Midco International 842957 Control Board
The Midco International 842957 Control Board, also identified as the S8670J3002 ignition module, is a high-performance intermittent pilot gas ignition control engineered for precision in 24Vac heating applications. As a veteran-grade furnace control board replacement, this microprocessor-based unit manages a safe start-up sequence, including a 30-second prepurge and a 15-second trial for ignition. Designed for use with both natural and LP gas, it coordinates the pilot burner spark and main gas valve operation while utilizing a advanced flame rectification circuit to monitor system safety. This OEM Midco 842957 circuit board is a direct drop-in for technicians servicing Midco burners and commercial heating systems, ensuring seamless integration with existing sensors and actuators. Built for 100% shutoff upon flame failure, it provides high-reliability performance in demanding HVACR environments where accurate timing and consistent spark generation are non-negotiable for system uptime.
Key Benefits for Technicians- Intermittent Pilot Control: Eliminates the need for a standing pilot, increasing overall system energy efficiency.
- Technical Precision: Features a 30-second prepurge and 15-second ignition trial to ensure safe combustion cycles.
- Universal Gas Compatibility: Engineered for industrial-grade performance with Natural or Liquid Propane (LP) systems.
- System Diagnostics: Integrated LED status indicator simplifies troubleshooting by providing real-time error codes and flame strength data.
- Robust Load Capacity: Rated for a 1.0A pilot and 2.0A main valve load at 24Vac.
What are the symptoms of a failing Midco 842957 control board?
Common indicators include intermittent stalling after 15-30 minutes of operation, failure to initiate the spark despite a call for heat, or the system entering immediate lockout. These issues are often caused by terminal corrosion or thermal stress on the internal microprocessor.
Does the S8670J3002 support local or remote flame sensing?
The S8670J3002 is a combination model typically supporting local flame sensing (single rod) but is versatile enough for various industrial machinery automation configurations where 24Vac control is required.
Can I use this board to replace older Honeywell S86 sequences?
Yes, this 842957 ignition module is a common replacement for legacy units like the S8670E, provided the timing and valve load specifications match your application’s requirements.
