OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JEA024045AAJA

This is the genuine OEM hot surface igniter (part number LH33ZG001) factory-specified for the Carrier PG8JEA024045AAJA packaged gas unit. During every call for heat, the igniter heats to over 1,800°F to light the gas burner. When it fails — due to cracking, contamination, or age-related resistance drift — the control board cannot confirm ignition, triggering a safety lockout. The most common symptom is a furnace that attempts to start, then shuts off completely with no heat delivered, often repeating 3 lockout attempts before going to hard lockout.

• Part Number: LH33ZG001 | Includes bracket and wiring harness | Factory-matched resistance and element geometry for reliable ignition sequencing
• OEM vs Generic: OEM igniters are manufactured to exact resistance tolerances required by the Carrier control board's ignition timing window. Generic igniters can vary in resistance and element thickness, leading to premature cracking or inconsistent hot-surface temperatures — resulting in repeat lockouts or shortened service life.
• Install Difficulty: 2/5 — Always de-energize the unit at the disconnect before beginning. Avoid touching the ceramic igniter element with bare hands; skin oils cause hot spots that crack the element. Tools needed: 1/4" nut driver, needle-nose pliers. Plug connector is keyed for correct polarity. Verify ignition sequence completes after reinstallation.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before cutoff.
