White Rodgers 50A65-5165 Ignition Module

The White Rodgers 50A65-5165 is a professional-grade, microprocessor-based integrated furnace control designed as a high-performance direct replacement for CNT5165 and a wide range of Trane/American Standard single-stage ignition modules. Engineered for systems utilizing an 80V hot surface ignitor (HSI), this module manages the inducer motor, blower, gas valve, and spark-free ignition sequence with precision. It features a 24V input and provides dedicated 120V outputs for accessories like humidifiers and electronic air cleaners. This kit is a drop-in solution for Trane furnace board troubleshooting, offering diagnostic LED flash codes to identify flame failure, pressure switch trips, or open limits quickly. The 50A65-5165 includes dip-switch selectable fan-off delays (80/120/160/180 seconds) to optimize post-purge airflow and system efficiency. With integrated twinning capabilities and 5-amp fuse protection against low-voltage shorts, this ignition control module ensures reliable HVAC part compatibility for veteran technicians handling high-stakes residential and commercial furnace repairs.

• Universal Cross-Reference Compatibility: Operates as a direct OEM-style replacement for Trane CNT03076, CNT05164, CNT05165, and D341396P01, eliminating the need for field rewiring.
• Optimized Ignition Sequence: Employs an adaptive 0.8-second flame establishing time and a 2.0-second flame failure response time to maintain safe, steady burner operation.
• Advanced Error Recovery: Includes a system fault analysis logic that initiates automatic ignition retry upon sensing corrected conditions, reducing nuisance callbacks.
• On-Board Diagnostics: Rapidly troubleshoot furnace lockouts using the clear LED status indicator to interpret system-specific fault codes.
• Robust Protection: Features a 5-amp automotive-style fuse to shield the 24V transformer from accidental wiring shorts during installation or service.

• Can this module be used with a 120V ignitor? No. This specific control board is designed exclusively for 80V hot surface ignitors found in specific Trane and American Standard single-stage furnaces.
• How do I handle a 6-flash diagnostic code? A 6-flash code typically indicates 11 consecutive unsuccessful ignition attempts; verify gas supply, clean the flame sensor, and check the 80V HSI for continuity.
• Is this board compatible with twinning? Yes, the 50A65-5165 supports twinning applications provided the "TWIN" terminal is utilized on both boards for synchronized blower operation.
