OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JAA024045AEJA

This is the genuine OEM hot surface igniter for the Carrier PG8JAA024045AEJA packaged gas unit. During every call for heat, the control board energizes this igniter to glow at extreme temperatures, igniting the gas burner within seconds. When it fails — typically from age, thermal fatigue, or physical cracking — the furnace will attempt ignition, fail to light, and enter a safety lockout. You'll get no heat and often a blinking fault code pointing directly to an ignition failure. Replacing the igniter with this factory-matched OEM part restores the proper resistance and wattage characteristics the control board expects.

• OEM Part Number: LH33ZG001 | Genuine Carrier replacement | Factory-matched resistance and wattage ratings for the PG8JAA024045AEJA
• OEM vs Generic: OEM igniters are manufactured to exact electrical specifications. Aftermarket igniters frequently vary in resistance and physical fit, risking premature failure, nuisance lockouts, or control board damage from mismatched draw.
• Install Difficulty: 3/5 — De-energize the unit at the disconnect before beginning. Never touch the igniter element with bare hands — skin oils cause hot spots that crack the element prematurely. Tools needed: ¼" nut driver, needle-nose pliers, multimeter (to verify resistance ~40–80 Ω). Reconnect wiring harness and confirm ignition sequence on first call for heat.
• Warranty: 1-year OEM manufacturer warranty. Ships same business day from our warehouse in factory-protective packaging.
