OEM Carrier Hot Surface Igniter (LH33ZG001) for Model PG8MEA024045AAJA

This OEM hot surface igniter is the factory-specified replacement part for the Carrier PG8MEA024045AAJA packaged gas unit. During a call for heat, the igniter heats to over 2,000°F within seconds to ignite the gas burner. When it fails — due to cracks, contamination, or age-related degradation — the control board detects a failed ignition attempt and triggers a lockout, leaving you with no heat. Common symptoms include a furnace that attempts to start, cycles through the ignition sequence, then shuts off and flashes a fault code.

  • Part Number: LH33ZG001 | OEM Carrier hot surface igniter | Includes bracket and wiring harness
  • Igniter Type: Silicon nitride — the preferred modern igniter material offering superior durability, faster heat-up times, and longer service life vs. legacy silicon carbide igniters
  • OEM vs Generic: This is a genuine OEM Carrier part, factory-matched to exact resistance and geometry specifications for the PG8MEA024045AAJA. Generic aftermarket igniters may vary in resistance tolerance, tip geometry, and harness connector fit — risking premature failure or improper flame positioning.
  • Install Difficulty: 2/5 — De-energize the unit and allow the igniter to cool completely before removal. Never touch the igniter element with bare hands — skin oils cause hot spots and premature cracking. Tools needed: 1/4" nut driver, needle-nose pliers. Reconnect harness plug and verify ignition sequence before closing the unit.
  • Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier model PG8MEA024045AAJA packaged gas heating units. Verify your existing part number on the data plate or service manual before ordering. Our fitment team is available to confirm compatibility before you buy — no guesswork, no returns.

Frequently Asked Questions

Does this Igniter fit my Carrier PG8MEA024045AAJA?
Yes. This is the factory-specified OEM igniter for the Carrier PG8MEA024045AAJA. 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 PG8MEA024045AAJA?
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.
