OEM Carrier Straight Flame Sensor LH680013 for Model PG9MAB060120ACSA

This is the factory OEM flame sensor (part number LH680013) for the Carrier PG9MAB060120ACSA gas furnace. The flame sensor is a critical safety component: its straight sensing rod passes a small electrical current through the burner flame to verify ignition. When the rod detects a live flame, it signals the control board to keep the gas valve open. When it fails — typically due to oxidation or carbon buildup on the rod — the furnace will light briefly, then shut off after 5 to 8 seconds, often going into repeated lockout cycles. Replacing this inexpensive part is one of the most common and cost-effective furnace repairs available.

• Specs: Straight flame sensing rod | 3-1/4 inch rod length | Wire lead included | Replaces LH33WZ514 and LH33WZ516
• OEM vs Generic: This is a genuine OEM part manufactured to Carrier factory specifications. OEM sensors deliver precise microamp output within the control board's designed threshold — off-brand sensors with inconsistent rod coatings can cause nuisance lockouts or fail prematurely.
• Install Difficulty: 1/5 — One of the simplest furnace repairs. Tools needed: 1/4" hex driver or nut driver, fine steel wool or emery cloth (to clean rod if reusing bracket), multimeter (optional, for microamp verification). Always turn off power and gas before servicing.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG9MAB060120ACSA gas furnace. This part also cross-references superseded part numbers LH33WZ514 and LH33WZ516.
