OEM Carrier Flame Sensor LH680013 for Model PG9MAB024060ABSA

This is the OEM factory-specified flame sensor (part number LH680013) for the Carrier PG9MAB024060ABSA gas furnace. The flame sensor is a critical safety component — a small metal rod that uses microamp electrical current to verify that a flame is actually present after ignition. If the control board doesn't detect sufficient current through the sensor, it will cut gas flow as a safety measure, causing the furnace to shut down. A dirty, oxidized, or failed flame sensor is one of the most common causes of a furnace that lights briefly and then shuts off within 5 to 8 seconds, often triggering a lockout fault code.

• Specs: OEM part number LH680013 | Factory-matched rod geometry and ceramic insulator | Correct microamp output range for Carrier IFC compatibility | Direct drop-in replacement — no modification required
• OEM vs Generic: OEM flame sensors are precision-matched to Carrier's ignition control board microamp thresholds. Generic sensors may read outside tolerance, causing nuisance shutdowns or premature lockouts even when the burner is operating normally.
• Install Difficulty: 2/5 — Turn off gas and 120V power at the disconnect before beginning. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers, multimeter (to verify microamp reading post-install). The sensor is secured by a single screw and a single wire connector — a straightforward swap for any DIYer comfortable working inside a furnace cabinet.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as the direct OEM replacement for the Carrier PG9MAB024060ABSA gas furnace. Always verify your existing part number on the sensor's ceramic body or cross-reference your model's wiring diagram before ordering. Have a question about fitment?
