Honeywell Q4100C9056 Ignitor

The Honeywell Q4100C9056 is a professional-grade silicon carbide hot surface igniter engineered for high-performance service replacement in 120 VAC gas-fired systems. Designed for maximum durability and resistance to burnout, this hot surface igniter features a 5.25-inch lead wire and a specialized receptacle connection with .093-inch male pins, ensuring a secure electrical interface. As a direct cross-reference for 138196P01 and 41-409N, this component is optimized for compatibility with LP and natural gas appliances from major manufacturers, including Amana, Trane, and Carrier. The flat-tip heating element and standard rib-offset mounting allow for precise positioning within the burner assembly, facilitating reliable ignition cycles in demanding residential and commercial environments. When performing a field swap, utilize the included bracket and hardware to maintain proper alignment and prevent premature failure due to vibration or thermal stress.

• Direct OEM Cross-Reference: Engineered to replace 138196P01, 41-409N, and common Robertshaw or White-Rodgers silicon carbide variants.
• Optimized Ignition Performance: High-density silicon carbide construction provides superior thermal conductivity and resistance to oxidation.
• Universal Fuel Compatibility: Fully rated for use with both Liquid Propane (LP) and Natural Gas furnaces and boilers.
• Rugged Electrical Lead: 5.25-inch lead wires with a 392?F insulation rating protect against high-temperature cabinet environments.
• Complete Installation Kit: Ships with the necessary bracket, screw, and wiring accessories to streamline furnace repairs.

Is the Q4100C9056 compatible with my furnace brand?
This 120V HSI is a universal service part that crosses to dozens of OEM numbers including IGN0030, LH33ZS001A, and B138196P01, making it compatible with brands like American Standard, Bryant, and Lennox.

How do I test if this silicon carbide igniter has failed?
After ensuring the unit is powered off, use a multimeter to check for continuity across the pins. A reading of "open" or infinite resistance typically indicates a cracked or burned-out heating element requiring replacement.

Can I touch the heating element during installation?
No. Skin oils can cause hot spots on the silicon carbide surface, leading to premature failure. Always handle the assembly by the ceramic block or the mounting bracket.
