OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JAA048070AGJA

This OEM hot surface igniter (part number LH33ZG001) is the factory-specified replacement for the Carrier PG8JAA048070AGJA gas furnace. The igniter is the critical first step in every heat cycle — it glows white-hot to ignite the gas burners. When it fails, the furnace's control board will attempt ignition, detect no flame, and lock out after 3 attempts, leaving your home without heat. Classic symptoms include the inducer running normally but no burner ignition, or an igniter that glows orange-red instead of bright white.

• Specs: OEM part number LH33ZG001 | Silicon nitride hot surface element | Factory-matched resistance and wattage | Direct plug-in harness connector — no splicing required
• OEM vs Generic: This is a genuine Carrier OEM igniter built to exact factory tolerances. Generic igniters often differ in element geometry, wattage draw, and ceramic composition, leading to premature cracking, inconsistent ignition, and shortened service life — especially on cold starts.
• Install difficulty: 2/5 — Turn off gas supply and 120V power at the disconnect before starting. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers. Never touch the silicon nitride element with bare hands — skin oils cause hot spots and premature failure. Use gloves or handle by the ceramic bracket only.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.
