OEM Carrier Flame Sensor LH680534 for Model PG96VAT60080CAAA Furnace

This is the genuine OEM Carrier flame sensor (part number LH680534, with lead) — the current factory-authorized replacement for the discontinued LH33WZ521. The flame sensor is a critical safety component in your Carrier PG96VAT60080CAAA 96% AFUE gas furnace. It uses electrical conductivity through the burner flame to confirm ignition and signal the control board to keep the gas valve open. When the sensor becomes coated with oxidation or fails outright, the furnace will light briefly then shut down after 5–8 seconds, triggering a lockout fault — leaving you without heat.

• Part Numbers: OEM part LH680534 (Flame Sensor w/Lead) | Supersedes discontinued part LH33WZ521 | Direct factory-authorized upgrade with pigtail lead pre-attached
• OEM vs Generic: This is a genuine Carrier OEM sensor, not an aftermarket copy. OEM sensors are calibrated to the exact microamp threshold required by the Carrier IFC control board. Generic sensors frequently fall outside tolerance, causing nuisance lockouts or premature failure — especially in high-efficiency condensing furnaces like the PG96VAT series.
• Install Difficulty: 2/5 — Turn off power and gas before beginning. Tools needed: 1/4" hex driver or nut driver, needle-nose pliers, and a multimeter (to verify microamp draw post-install). Disconnect the single wire lead, remove the one mounting screw, and reverse to install. Tip: lightly sand the rod with fine steel wool before installation if reusing the bracket.
• Warranty: 1-year OEM manufacturer's warranty against defects. Orders ship same business day from our warehouse when placed before cutoff.
