With this app you can have a better understanding of the diagnostic codes shown in the display of the indoor unit.

First choose your model, and then choose the code from the list.

The app will guide you with an explanation for the code, and a recommendation to fix it.

Additionally, you could also type the code directly with our advanced search.

This app is ONLY for the units sold directly in the US. (will not work for units sold in Mexico)

Remember to always call your certified technician prior to open your equipment
