A/C runs on high

[Johnontheroad]

We're currently near Houston, parked in the sun, it is 72F outside. AC is running fine. But recently I've notice the the front AC frequently will switch to a high fan speed. The others don't. It seems to me that the AC is switching to high much, much faster than it ever did before.


Seems to me that it used to switch to high only at much higher outdoor temps. Is this something I should keep an eye on or take some kind of action?

Mine does the same thing. I suspect it's because the thermistor / temp sensor for the front of the coach thinks it's warmer than it really is. Mine is located on the passenger side and typically senses warmer than the others. People have loosened the screws for it to pull it further from the wall; I'm still experimenting with it.
