OEM Carrier Hot Surface Igniter LH33ZS003 for Model CGH07512D

Bring dependable heat back to your Carrier CGH07512D gas package unit with the genuine OEM LH33ZS003 hot surface igniter. This silicon-nitride igniter heats white-hot to light the main burners on each heat cycle, and it's the leading cause of no-heat calls—when it cracks or weakens you'll get clicking, delayed lighting, or no flame at all. The factory-spec LH33ZS003 provides the exact resistance and rugged durability Carrier engineered into the CGH07512D, far outlasting fragile generic substitutes. Plan about 20 minutes for the swap: shut off power and gas, remove the burner access panel, unbolt the igniter bracket, unplug the connector, and install the new unit—handling it only by the ceramic base and never touching the element. A confident DIYer or any HVAC technician can handle this repair. Being a genuine OEM part, it mounts and ignites precisely as intended. In stock and ships same-day when you order before 3PM CST. Restore reliable heating to your CGH07512D.

Frequently Asked Questions

Does this Igniter fit my Carrier Model CGH07512D?
Yes. This is the factory-specified OEM igniter for the Carrier Model CGH07512D. 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 igniter on my Carrier Model CGH07512D?
Difficulty: Medium (20–30 min)
Step 1: Turn off power and gas. Step 2: Open furnace panel. Step 3: Locate igniter near burners. Step 4: Disconnect two-wire plug. Step 5: Remove mounting screw. Step 6: Install new igniter — do NOT touch element with fingers. Step 7: Reconnect, close panel, restore power/gas.
My furnace won’t ignite. What part is bad?
Furnace won’t ignite after the draft inducer runs = failed igniter. The hot surface igniter should glow bright orange within 60 seconds. No glow = cracked/burned out. Weak glow = degrading. Average lifespan: 3–7 years. Replacement: $15–$40 DIY.
Is this igniter 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 igniter?
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.
How fast does National HVAC Parts ship?
