OEM Carrier Flame Sensor w/ Wire LH680014 for Model PG8DAA036050ACJA

This is the factory OEM flame sensor with wire harness for the Carrier PG8DAA036050ACJA packaged gas furnace. The flame sensor — also called a flame rod — is a critical safety component that detects the presence of a burner flame by passing a small microamp current through the flame and into the ground. When the sensor's rod becomes coated with oxidation or carbon buildup, resistance increases and the control board can no longer verify flame presence, causing the furnace to lock out. The most common symptom is a furnace that lights, runs for 5–8 seconds, then shuts off — repeating 3 times before going into hard lockout.

• Specs: OEM part number LH680014 | Includes integrated wire harness | Factory-matched microamp sensitivity | Compatible with Carrier packaged gas furnace control board
• OEM vs Generic: This OEM unit is manufactured to exact factory tolerances for microamp signal output and rod geometry. Generic sensors may produce borderline readings that cause nuisance lockouts or premature failure under variable flame conditions.
• Install Difficulty: 2/5 — Turn off gas supply and 120V power before servicing. Tools needed: 1/4" hex driver or screwdriver, needle-nose pliers, optional multimeter (to verify microamp draw post-install). Disconnect the wire harness, remove the single mounting screw, and reverse to install. Clean the burner port area before reinstalling.
