Resideo Q4100C9046 Hot Surface Ignitor

Handle your next service call with the Resideo Q4100C9046, a field-proven 120V silicon carbide hot surface igniter designed for maximum durability in gas-fired furnaces and boilers. This high-temp HSI replacement features a robust ceramic block rated for 392°F (200°C), ensuring stable performance in both natural gas and liquid propane (LP) applications. The 19-1/8" lead length provides ample slack for complex cabinet routing, while the stripped-end wiring allows for fast integration into existing harnesses using standard wire nuts. Engineered with a standard right-edge rib and versatile bracket mounting, the Q4100C9046 serves as a direct cross-reference for several legacy components, including Norton 201N and Robertshaw 41-402N. Avoid unnecessary truck stock by utilizing this universal-fit solution that effectively eliminates the common failure points found in thinner, less resistant heating elements.

Key Benefits:

• Universal Compatibility: Serves as a direct technical replacement for 10755002, 1474-052, 201N, 902499, and 41-402N, simplifying inventory for service technicians.
• High-Temperature Resilience: The silicon carbide element is engineered to resist carbon buildup and physical degradation even at a sustained 392 degree temperature rating.
• Flexible Installation: Features a standard rib on the right edge and inclusive bracket mounting to accommodate multiple furnace burner configurations.
• Extended Reach: The 19 1/8 inch lead length ensures connectivity in large-scale residential and commercial heating units without the need for splicing additional wire.
• Multi-Fuel Support: Optimized for use in both Natural Gas and LP gas systems, maintaining consistent ignition across different fuel densities.

Common Questions:

Can the Q4100C9046 replace 80V or 24V igniters?
No, this component is strictly a 120 Vac hot surface ignitor. Installing a 120V element into a lower voltage system will result in inadequate heating and ignition failure.

What is the proper way to handle this silicon carbide igniter during installation?
Avoid touching the black element with bare hands. Skin oils can create hot spots on silicon carbide material, significantly reducing the operational life of the part.

Is this a direct fit for Norton or Robertshaw brands?
Yes, the Q4100C9046 is specifically designed as a high-performance field replacement for Norton 201N and Robertshaw 41-402N models, featuring the same electrical and physical mounting specs.
