White-Rodgers 760-802 Flame Sensor

The White-Rodgers 760-802 Flame Sensor is a high-performance remote flame sensing solution engineered for Hot Surface Ignition (HSI) systems. Designed for reliability in demanding combustion environments, this remote flame sensor features a high-grade Kanthal flame rod capable of withstanding temperatures up to 1800°F. The assembly is secured with an alumina ceramic insulator to prevent electrical leakage and ensure accurate flame rectification signals to the ignition control module. For flexible field integration, it includes a 30-inch lead wire with high-temperature Teflon insulation rated for 250°C, terminating in a standard 1/4" female spade terminal. This HVAC replacement part is essential for maintaining the safety circuit, ensuring the gas valve remains closed if a flame is not detected during the ignition sequence. It is a direct fit for numerous gas-fired furnaces and heating appliances requiring remote sensing capabilities.

• Maximum Heat Resistance: The Kanthal flame rod and alumina ceramic insulator withstand extreme 1800°F temperatures without degradation.
• Universal Connectivity: Equipped with a 1/4" female spade terminal and a generous 30-inch Lead Length for versatile mounting on burners.
• Enhanced Safety: Provides the critical microamp signal required by HSI systems to verify flame presence and prevent hazardous gas accumulation.
• Durable Construction: Features a plated steel mounting bracket and Teflon-insulated wire to resist corrosion and thermal stress.

How do I test if the flame sensor is faulty?
Using a multimeter set to the μA (microamp) scale, measure the current in series with the sensor lead. A healthy White-Rodgers 760-802 should typically produce a steady signal above 1.0 microamp depending on the control module specifications.

Can this sensor be cleaned instead of replaced?
While surface oxidation can often be cleaned with a light abrasive (like steel wool), cracks in the alumina ceramic or significant pitting on the rod require immediate replacement to maintain system reliability.

Is this compatible with Spark Ignition systems?
This specific model is optimized for Hot Surface Ignition (HSI) applications. Always verify the mounting bracket and lead length against your existing OEM flame sensor before installation.
