Is your RV rooftop air conditioner not blowing cold air?

At the risk of being obnoxiously obvious, that’s not a good sign. Unlike your residential or automotive air conditioner, an RV air conditioner cannot be recharged. So you can’t just pump another can of Freon into the tubes and cross your fingers. No, it’s time to put on your thinking cap.

I’m going to ask you to grab a flashlight. Beyond that, all you need is a screwdriver to pull off some access panels and shrouds. I’m not going to ask you to whip out a multimeter or dust off a technical manual – this isn’t that kind of instructable.
