How to Clear Trane Fault Codes: A Comprehensive Guide

Trane is a renowned manufacturer of heating, ventilation, and air conditioning (HVAC) systems, known for their reliability and efficiency. However, like any complex system, Trane HVAC units can sometimes encounter fault codes that require attention. In this comprehensive guide, we’ll explore the step-by-step process of clearing Trane fault codes for various models, providing you with the technical expertise and hands-on approach to troubleshoot and resolve these issues effectively.

Trane Sensor/Control BAYSENS119A

The Trane Sensor/Control BAYSENS119A is a crucial component in many Trane HVAC systems, responsible for monitoring and controlling various parameters. While there is limited information available on how to reset error codes specifically for this model, we can provide you with a few troubleshooting steps to try:

  1. Power Cycle the RTU: Begin by turning off the Rtu (Rooftop Unit) and waiting for at least 30 seconds. This allows the system to fully power down and reset. After the waiting period, turn the Rtu back on and observe if the error code persists.

  2. Check Wiring Connections: Ensure that all wiring connections between the BAYSENS119A sensor/control and the Rtu are secure and free from any damage. Loose or faulty connections can contribute to the occurrence of error codes.

  3. Inspect the Sensor/Control: Visually inspect the BAYSENS119A sensor/control for any signs of physical damage, such as cracks, corrosion, or water intrusion. If any issues are identified, the sensor/control may need to be replaced.

  4. Consult the Manufacturer: If the above steps do not resolve the issue, it’s recommended to consult the Trane technical support team or a qualified HVAC technician. They may be able to provide more specific guidance on resetting the error codes for the BAYSENS119A model.

Trane Gas Furnaces

Trane gas furnaces utilize an Integrated Furnace Control (IFC) system to manage various functions, including error code reporting. To clear fault codes on Trane gas furnaces, follow these steps:

  1. Locate the IFC: The IFC is typically located inside the furnace cabinet, often near the blower motor or control board.

  2. Interpret the Error Codes: Refer to the Trane gas furnace technical documentation or the IFC’s error code reference guide to understand the meaning of the displayed fault codes. This will help you identify the specific issue that needs to be addressed.

  3. Clear the Fault Codes: Depending on the furnace model, the process for clearing fault codes may vary. In some cases, you may need to power cycle the furnace by turning it off and then back on. In other cases, you may need to access a specific diagnostic mode or sequence to reset the error codes.

  4. Verify the Resolution: After clearing the fault codes, power cycle the furnace and observe if the error code reappears. If the issue persists, you may need to perform additional troubleshooting or contact a Trane service provider for further assistance.

It’s important to note that the specific steps for clearing fault codes on Trane gas furnaces may vary depending on the model and the version of the IFC. Refer to the manufacturer’s instructions or consult with a Trane-certified technician for the most up-to-date and accurate guidance.

Trane XV90 Furnace

Clearing fault codes on the Trane XV90 Furnace follows a specific sequence. Here’s how you can do it:

  1. Power Up the Control: Ensure that the control is powered up with the “G” terminal energized.

  2. Reset the Fault Codes: Apply “R” to the “W1” terminal three times within six seconds. The control will acknowledge the reset by turning on the red LED for two seconds.

  3. Verify the Resolution: After the reset process, power cycle the XV90 furnace and observe if the error code reappears. If the issue persists, you may need to perform additional troubleshooting or contact a Trane service provider for further assistance.

It’s important to note that clearing fault codes should only be done when servicing the furnace and a new code is expected. If the furnace is not running, clearing the codes will not help.
