OEM Carrier Flame Sensor with Wire (LH680014) for Model PG8UAA036045ACJA

This is the OEM factory-specified flame sensor with attached wire harness, part number LH680014, designed as a direct replacement for the Carrier PG8UAA036045ACJA gas furnace. The flame sensor is a critical safety component — it detects the presence of a burner flame by passing a small microamp current through the flame to ground. When the control board does not detect this signal, it cuts off gas flow as a safety measure. A dirty or failing flame sensor is one of the most common causes of a furnace that lights, runs for 5–8 seconds, and then shuts down in a lock-out condition. This OEM replacement ensures the exact microamp threshold and rod geometry specified by Carrier, restoring reliable ignition cycle performance.

  • Specs: OEM flame sensor rod with integrated wire harness | Factory-matched microamp detection threshold | Direct plug-in connector — no splicing required
  • OEM vs Generic: The OEM LH680014 includes the factory wire harness with the correct connector and wire gauge. Generic sensors often omit the harness or use thinner wire, introducing resistance that mimics a weak flame signal and causes nuisance lockouts.
  • Install Difficulty: 2/5 — Shut off gas and power before servicing. Tools needed: 1/4" hex driver or flat-blade screwdriver, fine steel wool or emery cloth (to clean rod if reusing), multimeter (to verify microamp signal post-install). Disconnect the wire harness, remove the single mounting screw, swap the sensor, and reconnect.
  • Warranty: 1-year OEM factory warranty. Orders ship same business day from our warehouse when placed before 3 PM local time.

Compatibility: Engineered specifically for the Carrier PG8UAA036045ACJA 80% AFUE gas furnace. Always verify the OEM part number on your existing sensor or equipment data plate before ordering. Not sure it fits? Our HVAC parts specialists will confirm fitment before you buy — no guesswork required. In stock and ships today.

How do I replace the flame sensor on my Carrier PG8UAA036045ACJA — LH680014?
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.
