OEM Carrier Flame Sensor 48GS400192 for Model PY1PPB036090AAAA

This is the factory OEM replacement flame sensor (part number 48GS400192) for the Carrier PY1PPB036090AAAA gas furnace. The flame sensor — also called a flame rod — is a safety component that detects the presence of a burner flame by passing a small electrical current through the flame itself. When the control board cannot confirm flame presence, it shuts off the gas valve within 5–8 seconds as a safety measure. A dirty or failed flame sensor is one of the most common causes of a furnace that lights briefly and then locks out repeatedly.

• Specs: OEM part number 48GS400192 | Single-rod flame detection design | Factory-matched mounting bracket and rod geometry | Compatible with Carrier 24V control board systems
• OEM vs Generic: This is a genuine OEM Carrier flame sensor, manufactured to exact factory specifications. Generic aftermarket sensors may have incorrect rod length, poor coating quality, or incompatible bracket geometry — all of which can cause nuisance lockouts or premature failure.
• Install Difficulty: 2/5 — Turn off gas and 120V power before servicing. Tools needed: 1/4" hex or Torx driver (varies by bracket), needle-nose pliers. Lightly sand the rod with fine steel wool if replacing for contamination only — if cracked or broken, replace fully. Always clear fault codes after installation.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
