OEM Carrier Flame Sensor LH33ZS003 for Model GB1AAV036035AAJA

This OEM Carrier flame sensor (LH33ZS003) verifies successful burner ignition on your Carrier GB1AAV036035AAJA furnace, telling the control board it is safe to keep the gas valve open. Through flame rectification it detects the burner flame within seconds of ignition; when the rod becomes coated with oxide or corrodes, the furnace lights for a moment then shuts off and tries again, producing the classic short-cycling no-heat symptom. Manufactured to exact Carrier specifications, this sensor provides a clean, strong microamp signal for steady, dependable operation. Installation is easy and takes most technicians 10-15 minutes: cut power, remove one mounting screw, disconnect the lead, and install the new sensor. Avoid touching the metal rod with bare hands. Genuine OEM parts ensure proper signal strength and protect your warranty. In stock right now — orders placed before 3PM CST ship the same day. Stop frustrating burner cycling and restore consistent heat with the exact flame sensor Carrier designed for this furnace.

Frequently Asked Questions

Does this flame_sensor fit my Carrier Model GB1AAV036035AAJA?
Yes. This is the factory-specified OEM flame_sensor for the Carrier Model GB1AAV036035AAJA. 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 GB1AAV036035AAJA?
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.
