OEM Carrier Hot Surface Igniter LH33ZG002 for Model PG9YAA048080ACSS

This OEM hot surface igniter (part number LH33ZG002) is the factory-specified replacement for the Carrier PG9YAA048080ACSS gas furnace. The igniter is the first critical component activated in every heating cycle — the control board energizes it to glow at extreme temperatures, which then ignites the gas burner. When the igniter fails, the furnace will attempt to light, fail to sense flame, and enter a safety lockout — leaving you with no heat. Common symptoms include: the inducer motor runs, you hear a click from the gas valve, but the burners never light, followed by a lockout fault code.

• OEM Part Number: LH33ZG002 | Genuine Carrier replacement | Silicon nitride element | Factory-matched electrical connector for plug-and-play installation
• OEM vs Generic: This is an authentic OEM Carrier igniter built to factory tolerances. Aftermarket igniters often vary in wattage draw and element geometry, leading to unreliable ignition and shortened service life — especially in colder ambient conditions.
• Install Difficulty: 2/5 — Shut off gas and power before beginning. Tools needed: 1/4" nut driver, flat-head screwdriver, multimeter (to verify open element before replacement). Critical handling note: Never touch the silicon nitride element with bare hands — oils from skin cause hot spots that crack the element prematurely. Handle by the ceramic base only.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.
