We have a 2015 coachman Liberty express travel trailer, when I have a/c on it never turns off even when I turn thermostat all the way up, I have to manually turn it off, is this the normal way they work?? We just had the a/c unit replaced . It does turn off when I manually turn the whole unit off. Any ideas greatly appreciated! Thanks.
Is the AC running all the time or the fans? In my unit I had to change the control to FAN then change setting to auto, then move back to AC or Heat. If you don't do that the fan runs all the time when AC or Heat are on.
