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.
