OEM Carrier 90° Flame Sensor (48GS400192) for Model PY2PNB036060AA

This OEM flame sensor is the factory-specified replacement for the Carrier PY2PNB036060AA gas furnace. The flame sensor — also called a flame rod — is a critical safety component that uses ionization/rectification to detect the presence of a burner flame during each heating cycle. When the sensor becomes coated with oxidation or simply fails, the furnace control board cannot confirm ignition, triggering a safety lockout. The most telling symptom: the burner lights normally, then shuts off after just 5–8 seconds, often repeating two or three times before locking out entirely.

• Part Number & Specs: OEM Part #48GS400192 | 90-degree bend orientation | Includes mounting bracket | Approx. rod length 1.6" | Overall dimensions approx. 4.9" × 1.75" — factory-matched for direct drop-in fitment
• OEM vs Generic: This is a genuine Carrier OEM component manufactured to exact factory tolerances. Generic flame sensors often use inferior rod alloys that oxidize faster, leading to repeat nuisance lockouts within one heating season. OEM ensures proper microamp signal output and full compatibility with the PY2PNB036060AA control board.
• Install Difficulty: 2/5 — A straightforward repair for a confident DIYer. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers, fine steel wool or emery cloth (for light cleaning of rod before install). Always shut off furnace power and gas before servicing. Disconnect the single wire connector, remove the one mounting screw, swap the sensor, and reconnect.
• Warranty & Shipping: Backed by a 1-year OEM factory warranty against manufacturing defects. In stock and ships same business day from our warehouse.
