My trane xe1000 runs inside but doesn't blow cold air and the fan outside doesn't turn on. I've read some threads on this topic and the common fix I've seen is to replace the capacitor. I removed the cover to the machine and I'm not sure if the white cylinder on the bottom is the capacitor or not since it only has two connectors at the top instead of the three that I've typically seen. It also doesn't look like its bulging. Am I heading in the right direction by replacing the capacitor or could it be something else. Thanks
