Our Dometic AC and Single Zone LCD thermostat is set for the temperature we want. The unit will run until the inside temperature gets down to the set point. Once it gets to that point the AC does not come back on. The inside temperature can go 10 or more degrees above the set point. If we turn the thermostat off and back on, the AC will run another cycle and then not come back on again. We tried settings the fan to low instead of auto and it still shut off when it reached set point. Why doesn't it continue to cycle?
