Honeywell Q4100C9068 HSI

The Honeywell Q4100C9068 is a professional-grade silicon carbide hot surface igniter (HSI) engineered for reliable field service replacement in 120 VAC gas-fired appliances. This robust 120V igniter features a durable ceramic insulator with a standard rib offset, designed to withstand the high-heat cycles of modern furnaces and boilers. The 5.25-inch lead wires are rated for 200?C (392?F) and terminated with a receptacle connection containing 0.093-inch male pins, ensuring a secure electrical interface. As an industry-standard component, the Q4100C9068 is a direct cross-reference for the Norton 41-405N and Robertshaw 271D, making it a versatile addition to any technician's truck stock for repairing residential and light commercial heating systems.

• Universal Compatibility: Serves as a direct 120V replacement for Norton 41-405, White-Rodgers 767A-361, and Robertshaw series igniters.
• High Thermal Strength: Constructed from high-purity silicon carbide to provide stable electrical resistance and resist premature burn-out.
• Secure Integration: Outfitted with 18-gauge nickel chrome lead wires and high-temperature fiberglass insulation for maximum conductivity.
• Installation Ready: Includes the necessary mounting bracket and screw to adapt the igniter to specific burner box configurations.

How do I test if the Q4100C9068 has failed?
Perform a resistance test using a multimeter set to Ohms at room temperature. A typical silicon carbide igniter should show a measurable resistance; an infinite reading (open circuit) or visible cracks on the element indicate a failure. Also, verify that the control board is delivering 120 VAC to the harness during the ignition trial.

Can I touch the igniter element during installation?
No. Avoid touching the black carbide element with bare hands. Skin oils can create hot spots that lead to premature failure. Always handle the part by the ceramic block or the mounting bracket.

What if the connector does not match my furnace harness?
If the pre-installed 0.093-inch male pin receptacle does not match, the leads can be cut and spliced using ceramic wire nuts, provided the lead length is sufficient to stay clear of the burner flame.
