OEM Carrier Hot Surface Igniter (LH33ZG001) for Model PG8MAA024045AFJA

This OEM hot surface igniter (part number LH33ZG001) is the factory-specified replacement for the Carrier PG8MAA024045AFJA packaged gas unit. During every heating cycle, the control board energizes this igniter to glow red-hot, igniting the gas burner the moment the gas valve opens. When the igniter fails — whether from age, thermal shock, or hairline cracks — the furnace will attempt ignition, fail to establish a flame, and enter a hard lockout, leaving you with no heat. Replacing it with the correct OEM part restores reliable ignition from the very first cycle.

  • Part Number & Type: OEM Carrier LH33ZG001 | Silicon Nitride hot surface igniter (Kyocera HSI) — the preferred modern igniter material for longer service life and lower watt draw versus older silicon carbide designs.
  • OEM vs Generic: This is the genuine OEM Carrier igniter, manufactured to exact factory geometry, resistance, and mounting specifications for the PG8MAA024045AFJA. Generic igniters may differ in element length or bracket angle, causing misalignment with the burner and nuisance lockouts.
  • Install Difficulty: 2/5 — De-energize the unit and allow the igniter to cool completely before removal. Never touch the nitride element with bare hands — skin oils cause hot spots and premature failure. Tools needed: 1/4" nut driver, needle-nose pliers. Disconnect the wire harness plug, remove the single mounting screw, and reverse to install. Verify ignition on first call for heat.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty. In-stock orders ship same business day from our warehouse — get your system back online fast.

Compatibility: Designed for the Carrier PG8MAA024045AFJA packaged gas heating unit. Verify part number LH33ZG001 on your unit's parts label or service manual before ordering. Need fitment confirmation? Our HVAC parts specialists verify compatibility before you buy — no guesswork, no returns.

Frequently Asked Questions

Does this Igniter fit my Carrier PG8MAA024045AFJA?
Yes. This is the factory-specified OEM igniter for the Carrier PG8MAA024045AFJA. 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 PG8MAA024045AFJA?
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?
