Resideo Q4100C9052 Hot Surface Ignitor
The Resideo Q4100C9052 Hot Surface Ignitor is a robust 120 Vac silicon carbide furnace igniter designed for consistent ignition in gas-fired heating systems. Engineered for use with both natural and LP gas, this direct replacement ignitor features a standard mounting configuration with a rib offset from the left edge, ensuring precise positioning within the burner assembly. With a 392-degree temperature rating and a high-durability carbide element, it provides the thermal shock resistance necessary for high-cycle HVAC applications. The lead length is 5 inches, terminating in a Molex front lock connector with .092 male pins for a secure electrical interface. For contractors performing preventative maintenance or emergency repairs, the Q4100C9052 offers a reliable solution for hot surface ignition troubleshooting, maintaining strict resistance tolerances to prevent nuisance lockouts. This Honeywell Resideo gas valve ignitor is built for field reliability, ensuring optimal heat transfer and rapid glow times during the combustion sequence.
- Silicon Carbide Construction: High-density material optimizes thermal conductivity and extends service life in high-temperature environments.
- Direct Fit Compatibility: Features a standard mounting bracket with a specific left-edge rib offset for simplified installation.
- Engineered Connector: Molex front lock connector with .092 male pins ensures a vibration-proof electrical connection to the ignition module.
- Gas Versatility: Fully rated for safe operation in both natural gas and liquid propane furnace configurations.
- Thermal Rating: Capable of withstanding a 392-degree ambient temperature rating at the lead transition point.
Common Questions
How do I check the resistance of the Q4100C9052?
Using a multimeter set to ohms, measure across the Molex pins at room temperature. A functioning silicon carbide ignitor typically reads between 40 and 75 ohms; significantly higher readings or an open circuit indicate the element has cracked or reached the end of its functional life.
Can I touch the black carbide element during installation?
No. Skin oils can create hot spots on the carbide surface, leading to premature failure. If contact occurs, clean the element with denatured alcohol before applying power.
Does this ignitor work with 80% and 90%+ efficiency furnaces?
Yes, provided the furnace uses a 120V ignition circuit and the mounting profile matches the burner box requirements. Always verify the connector pin diameter and lead length before installation.
