Frequently Asked Questions

Q: How do I know if my hot surface igniter is bad?
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.

Q: How long do hot surface igniters last?
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.

Q: Is the Q3400A1024 a direct replacement for the Q3400A1008?
A: Yes, the Resideo Q3400A1024 is the direct replacement for the Q3400A1008. The Q3400A1024 maintains the same electrical specifications, mounting configuration, and lead length, ensuring a straightforward swap in existing systems. Always verify compatibility with your specific furnace model and gas valve before ordering.

Q: Is the Q3400A1024 compatible with the Resideo SV9501M2528 gas valve?
A: Yes, the Q3400A1024 hot surface ignitor is designed to work with the SV9501M2528 and other Resideo SV9500 and SV9600 series SmartValve gas controls. This ignitor provides the ignition and flame sensing functions required by these modern gas valve systems.

Q: Can the Q3400A1024 replace the Q3400A1016 ignitor?
A: The Q3400A1016 has been superseded by Armstrong part number R42640-001, which is the current replacement part for that model. While both the Q3400A1024 and R42640-001 are hot surface ignitors with 30-inch leads, verify your furnace model and gas valve specifications to ensure the correct ignitor for your system.

Q: What is the difference between the Q3400A1024 and the Q3400A1032?
A: The Q3400A1024 is the replacement part for the Q3400A1032. Both ignitors share the same lead length, electrical requirements, and mounting configuration, allowing the Q3400A1024 to be used in systems originally equipped with the Q3400A1032.

Q: Is the Q3400A1024 compatible with the Resideo SV9570A2518 SmartValve?
A: Yes, the Q3400A1024 is compatible with the SV9570A2518 SmartValve. This ignitor works with the SV9500 and SV9600 series gas valves, including the SV9570A2518 model, providing reliable ignition and flame sensing for these systems.

Q: How do I install the Q3400A1024 hot surface ignitor?
A: Installation involves disconnecting power to the furnace, removing the old ignitor by disconnecting the wire leads and unscrewing the mounting bracket, then positioning the new Q3400A1024 in the same location and securing it with the mounting hardware. Connect the wire leads to the furnace control board, ensuring proper polarity and secure connections. Restore power and test the furnace through a complete heating cycle to verify proper ignition and flame sensing. Always follow the installation instructions provided with the ignitor and local electrical codes.

Q: What should I do if the Q3400A1024 ignitor glows but the furnace does not light?
A: If the ignitor glows but the furnace does not ignite, the issue is likely not with the ignitor itself. Check the gas supply to ensure the valve is open and gas is reaching the furnace. Verify that the gas valve is receiving the proper signal from the control board. Inspect the flame sensor for buildup or damage, as a dirty or faulty sensor can prevent the gas valve from opening even if the ignitor is functioning. If the ignitor glows for the proper duration and then the control board shuts off without ignition, the gas valve or control board may need service.
