Replacement Control Board

Replacement HVAC Control Board for WHITE RODGERS 50E47-860 The White-Rodgers 50E47-860 is a microprocessor-controlled hot surface ignition control board engineered for reliable furnace system operation in residential and light commercial HVAC applications. This non-integrated module serves as a direct replacement for compatible models including X13130437070, providing complete ignition control, flame sensing, and system diagnostics in a single unit. This control board features advanced microprocessor technology that continuously monitors burner operation while maintaining safety through automatic flame detection and intelligent failure response protocols. The tri-colored LED indicator delivers real-time diagnostic feedback, enabling quick troubleshooting and system status verification by service technicians. The board supports both direct and indirect flame sense configurations with a minimum flame current requirement of 2 uADC and a non-detection threshold of 0.2 uADC, ensuring precise flame sensing accuracy. Maximum leakage resistance reaches 100 Mohm for reliable operation across varying furnace installations. Customizable program keys, color-coded A through F, allow technicians to adjust critical system timings including ignition retries, prepurge duration, and warmup cycles to match specific equipment requirements and operating conditions. This flexibility makes the board compatible with multiple furnace models while maintaining optimal performance parameters. Designed for professional installation and routine maintenance in commercial HVAC service applications, this control board delivers the reliability and precision required for 24/7 furnace operation in commercial buildings, industrial facilities, and multi-unit residential properties.
