OEM Carrier Flame Sensor LH33Z001 for Model GB3AAV036075AAJA

This OEM Carrier flame sensor (LH33Z001) proves the presence of burner flame on every heating cycle of your Carrier GB3AAV036075AAJA gas furnace. Set in the flame path, the rod returns a microamp signal to the control board to confirm ignition; if flame isn't detected, the board shuts the gas valve for safety. As the sensor oxidizes or cracks, the furnace will often light then drop out seconds later, producing nuisance short-cycling and no-heat complaints. This direct-fit replacement matches the factory specification for the GB3AAV036075AAJA, with the correct rod length and mounting position for accurate sensing. Installation is easy and takes around 15 minutes using a single mounting screw and one spade connector—no special tools required. Always switch off power at the breaker before working near the burners. Restore steady, safe ignition and stop frustrating lockouts with a genuine Carrier flame sensor. In stock and ships same-day when you order before 3PM CST.

Frequently Asked Questions

Does this flame_sensor fit my Carrier Model GB3AAV036075AAJA?
Yes. This is the factory-specified OEM flame_sensor for the Carrier Model GB3AAV036075AAJA. 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 GB3AAV036075AAJA?
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.
