OEM Carrier Flame Sensor with Wire — Part #LH680014 for Model PG8DAA024070ACJA

This is the OEM factory-specified flame sensor with wire harness for the Carrier PG8DAA024070ACJA gas furnace. The flame sensor is a critical safety component in the hot surface ignition (HSI) system — it detects the presence of a burner flame and sends a microamp signal to the control board to confirm combustion. When the sensor becomes coated with oxidation or fails entirely, the furnace will ignite briefly and then shut down after 5–8 seconds in a safety lockout, leaving your home without heat.

• Specs: 45° angled flame rod | Kanthal high-temperature rod material rated to 1,800°F | Alumina ceramic insulator | Includes OEM wire harness lead | Replaces LH33WZ511, LH33WZ515, LH33WZ517, LH680012
• OEM vs Generic: This OEM Carrier part (LH680014) is factory-matched to the PG8DAA024070ACJA control board's microamp sensing range. Generic sensors can read outside the board's acceptance threshold, triggering false lockouts or nuisance shutdowns even when the flame is healthy.
• Install Difficulty: 2/5 — Turn off gas and power before servicing. Tools needed: 1/4" hex driver, needle-nose pliers, multimeter (to verify microamp draw post-install). The sensor mounts with a single screw to the burner assembly; the wire connector snaps directly onto the control board harness.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
