OEM Carrier Flame Sensor (48GS400192) for Model PY2PEB036060AA

This is the OEM factory-specified flame sensor for the Carrier PY2PEB036060AA gas furnace. The flame sensor — also called a flame rod — is a critical safety component that detects the presence of a live burner flame using electrical rectification. When the control board initiates ignition, this sensor confirms combustion is occurring; if it fails to send a valid signal (due to oxidation, carbon buildup, or a cracked rod), the board shuts off the gas valve within 5–8 seconds as a safety lockout. The result: your furnace lights briefly, then goes cold — typically repeating in 3-try lockout cycles.

• OEM Part Number: 48GS400192 | 90-degree rod orientation with integrated bracket mounting | Compact form factor: approx. 4.9" L × 1.75" H
• OEM vs Generic: This is a genuine Carrier OEM part, manufactured to exact factory specifications for rod alloy, insulator ceramic, and lead wire length. Generic sensors can have marginal rod coatings that degrade faster and trigger nuisance lockouts.
• Install Difficulty: 2/5 — Power down the furnace and wait for components to cool before servicing. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers, and a soft wire brush or fine steel wool to inspect the burner port. Disconnect the single wire connector, remove the mounting screw, swap the sensor, and reconnect. Always confirm flame signal with a microamp meter if available.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.
