OEM Carrier Hot Surface Igniter LH33ZG001 for Model PG8JAA036045AGJA

This is the genuine OEM hot surface igniter (part number LH33ZG001) factory-specified for the Carrier PG8JAA036045AGJA packaged gas unit. The hot surface igniter is a critical component in the ignition sequence — it heats to over 1,800°F within seconds to ignite the gas burner on every call for heat. When it fails, the control board will attempt ignition, detect no flame, and trigger a safety lockout, leaving you with no heat. Common symptoms include the system going through ignition attempts and shutting down, the inducer running but no burner lighting, or a visible crack in the igniter element.

• Specs: 120V AC | Silicon nitride element (preferred over silicon carbide for durability) | OEM part number LH33ZG001 | Approximate resistance: 40–75 Ω cold
• OEM vs Generic: This is a genuine Carrier OEM igniter manufactured to exact factory tolerances. Aftermarket igniters can vary in element geometry and resistance, causing delayed ignition timing, nuisance lockouts, or premature failure — especially in cold-start conditions.
• Install Difficulty: 2/5 — Always de-energize the unit at the disconnect before starting. Do not touch the igniter element with bare hands — skin oils cause hot spots that crack the element. Tools needed: 1/4" and 5/16" nut drivers, Phillips screwdriver. Disconnect the plug harness, remove the mounting screw, swap the igniter, and verify ignition on the next heating cycle.
• Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse when ordered before cutoff.
