## What is Danfoss Troubleshooter?

Download Ref Tools to access the latest version of Troubleshooter. 

Troubleshooter helps you diagnose and resolve many issues that pop up in HVACR systems. Through a streamlined and easy-to-navigate interface, you can check on specific parts of a system and search through the most common symptoms. Once you’ve identified the problem, Troubleshooter recommends possible solutions for you to try. 

Troubleshooter is a valuable, time-saving app for installers and service technicians, enabling you to quickly resolve service calls and move on to the next one.

You can also download Troubleshooter’s database, so you can use it with or without an internet connection—which is great for remote service destinations.

How to use Troubleshooter
When you start up Troubleshooter, you’ll see a refrigeration system divided into four main areas: low pressure, high pressure, compressor, and liquid line components. Select one of the four areas and you will be able to search through potential symptoms for that area in the system. Once you identify the correct symptom, Troubleshooter will show you the possible causes for that symptom and the steps required to correct it. It’s easy to move back and forth between the symptom/cause and the solution pages.
