OEM Carrier Flame Sensor w/ Wire LH680014 for Model PG8MAA066135ABJA

This is the OEM factory-specified flame sensor with attached wire harness for the Carrier PG8MAA066135ABJA gas furnace. The flame sensor is a critical safety component — it detects the presence of a burner flame by passing a small microamp current through the flame to ground. When the sensor rod becomes oxidized or coated with residue, the control board can no longer confirm ignition and will shut down the gas valve within 5–8 seconds, causing the furnace to short-cycle or lock out on repeated ignition failures. Replacing the flame sensor is one of the most common and cost-effective furnace repairs.

• OEM Part Number: LH680014 | Includes pre-attached wire lead | 45° rod mounting angle | High-temperature Kanthal flame rod material | Alumina ceramic insulator
• OEM vs Generic: This OEM Carrier part is manufactured to exact factory microamp detection tolerances. Aftermarket sensors can exhibit drift in flame signal readings, causing nuisance lockouts or, worse, delayed shutoff — making OEM the only safe choice for this safety-critical component.
• Install Difficulty: 2/5 — Straightforward single-screw mounting. Turn off power and gas before beginning. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers. Disconnect the old wire lead, remove the mounting screw, swap the sensor, and reconnect. Verify microamp signal (≥1.0 µA) with a multimeter in series after installation.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
