Resideo q4100c9052/u Hot Surface Igniter 120V Silicon Carbide

Product Description

The RESIDEO q4100c9052/u is a silicon carbide hot surface igniter engineered as a robust field-service replacement for gas-fired appliances that use 120-volt silicon carbide ignition systems. Part of the Q4100C series, this igniter is designed to consolidate multiple OEM igniter applications into a single replacement unit, reducing the number of SKUs a technician needs to stock. It operates at 120 volts and carries a temperature rating of 392 degrees F. The 5-inch lead length provides adequate wire reach in standard igniter mounting locations. Licensed HVAC technicians and gas appliance service professionals are the primary installers of this component.

This igniter is suited for residential and light-commercial gas-fired appliances, including furnaces and boilers, that rely on silicon carbide hot surface ignition in place of standing-pilot or spark ignition systems. It is compatible with both natural gas and liquid propane fuel types, making it a versatile inventory item for service technicians who work across multiple appliance configurations. The Q4100C series was developed specifically to serve as a broad cross-replacement for existing 120-volt silicon carbide igniter assemblies in the field.

Key Features

• Silicon carbide construction provides durability under repeated high-temperature ignition cycles
• 120-volt operating voltage matches standard hot surface ignition control circuits
• Compatible with both natural gas and liquid propane fuel types
• 5-inch lead length suits typical igniter mounting and wiring clearances
• Q4100C series designed as a broad field-replacement for 120 V silicon carbide igniters
• Temperature rating of 392 degrees F for reliable performance in gas appliance environments

Compatibility

Designed as a broad OEM-style replacement for gas-fired appliances equipped with 120-volt silicon carbide hot surface igniters, covering natural gas and liquid propane applications within the Q4100C series fitment range.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified gas appliance service professional in accordance with applicable local codes and the appliance manufacturer's service documentation. Always shut off power to the appliance and close the gas supply valve before removing the existing igniter. Silicon carbide igniters are fragile — handle only by the lead wires or mounting bracket and avoid touching the ceramic element with bare hands, as skin oils can cause premature failure. Verify supply voltage matches the igniter rating before restoring power.
