OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JAA036070ACJA

This is the factory OEM hot surface igniter for the Carrier PG8JAA036070ACJA packaged gas unit. During a call for heat, the control board energizes the igniter to glow at approximately 2,000°F, igniting the gas burner. When the igniter fails — whether from thermal fatigue, hairline cracks, or contamination — the furnace initiates its ignition sequence but the burner never lights, triggering a hard lockout fault after 2–3 attempts. Replacing the igniter with this exact OEM part restores reliable, factory-matched ignition performance.

• OEM Part Number: LH33ZG001 | Includes factory bracket and wiring harness for drop-in installation | Silicon nitride element for longer service life vs. older silicon carbide designs
• OEM vs Generic: This OEM igniter is manufactured to Carrier's exact resistance and wattage specifications. Generic igniters often fall outside tolerance, causing nuisance lockouts or premature failure within one heating season.
• Install Difficulty: 2/5 — Disconnect power and gas before starting. Tools needed: 1/4" nut driver, needle-nose pliers. Never touch the igniter element with bare hands — skin oils accelerate failure. Disconnect harness, remove mounting screw, swap igniter, reconnect harness, and verify ignition sequence on first call for heat.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
