OEM Carrier Flame Sensor with Lead LH680534 for Model PG96VAT66120DDAA

This is the factory OEM flame sensor with lead wire for the Carrier PG96VAT66120DDAA 96% AFUE two-stage gas furnace. The flame sensor is a critical safety component — its rod is submerged in the burner flame and generates a small microamp (µA) DC signal that tells the integrated furnace control (IFC) board that combustion is actually occurring. If the sensor is coated with oxidation or has failed, the board cannot confirm a flame and will shut off the gas valve within 5–8 seconds of ignition as a safety lockout. The furnace will typically attempt ignition 3 times before going into hard lockout, requiring a manual reset.

• Specs: OEM part number LH680534 | Includes pre-attached lead wire for direct plug-in replacement | Factory-matched µA output | Compatible with Carrier IFC board signal threshold
• OEM vs Generic: This OEM unit ships with the correct rod geometry, ceramic insulator rating, and lead wire gauge specified by Carrier engineering. Generic sensors may produce weaker µA signals, causing nuisance lockouts even with a clean flame.
• Install Difficulty: 1/5 — One of the easiest furnace repairs. Tools needed: 1/4" hex driver or nut driver, fine steel wool or emery cloth (for light oxidation cleaning). Always shut off gas and power at the disconnect before servicing. Plug in the lead wire connector and secure with a single screw.
