Robertshaw 41-203 Ignitor

The Robertshaw 41-203 Ignitor is a heavy-duty hot surface ignitor engineered specifically for technical field replacements in both residential and commercial gas ranges and ovens. As a veteran-grade 501A type igniter, this unit maintains a consistent 120V AC electrical rating and is precision-calibrated to pull between 3.2 and 3.6 Amps. This tight amperage tolerance is critical for ensuring proper communication with the bi-metal gas safety valve, preventing delayed ignition or premature valve closure that often plagues inferior aftermarket components. Built for high physical and thermal strength, the 41-203 provides a silent, reliable strike even in high-cycle environments.

For contractors, the 11-1/2 inch lead length offers the necessary slack for clean routing through original wire paths, while the included high-temperature porcelain wire nuts facilitate a secure, heat-resistant connection. This Norton-style flat igniter features a robust mounting bracket for rapid alignment on the burner assembly. Whether you are servicing a standalone range or an industrial cooktop, the Robertshaw 41-203 is the professional choice for restoring factory-spec performance to the ignition sequence without compromising the integrity of the gas control system.

• Amperage Matching: Operates at 3.2-3.6 Amps to ensure seamless compatibility with standard bi-metal gas valves.
• High-Temp Leads: Features 11-1/2" lead wires with durable insulation designed for the extreme environment of a gas oven.
• Simplified Installation: Standard 501A configuration with included porcelain nuts for immediate field replacement.
• Industrial Grade Strength: Precision-manufactured for high thermal cycling to reduce premature fractures and brittleness.

Does this ignitor work with all gas valves?
The 41-203 is specifically designed to match 3.2 to 3.6 Amp bi-metal safety valves. Using it with a lower-rated (2.5-3.0 Amp) valve can lead to improper opening and is not recommended.

How do I verify if the 41-203 is failing?
Perform a continuity test. If the ignitor shows an open circuit (infinite resistance) or if the oven takes longer than 90 seconds to ignite while the glow bar is active, the component has likely reached its end-of-life.

Can I touch the ignitor element during installation?
No. As a technician, avoid touching the black silicon carbide element. Skin oils create "hot spots" that cause the material to fracture under thermal expansion during the first few cycles.
