OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8MAA066110ACJA

This OEM hot surface igniter (part number LH33ZG001) is the factory-specified replacement for the Carrier PG8MAA066110ACJA packaged gas unit. During a call for heat, the control board energizes the igniter, which heats to over 1,800°F to light the gas burner. When the igniter fails — due to hairline cracks, contamination from oil or grease, or simple age — the furnace will attempt ignition, fail to sense flame, and lock out. You'll see a no-heat call with the inducer running but no burner ignition.

• Specs: 120V hot surface igniter | Silicon nitride element | Factory OEM replacement | Part No. LH33ZG001 | Approx. 0.07 lbs | Plug-and-play connector
• OEM vs Generic: This is the genuine Carrier OEM igniter, manufactured to exact resistance and element-geometry tolerances. Generic igniters often deviate in standoff geometry or resistance range, causing nuisance lockouts or premature failure in as little as one heating season.
• Install Difficulty: 2/5 — De-energize the unit and allow the igniter to cool completely before handling. Never touch the element with bare hands — skin oils will cause hot spots and early cracking. Tools needed: 1/4" nut driver, needle-nose pliers, and a multimeter to verify element continuity (typical cold resistance: 40–70Ω). Consult the service manual for the PG8MAA066110ACJA ignition sequence before reconnecting power.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before 3:00 PM ship same business day from our warehouse.
