Dometic AC in auto mode

We had one like that in our last rig. Think what its doing is checking the air for temp. It the temp is not to high it does not start the compressor and it may start and check air temp several times and not turn on the compressor. We now have a built in AC in one of the bedrooms in our home that does the same. I decided if you check the time between fan runs it may be on a timer so its just checking air temp. Its trying to save the power from running the fan full time. Not sure there is a cure and it is the smart way to go, I guess. But I just gave up and run the fan full time. The starting and stoping of the fan bothers me more than running it full time. I also question the amount of extra power it takes to start the motor several times over just letting it run..
