White-Rodgers 760-401 Electrode Sensor

This White-Rodgers 760-401 Electrode Sensor is a high-performance universal flame sensor designed for flame rectification in residential and commercial gas-fired furnaces. Built with a high-grade Kanthal flame rod, this component is engineered to withstand extreme combustion environments up to 1800°F (982°C) without oxidizing or degrading. The alumina ceramic insulator prevents high-voltage leakage to the chassis, ensuring that the microamp signal transmitted to the ignition control board remains consistent and accurate. This sensor comes equipped with a 30-inch Teflon-insulated lead wire rated for 250°C to handle tight cabinet routings and high-heat proximity. The 1/4-inch female spade terminal allows for an immediate, secure connection to existing wiring harnesses. As a veteran-grade HVAC replacement part, the 760-401 is compatible with Hot Surface Ignition (HSI) systems and can be remotely mounted on multiple burner banks or adjacent to the igniter. Replacing a fouled or cracked flame rod sensor with this unit is a standard solution for resolving persistent short cycling or furnace ignition failure in the field.

• Universal Compatibility: Replaces common OEM sensors from brands like Heil, Supco, and Packard, reducing the need for multiple SKUs on the truck.
• High-Temperature Durability: The Kanthal rod material ensures long-term conductivity even in high-output burner applications.
• Flexible Mounting: Features a single-screw, plated steel bracket that allows for precise positioning within the flame path for optimal flame sensing.
• Advanced Insulation: The Teflon-insulated lead protects against wire-to-casing shorts caused by vibration or excessive heat.

• What are the signs of a failing 760-401 sensor? The most common symptom is the burner igniting for 2–5 seconds and then immediately shutting down (proving failure). If the control board doesn't receive a DC microamp signal, it closes the gas valve as a safety measure.
• Can this sensor be cleaned? While technicians often use steel wool or a Scotch-Brite pad to remove carbon buildup, physical damage to the alumina ceramic or significant rod pitting requires a complete replacement to ensure reliable flame rectification.
• Is this sensor compatible with direct spark ignition? Yes, this unit is designed to work efficiently with both HSI and direct spark systems that utilize remote flame sensing.
