Air Conditioner settings

My rig has front and rear ducted a/c's. The control panel is in the bedroom and has the following settings. high and low fan, high and low cool, automatic and heat and off. When I set the front or rear unit to automatic or low/high cool the compressors cycle off and on, but the fan never quits blowing. Sometime during the night it will shut off sometimes, but usually comes right back on blowing room temperature air. Is there something wrong with my control panel, temp sensors or am I setting the unit incorrectly..

    I run a bit warmer, but same concept.

    To the O/P.

    I often read posts from folks annoyed by the "noise" of the A/C. the solution is to leave it on HIGH and let your mind filter out the blower noise.. This will "mask" some of the compressor noise, and also the kids playing outside, or the "Big children" (Adults by another name) Fighting on the site next door,, or the police hauling them away in bracelets, or... Well perhaps not that last one.

    (Ok, so it was not the site next door, it was about 10 down)

    Your sensors may be fine. The problem is often their location. In our coach the rear sensor is under the cabinet over the bed. If the sum is on that side I may have to set the stat at 90 degrees to get a 77 temp in the BR. Even lights in the vicinity will heat up the sensor making the stat think it is warmer than it really is. Also unless the stat is set on Auto cool the fan will run continuously in all other modes


    Thanks, going to take the sensors apart tomorrow and see if they are dirty or ? The fans on my a/c's run all the time, even set on auto cool. But as I said earlier, some times late at night when the outside temps drop, they shut off. Makes no sense to me, I have never had a/c's that run all the time...

    Check the location of your sensors. My front sensor is located on the wall just under my rear AC, so we have to lower the rear AC temp about 4 deg to get even cooling. My rear sensor is under the rear TV, so again we have to watch the front and rear AC set points to ensure even cooling.

    We found out that our 2 AC's must be on the same mode. If you have the front on auto the back needs to be on the same. We leave our fans on low and they even if the compressor isn't. We leave both AC's on Cool with the fans on low. Leaving the fans on when the compressor isn't running will prevent the musty smell from condensation. We have proven that to be true.

    Checked the settings to make sure I had it correct. It says auto cool. The only way it shuts off is to turn the thermostat up until it quits and then it will come back on and run continuous until I turn it up. I am thinking my sensors might be bad..Anyone know how to check them...

    Don't know what thermostat you have but when my thermostat is set to "AUTO" the A/C only runs when it turns on to cool. When on the "ON" position the fan runs all the time.
