If it goes bad - temperature in the coil will be close to cab temperature on the diagnostics software.
The aluminum tube inside the cab that is supposed to be ice cold (under the bunk) would be extremely hot when you touch it.
Also you can see Condenser Fan check mark (System Monitoting tab) active, but Condenser fan is not spinning.
Another way to check it is unplug it and see if 12V are coming to it but it's not activating (after you plug it back).
