OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8MAA048070ACJA

This OEM hot surface igniter (part number LH33ZG001) is the factory-specified replacement for the Carrier PG8MAA048070ACJA gas furnace. The igniter is a critical safety and ignition component — it heats to over 1,800°F within seconds to light the burner assembly each heating cycle. When the igniter fails, the furnace control board will attempt ignition, fail to sense a flame, and lock out the system, leaving you with no heat and a fault code on the board.

• Specs: Hot surface igniter | Silicon nitride element | Factory OEM part number LH33ZG001 | Direct plug-and-play connector for Carrier PG8MAA048070ACJA — no splicing required
• OEM vs Generic: This is a genuine Carrier OEM igniter, manufactured to exact factory resistance and thermal-shock tolerances. Aftermarket igniters frequently use lower-grade silicon carbide that cracks prematurely under thermal cycling, causing repeat failures within one to two heating seasons.
• Install Difficulty: 2/5 — Shut off gas supply and 120V power before beginning. Tools needed: 1/4" nut driver, flat-head screwdriver, work gloves. Never touch the igniter element with bare hands — skin oils cause hot spots and premature cracking. Photograph all wire routing before disconnecting.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
