OEM Carrier Flame Sensor with Lead LH680534 for Model PG96VAT66120DDAA

This is the factory OEM flame sensor with lead wire for the Carrier PG96VAT66120DDAA 96% AFUE two-stage gas furnace. The flame sensor is a critical safety component — its rod is submerged in the burner flame and generates a small microamp (µA) DC signal that tells the integrated furnace control (IFC) board that combustion is actually occurring. If the sensor is coated with oxidation or has failed, the board cannot confirm a flame and will shut off the gas valve within 5–8 seconds of ignition as a safety lockout. The furnace will typically attempt ignition 3 times before going into hard lockout, requiring a manual reset.

  • Specs: OEM part number LH680534 | Includes pre-attached lead wire for direct plug-in replacement | Factory-matched µA output | Compatible with Carrier IFC board signal threshold
  • OEM vs Generic: This OEM unit ships with the correct rod geometry, ceramic insulator rating, and lead wire gauge specified by Carrier engineering. Generic sensors may produce weaker µA signals, causing nuisance lockouts even with a clean flame.
  • Install Difficulty: 1/5 — One of the easiest furnace repairs. Tools needed: 1/4" hex driver or nut driver, fine steel wool or emery cloth (for light oxidation cleaning). Always shut off gas and power at the disconnect before servicing. Plug in the lead wire connector and secure with a single screw.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Ships same business day from our NationalHVACParts.com warehouse.

Compatibility: Designed specifically for the Carrier PG96VAT66120DDAA packaged gas furnace. Always verify OEM part number LH680534 against your unit's data plate or existing component before ordering. Our parts specialists are available to confirm fitment — order with confidence and get back to heat fast.

Frequently Asked Questions

Does this Flame Sensor fit my Carrier PG96VAT66120DDAA?
Yes. This is the factory-specified OEM flame sensor for the Carrier PG96VAT66120DDAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the flame sensor on my Carrier PG96VAT66120DDAA?
Difficulty: Easy (10–15 min)
Step 1: Turn off power/gas. Step 2: Open furnace panel. Step 3: Locate flame sensor rod near burners. Step 4: Remove single mounting screw. Step 5: Clean rod with 400-grit sandpaper until shiny (or replace). Step 6: Reinstall and tighten. Most common furnace repair — saves $150–$300 vs technician.
My furnace lights then shuts off after a few seconds. Why?
Furnace lights then shuts off after 3–10 seconds = dirty flame sensor in 90% of cases. The sensor can’t detect flame through oxidation buildup. Fix: clean with 400-grit sandpaper (free, 15 min). If cleaning doesn’t work, replace the sensor.
Is this flame sensor compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier flame sensor?
OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
