flame rod — is a critical safety component that uses ionization/rectification technology to detect the presence of a burner flame during each heating cycle. When the burner ignites, the flame generates a small microamp DC signal through the rod; the control board reads this signal to confirm combustion. If the signal is absent or falls below threshold — commonly due to oxidation or carbon buildup on the rod tip — the board cuts gas flow within 5–8 seconds as a safety lockout. The result: your furnace starts, runs briefly, then shuts down and recycles repeatedly without heating the home.

• Part Number & Specs: OEM Part #48GS400192 | 90-degree rod orientation with mounting bracket | Dimensions approx. 4.9″ L × 1.75″ H | Designed for Carrier/Bryant gas furnace applications
• OEM vs. Generic: This factory-original sensor is precision-manufactured to exact microamp sensitivity specifications. Generic sensors may use substandard alloys that oxidize faster, leading to nuisance lockouts and premature failure — always choose OEM for a safety-critical component.
• Install Difficulty: 2/5 — Straightforward single-screw swap. Tools needed: 1/4″ nut driver or Phillips screwdriver, needle-nose pliers, fine steel wool or light sandpaper (to clean rod tip if reusing), and a multimeter to confirm microamp draw post-install. Always shut off gas and power before servicing.
• Warranty & Shipping: Backed by a 1-year OEM manufacturer warranty against defects. In stock and ships same business day from our warehouse.
