Resideo Q4100C9042 Hot Surface Ignitor
The Resideo Q4100C9042 Hot Surface Ignitor is a heavy-duty 120V silicon carbide replacement designed for high-performance ignition in gas-fired furnaces and boilers. This HVAC furnace ignitor serves as a robust field service solution, engineered to withstand high operating temperatures with a 392°F temperature rating. It features a standard mounting configuration with a rib on the right edge and a 5.5-inch lead length, ensuring compatibility with various burner box orientations. The Molex internally keyed connector with 0.084-inch male pins provides a secure, vibration-resistant electrical path. This technician-grade HSI replacement is built for longevity, offering high resistance to burn-out and physical damage during the ignition cycle. Professional installation is recommended to ensure proper alignment and seal within the combustion chamber, maintaining the efficiency of natural gas or LP systems.
Key Benefits:- Universal Compatibility: Specifically designed to replace popular 120 Vac silicon carbide ignitors from Robertshaw, White-Rodgers, and Norton.
- Thermal Durability: High-density silicon carbide construction maintains structural integrity up to a 392 degree temperature rating.
- Secure Integration: Includes an internally keyed Molex connector with .084" pins for a precise, "plug-and-play" fit in compatible harnesses.
- Versatile Fuel Support: Optimized for reliable spark-to-flame transitions in both natural gas and liquid propane appliances.
What causes a hot surface ignitor to fail?
Most failures occur due to "hot spots" created by skin oils from handling the element or natural degradation of the silicon carbide over time. Cracks in the ceramic or element usually indicate it is time for a Q4100C9042 replacement.
How do I check if my ignitor is receiving power?
Set your multimeter to 300 VAC and probe the Molex connector pins during the furnace's call for heat sequence. You should see a steady 120V signal before the gas valve opens.
Can I use this for an LP furnace?
Yes, the Resideo Q4100C9042 is fully rated for use with both natural and LP gas systems, provided the mounting rib orientation matches your original bracket.
