OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JEA048090ABJA

This OEM hot surface igniter (part number LH33ZG001) is the factory-specified replacement for the Carrier PG8JEA048090ABJA gas furnace. The igniter is a critical component in the heating sequence — it heats to over 1800°F within seconds to light the burner assembly. When it fails, the furnace control board will attempt ignition, detect no flame, and enter a safety lockout, leaving you with a system that runs the inducer and then shuts down with no heat. Common symptoms include a furnace that clicks through the ignition cycle but produces no heat, or error codes indicating repeated ignition failure.

• Specs: Hot surface igniter | Silicon nitride element (preferred over silicon carbide for durability) | Factory OEM part number LH33ZG001 | Direct drop-in replacement — no modification required
• OEM vs Generic: This is a genuine Carrier OEM igniter, manufactured to exact factory specifications for proper wattage draw, element geometry, and mounting fit. Generic igniters often vary in element rating and physical dimensions, risking premature cracking or improper flame placement on the burner.
• Install Difficulty: 2/5 — Turn off gas supply and 120V power to the furnace before beginning. Tools needed: 1/4" nut driver, needle-nose pliers. Handle the igniter element only by its mounting bracket — skin oils will cause premature element failure. Allow the furnace to cool fully before removing the old igniter.
• Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.
