OEM Carrier Flame Sensor (48GS400192) for Model PY3PEA060130AB

This OEM Carrier flame sensor is the factory-specified replacement part for the Carrier PY3PEA060130AB gas furnace. The flame sensor — also called a flame rod — is a critical safety component that detects the presence of a burner flame using electrical rectification. When the furnace fires, the sensor generates a small microamp current through the flame to confirm ignition. If the signal falls below threshold — typically due to a coated, corroded, or failed sensor rod — the integrated furnace control board will cut gas flow as a safety lockout. The result: your furnace lights briefly, then shuts off 5 to 8 seconds later, often repeating in failed ignition cycles.

• Part Specs: OEM Part # 48GS400192 | 90-degree rod angle with bracket mount | Approximate dimensions: 4.9" L × 1.75" H | Factory-matched microamp output
• OEM vs Generic: This is the genuine Carrier OEM sensor, built to exact factory tolerances for rod geometry, insulator material, and connector fit. Aftermarket sensors may not deliver a consistent microamp signal, risking nuisance lockouts or delayed fault detection.
• Install Difficulty: 2/5 — Shut off gas and power before servicing. Locate the flame sensor on the burner assembly near the heat exchanger. Disconnect the single wire lead, remove the mounting screw, and swap the rod. Lightly clean the new rod with fine steel wool before installing if needed. Tools: flat-head screwdriver, 1/4" nut driver, multimeter (to verify microamp reading of 2–6 µA).
• Warranty & Shipping: Backed by a 1-year OEM manufacturer warranty against defects. In stock — ships same business day from our warehouse.
