What is Trane Furnace Code 5
If you notice Trane furnace code 5 on your heating system, the first step is to turn off the power to the furnace to ensure your safety. Then, follow the steps outlined in your furnace manual to reset the control module unit. In some cases, simply resetting the furnace may fix the problem, but if the error persists, you will need to troubleshoot further.
Resetting the furnace and troubleshooting further
One of the most common reasons for this error code is a malfunctioning pressure switch. The pressure switch is responsible for ensuring proper airflow through the furnace’s ventilation system. If it detects a problem with the system, such as a blockage or lack of airflow, it will prevent the furnace from starting. Check the switch and its connections for any damage or loose connections.

Another common issue that triggers code 5 is a clogged or blocked exhaust flue. When the flue is clogged, it prevents the furnace from venting properly, which can cause a buildup of carbon monoxide gas in your home. It is essential to ensure the flue is clear and free of any obstructions. If you suspect a clog in the flue, it is crucial to contact a professional HVAC technician to address the issue.

Finally, a problem with the control module unit can also trigger code 5. In some cases, the CMU may be experiencing a software issue, or there may be a problem with its connections. Check the unit and its connections for any visible signs of damage, and consider consulting with a professional to troubleshoot the problem.
