OEM Carrier Hot Surface Igniter (LH33ZG002) for Model PG9YAA060100ACSS

This is the genuine OEM Carrier hot surface igniter, part number LH33ZG002, factory-specified for the Carrier PG9YAA060100ACSS gas furnace. The hot surface igniter is the first component activated during every heating cycle — the control board energizes it to glow at extreme temperatures, igniting the gas burner within seconds. When it fails, the furnace will attempt ignition, fail to sense a flame, and enter a safety lockout — leaving your home without heat. Common symptoms include repeated ignition attempts with no heat, a blinking fault code for lockout, or a visibly cracked or broken igniter element.

• Part Number: LH33ZG002 | OEM Carrier replacement | Silicon nitride construction | 120V | Compatible with Carrier PG9YAA060100ACSS packaged gas furnace
• OEM vs Generic: This genuine Carrier OEM igniter is manufactured to exact factory tolerances for current draw and warm-up time. Generic igniters often vary in resistance and geometry, causing nuisance lockouts and shortened service life.
• Install Difficulty: 2/5 — Shut off power and gas before beginning. Tools needed: 1/4" nut driver, needle-nose pliers. Critical: Handle by the ceramic harness bracket only — never touch the silicon nitride element. Skin oils will cause premature cracking and failure under heat cycling.
