Trane CNT1466 Ignition Control

The Trane CNT1466 is a professional-grade continuous retry ignition control designed for precise flame rectification sensing in residential and light commercial gas furnaces. Engineered as a genuine OEM replacement ignition module, this controller manages the heating cycle by monitoring the flame signal and initiating a sequence of retry attempts if pilot or main burner ignition fails to establish on the first cycle. Unlike standard 1-trial or 3-trial boards, the continuous retry logic provides superior uptime by persistently cycling the hot surface ignitor and gas valve until a stable flame is sensed or a critical safety limit is reached, effectively reducing nuisance furnace lockout codes on cold starts.

This 24V electronic ignition board integrates seamlessly into Trane and American Standard systems, acting as a direct-fit component that maintains the manufacturer’s original performance specifications. Integrated diagnostic LEDs assist technicians in identifying gas furnace troubleshooting issues quickly, from blocked flues to ignition failures. By ensuring a steady combustion sequence and managing the gas furnace ignition process with high-precision safety timings, the CNT1466 is the standard for service calls requiring a reliable, durable fix for failing furnace controls.

• Enhanced Reliability: The continuous retry logic reduces emergency callbacks caused by transient ignition failures and environmental lockouts.
• OEM Precision: Direct cross-reference for Trane CNT01466 ensures terminal-to-terminal compatibility without field modification.
• Integrated Diagnostics: Flashing LED fault codes streamline the diagnostic process, allowing for fast identification of system status.
• Consistent Performance: Engineered to withstand the high-temperature environment of the furnace control cabinet while maintaining accurate ignition timing.

• How do I resolve a lockout code with this board? Use the onboard LED flash code chart to determine if the lockout is due to flame failure, pressure switch issues, or internal component faults.
• Is this compatible with 80% and 90% AFUE units? Yes, the CNT1466 is utilized across multiple Trane gas furnace platforms; always verify your specific model and serial number before installation.
• What does "Continuous Retry" mean? If the hot surface ignitor fails to light the burner, the module will reset and attempt the ignition sequence again after a brief purge period, rather than permanently locking out the system immediately.
