Trane CNT1226 Ignition Module

The Trane CNT1226 Ignition Module is a critical OEM replacement part designed for precision burner management and flame safety in residential and light commercial gas-fired systems. As an authentic direct replacement for CNT01226, this module handles the critical sequence of operation, from timing the initial spark to continuous flame rectification. For technicians troubleshooting intermittent heating or "no heat" calls, the Trane CNT1226 provides the reliable 24V signal processing required to stabilize the ignition cycle and prevent nuisance lockouts. Built to rigorous Trane OEM specifications, this intermittent pilot ignition control ensures that gas valves and igniters operate within tight tolerances, protecting the heat exchanger from unburned fuel accumulation. Whether you are servicing a Trane or American Standard furnace, using a genuine HVAC ignition control module maintains the original engineering integrity and system efficiency. This industrial-grade electronic ignition module is engineered for high-duty cycles, offering the durability needed to handle the thermal stresses of modern high-efficiency HVAC equipment without the compatibility risks associated with universal aftermarket alternatives.

• Precise Flame Sensing: Utilizes advanced flame rectification technology to monitor matches and ensure the gas valve remains closed if no flame is detected.
• Direct OEM Compatibility: Specifically engineered as a drop-in replacement for the CNT01226, ensuring exact fitment and wiring alignment.
• Enhanced Safety Logic: Features integrated lockout protocols that stop the ignition sequence if the system fails to light after a specified number of trials.
• System Efficiency: Minimizes fuel waste by accurately controlling the pilot-to-main-burner transition timing throughout the heating cycle.

• Can the CNT1226 replace a universal ignition board? While universal boards exist, this OEM module is the exact match for specific Trane and American Standard models, ensuring all safety timings and internal resistance values meet the manufacturer's original design.
• How do I troubleshoot a lockout on this module? Verify that you have 24VAC at the power input and check for proper grounding. A common failure point is a dirty flame sensor or a faulty high-limit switch breaking the circuit before the module can energize the gas valve.
• What does it mean if the part number has changed? The Trane CNT1226 is the current production part number for older CNT01126 and CNT01226 units; it maintains the same electrical characteristics and form factor.
