OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8MAA024070ADJA

This is the factory-specified OEM hot surface igniter (part number LH33ZG001) for the Carrier PG8MAA024070ADJA packaged gas unit. The igniter is the first component activated during every heating cycle — the control board energizes it to reach ignition temperature, after which the gas valve opens and the burner lights. When the igniter fails, the furnace will attempt ignition, fail to light the burner, and enter a lockout fault — leaving you with no heat. A cracked element, high resistance reading outside the 45–70 ohm cold-resistance range, or visible carbon tracking are all signs it's time for replacement.

• Specs: 120V AC | Silicon Nitride element (preferred over silicon carbide for durability) | Cold resistance: 45–70 Ohms @ 75°F | Wire length: 9-1/4" | Total length with base: 2-1/2" | Includes mounting bracket
• OEM vs Generic: This OEM igniter is manufactured to Carrier's exact dimensional and electrical specifications by Kyocera — the original factory supplier. Generic igniters may vary in element geometry and resistance tolerance, risking premature cracking or inconsistent ignition timing.
• Install difficulty: 2/5 — De-energize the unit and allow the igniter to fully cool before removal. Tools needed: 1/4" nut driver, needle-nose pliers. Critical: Handle by the ceramic base only — never touch the silicon nitride element, as skin oils cause premature failure and void the warranty.
• Warranty: 1-year OEM factory warranty against manufacturing defects. In stock and ships same business day from our warehouse.
