I should mention that turning the temperature dial had always acted differently than any other AC I've seen. With most, the further to the red the dial is turned, the less cool the air would get. On this AC the air was either very cold or room temperature--no in between. When the cold air quit I checked all the dashboard gauges. All looked normal.
We're on day one of a two week Florida vacation. Not looking forward to checking into a hotel while the RV sits in the shop. Any ideas would be appreciated.

In car A/C's the hot to cold temperature switch is actually a thermostat that turns the compressor on and off when the inside temperature matches the dial. In Thor RV's (at least Axis/Vegas) that dial is attached to a flap that is supposed to mix the cold air from the A/C with outside air. Theoretically you should be able to regulate the temperature of the air coming thru the vents by setting the dial so that the mix of A/C and outside air is the temperature you want. However in both my Vegas and Axis it never worked that way. As you indicated, it is always either all off or all on. But unlike a car in the Axis/Vegas, the compressor never turns off.
