Nordyne 921597 Heat Exchanger
The White-Rodgers 50A55-843 is a universal silicon carbide integrated ignition control designed for heavy-duty performance in single-stage gas furnaces. As a veteran-grade furnace control board, this module utilizes a microprocessor to provide constant surveillance of the gas burner, inducer, and circulator fan. It serves as a comprehensive 50A55-843 cross reference solution, replacing nearly all White-Rodgers 50A50 and 50A55 series modules, as well as numerous OEM controls from Trane, York, and Amana. This HVAC furnace circuit board features specialized terminals for 120V electronic air cleaners and humidifiers, ensuring full system integration. Built for 24V systems, it includes a replacement furnace ignition module kit with various wiring harnesses and jumpers to match unique field footprints, including specific Trane configurations.
Key Benefits- Extensive Compatibility: One-to-one replacement for over 100 OEM and aftermarket silicon carbide ignition models.
- Precision Diagnostics: On-board diagnostic LED flashes specific codes to identify pressure switch trips, limit string opens, or flame sensing failures.
- Field Adjustability: Selectable adjustable blower relay timings via dip switches allow for optimized heat and cool fan-off delays.
- Circuit Protection: Integrated 5-amp automotive-style fuse protects the low-voltage transformer from field-wiring shorts.
- Universal Installation: Includes a mounting template and additional wiring harnesses to adapt to diverse cabinet layouts.
What does a 3-flash code signal on this board?
In most applications, three flashes indicate a pressure switch that failed to close. This can stem from a restricted vent, a failing inducer motor, or a cracked static pressure line.
Can I use this board for nitride ignition systems?
No. The 50A55-843 is engineered specifically for silicon carbide igniters. Nitride systems require the 50A65 series to prevent premature igniter failure.
How do I handle the unique Trane wiring setup?
The provided White-Rodgers 50A55-843 manual details the use of the included jumper wires precisely for Trane-specific inducer and limit circuits to ensure proper safety string continuity.
