OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8MAA024070ACJA

This OEM hot surface igniter (part number LH33ZG001) is the factory-specified replacement for the Carrier PG8MAA024070ACJA gas furnace. The igniter is the first active component in every heat cycle — the control board energizes it to reach surface temperatures exceeding 1,800°F, which then ignites the gas flowing from the burners. When it fails, the furnace will attempt ignition, fail to light, and enter a lockout sequence — leaving you with no heat. Common symptoms include repeated ignition attempts with no flame, a cracked or visibly broken igniter element, or a fault code on the control board indicating ignition failure.

• Specs: Silicon nitride hot surface igniter | OEM part number LH33ZG001 | Factory-matched voltage and wattage | Direct plug-in connector for Carrier PG8MAA024070ACJA
• OEM vs Generic: This is a genuine OEM Carrier igniter manufactured to exact factory specifications. Generic igniters often deviate in wattage and surface temperature, leading to nuisance lockouts, premature cracking, and shortened service life — especially in cold-start conditions.
• Install difficulty: 2/5 — Turn off gas supply and 120V power at the breaker before beginning. Tools needed: 1/4" or 5/16" nut driver, needle-nose pliers. Never touch the igniter element with bare hands — skin oils cause hot spots that crack the element prematurely. Use gloves or handle only by the ceramic bracket.
• Warranty: 1-year OEM factory warranty against defects. Ships same business day from our warehouse when ordered before 3 PM local time.
