The Robertshaw 41-604 Norton Mini Ignitor is a high-performance 120V AC hot surface igniter engineered for precision and rapid ignition in gas-fired heating systems. This 120V gas burner igniter features a distinctive 4-inch (102mm) ceramic block design and is constructed from a non-porous, high-strength material that ensures consistent thermal transfer. Optimized for a 3-second heat-up time, the 41-604 provides reliable flame initiation in compact burner compartments. It comes equipped with 18 AWG lead wires measuring 6-1/8 inches and a 1-480699-0 locking connector housing for a secure electrical interface. As a versatile hot surface mini ignitor, it serves as a direct HVAC 41-604 replacement for several OEM components, including Armstrong Air 44744-2, White-Rodgers 767A-378, and Norton 601XBM. For service technicians, this unit offers a robust solution for troubleshooting furnace ignition failures, maintaining high resistance stability across repeated high-temperature cycles. Key Benefits Rapid Ignition: Reaches operating temperature within 3 seconds for efficient gas sequence starts. OEM Compatibility: Replaces common industry parts from Armstrong, York, and White-Rodgers. High-Temperature Durability: Engineered with non-porous 18-gauge nickel chrome lead wires and fiberglass insulation. Small Footprint: Designed for tight gas furnace burner configurations common in newer high-efficiency units. Secure Connection: Features a factory-installed locking connector to prevent vibration-induced disconnects. Common Questions What is the typical resistance for the 41-604 igniter? When testing with a multimeter, this hot surface igniter should typically show a resistance reading between 30 and 200 ohms at room temperature. A reading of infinity indicates a cracked or failed element. Can I touch the igniter element during installation? No. Skin oils can create hot spots on the silicon nitride/carbide surface, leading to premature failure. Always handle the unit by the 4-inch ceramic block. Does this unit work with 80V or 240V systems? This is a dedicated 120V AC furnace ignitor. Using it in systems with a different voltage output from the ignition module will cause immediate component failure.
