Carrier LH33ZG001 Ignitor

The Carrier LH33ZG001 Ignitor is a high-performance silicon nitride hot surface ignitor designed for precise 120V ignition in Carrier, Bryant, and Payne gas furnaces. As a veteran technician knows, silicon nitride construction offers superior durability and faster heat-up times compared to older silicon carbide elements. This OEM-spec furnace replacement part features a cold resistance range of 40-90 ohms at room temperature, ensuring it integrates seamlessly with the furnace control board’s diagnostic parameters. The LH33ZG001 includes a pre-installed 2-pin Molex connector and high-temperature lead wires, facilitating a direct plug-and-play installation without the need for field modifications. When troubleshooting no-heat calls, this hot surface ignitor is the primary solution for restoring consistent burner ignition. Its robust design is engineered to withstand the thermal shock of thousands of heating cycles, maintaining stable resistance and reliable performance in demanding residential HVAC applications.

• OEM Compatibility: Exact replacement for Carrier, Bryant, and Payne part numbers LH33ZG001, 1176919, and IGN001.
• Durable Construction: Features a silicon nitride heating element that is more resilient to physical impact and oxidation than carbide alternatives.
• Technical Precision: Maintains steady-state current and specific ohm ratings required to prevent control board lockout.
• Simplified Service: Equipped with a standard Molex connector for rapid field replacement during emergency service calls.

• How do I test if my LH33ZG001 ignitor is faulty? Use a multimeter to check for continuity. A functional unit should show a cold resistance between 40 and 90 ohms; infinite resistance indicates the element is cracked or spent.
• Can I touch the ignitor element during installation? No. Skin oils cause hot spots on the surface, leading to premature failure. Only handle the part by the ceramic base.
• Does this include the mounting bracket? Yes, this unit comes with the necessary bracket and connector for standard furnace configurations.
