OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8MAA024070AEJA

This is the genuine OEM hot surface igniter for the Carrier PG8MAA024070AEJA packaged gas unit. During every call for heat, the control board energizes this igniter to glow to temperature and light the gas burner. When the igniter fails — due to cracking, contamination, or age-related resistance drift — the furnace will attempt ignition, fail to light, and lock out after one to three tries. The result: a system that appears to run but delivers no heat. Replacing this part with the correct OEM component restores factory ignition timing and burner reliability.

• OEM Part Number: LH33ZG001 | Genuine Carrier replacement | Includes bracket and wire harness for drop-in installation
• OEM vs Generic: OEM igniters are manufactured to exact resistance and thermal-cycling specifications required by the Carrier control board. Generic igniters often deviate in resistance tolerance, which can cause nuisance lockouts or premature failure — especially in high-cycle packaged unit applications.
• Install Difficulty: 2/5 — Always de-energize the unit at the disconnect before beginning. Do not touch the igniter element with bare hands — skin oils cause hot spots and early cracking. Tools needed: 1/4" nut driver, needle-nose pliers. Disconnect the harness plug, remove the single mounting screw, swap the igniter, reconnect, and verify ignition sequence through one full heat cycle.
• Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.
