Honeywell Q4100C9058 HSI

The Honeywell Q4100C9058 is a high-performance Silicon Carbide Hot Surface Igniter engineered for rugged field service replacement in gas-fired furnaces, boilers, and water heaters. Designed for 120 VAC systems, this igniter serves as the primary direct cross for B144676P01, 767A-377, and 41-410 models. It features 4.5-inch lead wires with a specific Molex front lock connector utilizing 0.092" male pins, ensuring a secure electrical interface that resists vibration and thermal expansion cycles common in high-efficiency combustion chambers.

For technicians managing multi-brand service fleets, the Q4100C9058 simplifies inventory by providing a robust 120V HSI replacement that meets OEM strike plate alignment requirements. The silicon carbide element is manufactured for high thermal conductivity and rapid ignition, typically reaching operational temperature within 17 seconds. This assembly includes the necessary mounting bracket and hardware to adapt to various burner box configurations, maintaining critical clearances from other appliance components to prevent premature element stress or grounding issues.

• OEM Compatibility: Direct replacement for B144676P01, 271N, and IG410 across Amana, Trane, and York systems.
• Precision Connection: Integrated Molex connector with 0.092" pins eliminates the need for field splicing in standard 4.5-inch lead applications.
• Thermal Stability: High-purity silicon carbide design ensures consistent resistance readings and reliable ignition in both Natural and LP gas environments.
• Installation Ready: Includes universal mounting bracket and hardware to facilitate secure positioning within the burner assembly.

What are the specific electrical requirements for this igniter?
The Q4100C9058 operates on a standard 120 VAC circuit. It is rated for temperatures up to 392?F at the ceramic base, making it suitable for high-heat residential and light commercial gas-fired appliances.

How do I verify if the Q4100C9058 is the correct replacement?
Check your existing component for a matching ceramic block style or lead length. This model is specifically calibrated as a direct cross for B144676P01. If the furnace harness does not match the Molex connector, ensure sufficient lead length before adapting the wiring.

Can this igniter be used in sealed combustion units?
Yes, provided the ceramic block properly maintains the burner box seal. Always verify that the bracket offset and rib alignment match the original equipment to ensure the element path is correctly positioned in the gas flow.
