Hot Surface Ignitor with 30" Leads, Q3400A1024

The Resideo Q3400A1024 is a hot surface ignitor designed to provide reliable ignition for gas furnaces and heating systems. This ignitor features a 30-inch lead wire assembly, giving installers the flexibility to reach the gas valve even in installations where components are spaced farther apart. Built for use with Resideo SV9500 and SV9600 SmartValve systems, the Q3400A1024 delivers consistent, dependable performance in residential and light commercial heating applications. This ignitor serves as a direct field replacement for older Q3450 and Q3480 hot surface pilot burner assemblies, making it a versatile upgrade or repair part for many existing systems.

• 30-inch Lead Length: The extended 30-inch wire leads allow for flexible routing and easier connections in furnaces with widely spaced components, reducing installation time and simplifying service calls.
• Igniter Flame Rod Assembly: This integrated assembly combines the ignition element and flame sensing rod into one unit, streamlining installation and reducing the number of separate parts to manage during furnace maintenance.
• Compatibility with SV9500 and SV9600 SmartValves: Engineered specifically for use with Resideo SV9500 and SV9600 series gas valves, ensuring seamless integration with these modern control systems for dependable, safe operation.
• Field Replacement for Q3450 and Q3480 Systems: This ignitor directly replaces older Q3450 and Q3480 hot surface pilot burner assemblies, making it a straightforward upgrade or repair part that extends the service life of existing heating equipment.

The Q3400A1024 is designed for use with Resideo SV9500 and SV9600 series SmartValve gas controls. It serves as a field replacement for Q3450 and Q3480 hot surface pilot burner assemblies. This ignitor requires proper electrical connections to the furnace control board and must be installed according to the manufacturer's specifications to ensure safe, reliable ignition and flame sensing.

A: Signs of a failing hot surface ignitor include the ignitor not glowing when the furnace calls for heat, the furnace failing to light even though the ignitor appears to glow, or visible cracks or breaks in the ignitor element itself. If the ignitor does not glow at all, check the electrical connections and the control board output first. If the ignitor glows but the furnace does not ignite, the issue may be with the gas valve, gas supply, or flame sensor rather than the ignitor.

A: Hot surface igniters typically last between three and five years under normal operating conditions, though lifespan can vary based on usage frequency, furnace cycling patterns, and installation quality. Systems that cycle on and off more frequently or experience power surges may see shorter ignitor life. Regular furnace maintenance and proper electrical supply can help maximize ignitor lifespan.
