Resideo Q4100C9040 Hot Surface Ignitor

The Resideo Q4100C9040 Hot Surface Igniter is a field-proven 120 VAC furnace ignitor designed for professional-grade service and repair of gas-fired appliances. Constructed from high-durability silicon carbide, this component provides reliable ignition for both natural and LP gas systems. The unit features a wide ceramic mounting base with a right-rib offset, ensuring stable positioning within the burner assembly to withstand high-vibration environments. With a 392-degree temperature rating and 5 1/4" lead wires terminating in a receptacle with .093" male pins, it serves as a robust direct replacement for a wide range of OEM parts from Norton, Robertshaw, and White-Rodgers. Engineering focus on thermal shock resistance makes the Q4100C9040 a preferred choice for technicians needing a dependable HSI replacement that restores furnace efficiency and consistent ignition cycles without frequent service callbacks.

Key Benefits
  • Universal Compatibility: Engineered to replace various widespread 120V silicon carbide ignitors, reducing inventory overhead for service trucks.
  • Enhanced Thermal Stability: The premium silicon carbide construction is rated for 392°F (200°C), preventing premature element failure in high-output residential units.
  • Installation Ready: Includes a 5 1/4" lead length and standardized .093" male pins for seamless integration with existing wire harnesses.
  • Broad Gas Support: Verified for operation in both Natural Gas and Liquid Propane furnace configurations.
Common Questions

Is the Resideo Q4100C9040 compatible with my current furnace?
This 120V hot surface igniter is designed as a universal service part. You should verify the mounting bracket style and the .093" male pin connector type against your existing part. It is a frequent replacement for various Robertshaw and Norton models.

Can I touch the silicon carbide element during installation?
No. Like all silicon carbide ignitors, skin oils can create hot spots that lead to cracks. Always handle the unit by the wide ceramic mounting block to ensure the longest possible service life.

What is the primary cause of HSI failure in 120V systems?
Most failures occur due to physical damage, element oxidation, or voltage spikes. Replacing an old unit with the Q4100C9040 provides a refreshed resistance profile for more reliable ignition.
