OEM Carrier Flame Sensor 48GS400192 for Model PY2PPB060115AA

This is the factory OEM flame sensor (part number 48GS400192) designed as a direct replacement for the Carrier PY2PPB060115AA packaged gas/electric unit. The flame sensor is a critical safety component — a thin metallic rod that uses electrical current to verify a burner flame is present. When the sensor detects flame, it signals the control board to keep the gas valve open. When the sensor fails or becomes coated with oxidation, the board cannot confirm combustion and shuts the system down within 5–8 seconds of ignition as a safety precaution, resulting in a no-heat lockout condition.

• Specs: OEM part number 48GS400192 | Factory-matched flame rod geometry and connector | Designed to exact microamp current specifications for Carrier control boards | Direct plug-in replacement — no modification required
• OEM vs Generic: This is the genuine Carrier OEM sensor, not an aftermarket substitute. OEM sensors are manufactured to precise microamp sensing thresholds that match the control board's fault tolerance window — generic sensors often fall outside this window, causing nuisance lockouts or premature failure.
• Install Difficulty: 2/5 — Always shut off gas supply and 120V power before servicing. Tools needed: 1/4" hex driver, needle-nose pliers, multimeter (to verify microamp draw post-install). Gently clean the rod with fine steel wool if reusing; replace if cracked or heavily corroded. Photograph existing wiring harness before disconnecting.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
