Common Trane Furnace Error Codes and How to Resolve Them
Trane furnaces are known for their reliability and efficiency, but like any mechanical system, they can experience issues from time to time. When a problem occurs, the furnace’s control board will often display an error code to help diagnose the issue. In this article, we will explore some of the most common Trane furnace error codes and provide solutions on how to resolve them.
Error Code 126 – Ignition Failure
Error code 126 indicates an ignition failure in your Trane furnace. This error usually occurs when the furnace is unable to ignite the burners properly. One possible cause of this issue is a dirty or faulty flame sensor. The flame sensor is responsible for detecting whether a flame is present once the burners are ignited.
To resolve this error, start by turning off your furnace and locating the flame sensor. Carefully remove it and clean it using a soft cloth or fine-grit sandpaper to remove any accumulated dirt or debris that may be interfering with its function. Once cleaned, reinstall the flame sensor and turn on your furnace again. If the issue persists, it may be necessary to replace the flame sensor altogether.
Error Code 228 – Blocked Flue
Error code 228 indicates a blocked flue in your Trane furnace system. This error occurs when there is an obstruction in the flue vent that prevents proper ventilation of combustion gases. A blocked flue can pose serious safety risks as it can lead to carbon monoxide buildup.
To resolve this error, start by inspecting the flue vent for any visible obstructions such as debris or bird nests. If you notice any blockages, carefully remove them using gloves or a brush specifically designed for chimney cleaning.
If there are no visible obstructions but you still encounter error code 228, it is recommended to contact a professional HVAC technician. They will be able to conduct a thorough inspection of your furnace system, including the flue, and identify and resolve any underlying issues that may be causing the blockage.
Error Code 319 – High Limit Switch Open
Error code 319 indicates that the high limit switch in your Trane furnace has opened. The high limit switch is a safety feature that shuts off the furnace if it detects the temperature inside the unit reaching unsafe levels.
To resolve this error, start by checking for any airflow restrictions around your furnace, such as blocked vents or dirty filters. Ensure that all vents are open and unobstructed, and replace any dirty filters with clean ones.
If the error persists after ensuring proper airflow, it may indicate an issue with the high limit switch itself. In such cases, it is best to contact a professional HVAC technician who can diagnose and repair or replace the faulty switch.
Error Code 126 – Pressure Switch Stuck Open
Error code 126 indicates that the pressure switch in your Trane furnace is stuck open. The pressure switch is responsible for ensuring proper airflow within the furnace by monitoring pressure levels.
To resolve this error, start by inspecting all tubing connected to the pressure switch for any signs of damage or blockages. If you notice any issues with the tubing, repair or replace it accordingly.
Next, check if there are any obstructions in your exhaust vent or intake pipe that may be affecting pressure levels. Clear out any debris or blockages carefully to ensure unimpeded airflow.
If these steps do not resolve error code 126, it is recommended to contact an HVAC professional who can further diagnose and address the underlying issue causing the pressure switch to remain stuck open.
In conclusion, understanding common Trane furnace error codes can help homeowners troubleshoot and resolve issues promptly. However, if you encounter complex errors or are unsure about performing troubleshooting steps yourself, it is always best to seek professional assistance to ensure the safe and efficient operation of your Trane furnace.
