OEM Carrier Flame Sensor (48GS400192) for Model PY2PNB030060AB

This OEM Carrier flame sensor is the factory-authorized replacement part for the Carrier PY2PNB030060AB gas furnace. The flame sensor — also called a flame rod — is a critical safety component mounted in the burner assembly. It detects the presence of a burner flame via electrical rectification: when a live flame contacts the rod, a small microamp DC signal is passed back to the control board confirming ignition. If the board never receives that signal — due to a failed, oxidized, or carbon-coated sensor — it will cut the gas valve within 5 to 8 seconds as a safety lockout. The result is a furnace that appears to ignite momentarily, then shuts off repeatedly without ever heating your home.

• Part Specs: OEM Part # 48GS400192 | 90-degree mounting angle | Approx. rod length 1.6 in. | Overall dimensions approx. 4.9 in. × 1.75 in. | Factory-matched microamp signal tolerance
• OEM vs. Generic: This is a genuine Carrier OEM part, manufactured to exact factory specifications. Generic flame sensors vary in rod alloy and connector fit, which can cause intermittent signal dropouts and repeat lockouts even after installation. OEM is the reliable fix the first time.
• Install Difficulty: 2/5 — Turn off power and gas before starting. Tools needed: 1/4 in. hex driver or nut driver, fine-grit emery cloth (to clean rod if reusing), and a multimeter to verify microamp draw. Photograph wire connector orientation before removal. The sensor mounts with a single screw to the burner bracket.
• Warranty: Backed by a 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse — order by 3 PM local time for same-day dispatch.
