OEM Carrier Flame Sensor 48GS400192 for Model PY1PEB048130AAAA

This is the genuine OEM flame sensor (part #48GS400192) factory-specified for the Carrier PY1PEB048130AAAA furnace. The flame sensor — also called a flame rod — uses ionization current to verify that burner flame is present after ignition. When carbon buildup or corrosion degrades the rod, the furnace control board can no longer confirm a valid flame signal. The result: the gas valve closes as a safety precaution, and the furnace shuts off 5–8 seconds after lighting — often locking out after 3 failed attempts and displaying a fault code.

• Specs: Flame rod sensor | Approx. rod length 1.6 in. | Overall dimensions ~4.9 in. × 1.75 in. | Single-wire ionization circuit | Direct drop-in OEM replacement
• OEM vs Generic: This is a genuine Carrier OEM part manufactured to exact factory tolerances. Generic sensors can vary in rod geometry and connector fit, leading to nuisance lockouts and premature failure. OEM ensures proper ionization signal strength recognized by your Carrier control board.
• Install Difficulty: 2/5 — Turn off power and gas supply before servicing. Tools needed: 1/4" or 5/16" nut driver, flat-head screwdriver, fine steel wool or emery cloth (to clean rod if reusing). Disconnect the single wire harness, remove the mounting screw, swap sensors, and reconnect. Average DIY time: 15–20 minutes.
• Warranty: Backed by a 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
