What to Do When You Get an Error Code on Your Trane Furnace

When you have a Trane furnace, you’ll get error codes whenever something isn’t working correctly. If you see an error code on your Trane furnace, it means there is a problem somewhere. Understanding what that error code means and how to troubleshoot it can save you lots of time and money. Trane furnaces use a code system to help repair technicians figure out what is wrong with the furnace if something goes wrong with the unit. The diagnostic codes are displayed as numbers or symbols on an LED readout panel or as words in a message log. This blog post covers common Trane error codes, what they mean, and how to troubleshoot them so your Trane furnace will work smoothly again.

To avoid this, you should replace the transformer in your furnace as soon as you see the error code 16.

To avoid this, you need to replace the flame sensor as soon as you see the error code 22.

To troubleshoot this error code, you should clean or replace the low limit switch.

Error Code 25

To avoid this, you need to replace the flame sensor as soon as you see the error code 25.
