OEM Carrier Flame Sensor LH680534 for Model CGH05012D Furnace

Keep your Carrier CGH05012D gas package unit firing safely with the genuine OEM LH680534 flame sensor. This flame-rectification rod confirms the burner has lit and signals the control board to keep the gas valve open—as carbon and oxidation coat the sensor over time, its microamp output fades, causing the unit to light then shut down on a flame-failure lockout. The result is intermittent no heat and annoying short cycling. Installing the exact Carrier-spec LH680534 restores a strong, stable flame signal and consistent heating on your CGH05012D. The replacement is an easy 15-minute repair: shut off power, remove the single mounting screw, disconnect the sensor lead, fit the new rod, and reconnect—no special tools needed, making this a confident DIY job. As a genuine OEM part it sits in the flame and reads precisely as Carrier intended. In stock now and ships same-day on orders placed before 3PM CST. Get safe, dependable ignition back in your unit fast.

Frequently Asked Questions

Does this flame_sensor fit my Carrier Model CGH05012D Furnace?
Yes. This is the factory-specified OEM flame_sensor for the Carrier Model CGH05012D Furnace. 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 Model CGH05012D Furnace?
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.
