Carrier LH33ZG002 Ignitor
Ensure reliable ignition for your residential or light commercial furnace with the Carrier LH33ZG002 Hot Surface Ignitor. This heavy-duty silicon nitride ignitor is engineered as a direct OEM replacement for a variety of Carrier, Bryant, and Payne gas furnaces and unit heaters. Unlike older silicon carbide components, this 120V HVAC igniter features a robust, non-porous surface that offers superior resistance to oxidation and mechanical stress. The Carrier LH33ZG002 delivers a rapid warm-up time to quickly reach the required 1200°C for stable gas ignition, maintaining consistent cold resistance of 34-64 ohms at room temperature. Its durable 3-inch element and base assembly, paired with a 6.25-inch lead, allow for seamless integration into existing burner assemblies. This furnace ignition part is a critical maintenance item for technicians aiming to restore heating efficiency and prevent nuisance lockouts caused by high-resistance or cracked elements in modern high-efficiency HVAC equipment.
Key Benefits- Enhanced Durability: The advanced silicon nitride construction is significantly less brittle than carbide alternatives, reducing the risk of fracture during handling or combustion cycles.
- Direct OEM Fit: Designed to replace factory-installed units in Carrier 359AAV, 58HDV, and PG9M series, matching original mounting bracket dimensions and electrical connectors.
- Efficient Performance: Optimized power consumption with a steady-state current draw designed to interface correctly with the integrated furnace control board.
- Reliable Cold Starts: Maintains stable ohm ratings, ensuring the control board detects proper resistance for safe gas valve activation.
Can I use the Carrier LH33ZG002 to replace a silicon carbide ignitor?
Yes, silicon nitride ignitors are often used as high-performance upgrades for carbide parts if the physical mounting and 120V rating match. This unit provides a longer service life and better resistance to thermal shock.
What should the resistance reading be for a new LH33ZG002?
A healthy Carrier LH33ZG002 typically displays a cold resistance between 34 and 64 ohms when tested at 75°F. If your meter shows "OL" or significantly higher resistance, the element is failed and requires replacement.
Is handling the element problematic?
While silicon nitride is more durable, it is best practice for technicians to handle the part by the ceramic base only. Contaminants or skin oils can create hotspots that reduce the longevity of the element.
