OEM Carrier Flame Sensor with Wire (LH680014) for Model PG8JAA066110ACJA

This OEM flame sensor with wire is the factory-specified replacement part for the Carrier PG8JAA066110ACJA gas furnace. The flame sensor is a critical safety component — a metal rod mounted in the burner assembly that detects whether a flame is actually present after the igniter fires. When it fails or becomes coated with oxidation, the furnace control board can't confirm ignition and will shut down the gas valve as a safety precaution. The tell-tale symptom: your furnace lights for 5–8 seconds and then shuts off, typically cycling through 3 lockout attempts before going into hard lockout.

• Part Number: LH680014 | Includes attached wire lead | 45-degree rod angle | Compatible with Carrier LH33ZS004 igniter | Replaces: LH680012, LH33WZ517, LH33WZ511, LH33WZ515, LH33WZ521
• OEM vs Generic: This OEM part is built to Carrier's exact metallurgical specifications using high-temperature Kanthal flame rod material, ensuring accurate microamp signal output. Generic sensors can produce erratic readings that cause nuisance lockouts or fail prematurely under continuous heat cycling.
• Install Difficulty: 2/5 — Shut off gas and power before beginning. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers. Disconnect the wire lead, remove the single mounting screw, swap the sensor, and reconnect. Verify proper flame signal (1.5–4 microamps DC typical) with a multimeter after installation.
• Warranty: 1-year OEM factory warranty against defects. In stock and ships same business day from our warehouse.
