Robertshaw 41-602 Mini Ignitor

The Robertshaw 41-602 Norton Mini Ignitor is a high-performance 120V hot surface ignitor engineered for precise ignition in modern residential and light commercial gas furnaces. Designed with a high-density recrystallized silicon carbide element, this Norton 41-602 igniter ensures rapid heat-up and long-term durability under harsh thermal cycling. It functions as a direct OEM furnace ignitor replacement for numerous brands, featuring 5-1/4" lead wires and a 1/4" female terminal connector for clean integration into existing control circuits. This silicon carbide hot surface ignitor operates at line voltage with a physical footprint optimized for narrow combustion chambers where standard ignitors may not fit. Technicians prefer the 41-602 for its consistent amperage draw and resistance to moisture-induced degradation. Ensuring correct HVAC furnace ignitor troubleshooting involves checking the terminal connections and verifying 120V at the inducer signal to confirm the 41-602 is receiving proper power for ignition.

• Universal Compatibility: Serves as a versatile 120V furnace ignitor replacement for a wide range of OEM furnace models.
• Rapid Heat-Up: Reaches ignition temperature within seconds to minimize gas valve dwell time.
• Durable Construction: High-density silicon carbide resists oxidation and thermal shock in demanding environments.
• Field Ready: Pre-stripped lead wires and universal mounting bracket facilitate fast installation during service calls.
• Precise Fit: Compact mini-ignitor profile allows for installation in tight heat exchanger configurations.

Is the 41-602 compatible with 80% and 90%+ AFUE furnaces?
Yes, as long as the system utilizes a 120V ignition control circuit. Always verify the voltage requirements before installation, as some modern systems use 80V or 24V ignitors.

Can I touch the ignitor element during installation?
No. Skin oils can create hot spots on the silicon carbide surface, leading to premature fracture. Always handle by the ceramic base or use clean gloves.

How do I test the Robertshaw 41-602 for failure?
Perform a continuity test using a multimeter. An open circuit (infinite resistance) indicates the element has failed, even if no visible cracks are present.
