OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JEA024045ABJA

This is the factory-specified OEM hot surface igniter (part number LH33ZG001) for the Carrier PG8JEA024045ABJA gas furnace. The hot surface igniter is the critical component responsible for lighting the gas burners on every heat cycle. When it fails — either through thermal fatigue, cracking, or contamination — the furnace control board will lock out after one or more failed ignition attempts, leaving you with no heat and typically a flashing fault code indicating ignition failure.

• Specs: OEM silicon nitride hot surface igniter | Factory-matched electrical resistance and warm-up timing | Engineered for exact bracket and mounting geometry of the PG8JEA024045ABJA — no modifications required
• OEM vs Generic: OEM igniters are manufactured to precise resistance tolerances and thermal cycling specifications. Generic or off-brand igniters often deviate in resistance values or physical fit, leading to premature failure, nuisance lockouts, or cracked elements during installation.
• Install Difficulty: 2/5 — Turn off power and gas supply before starting. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers. Never touch the igniter element with bare hands — skin oils cause hot spots that crack the element. Handle by the ceramic base or wiring harness only.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse when ordered before cutoff.
