Why does LCD display on the thermostat AC in the house periodically shuts off happens more during the summer then after a few hours it turns back on and the AC kicks in?

Generally speaking, a thermostat should command an air conditioner (or a furnace) to turn off once the thermometer inside the thermostat senses that the a given temperature has been reached. For example, if you have manually set your thermostat at 75 degrees, the thermostat's job from that point on is to maintain that temperature, or a temperature within one or two degrees of that. If the thermostat didn't turn the air conditioner off periodically the house would get much cooler than desired; using up a large amount of (expensive) electricity, and over burdening the air conditioner compressor, prematurely wearing it out leading to a costly repair bill. You might look at as the thermostat giving the air conditioner a rest and your wallet a break. Many, if not most thermostats also serve another role which is to safeguard the electronic startup up equipment and motor of the air conditioning unit. You might experience this when attempting to turn the air conditioner back on within a few minutes of it having turned off. This is a built in safeguard feature which protects certain delicate components inside your air conditioner from premature burnout or an electrical overload. If you experience this it's best to wait ten minutes or so for the safety system to reset. Hope this answer was helpful. ---------------------------------------------------------------------------- Thanks for the reply, but when I said it "Shuts Off" it means that the Thermostat LED goes blank, as if there is no power to the syste.


Why does the temperature gauge go in the hot range only in the hottest part of summertime when the air conditioner is on The check gauge light goes off when the air conditioner is turned off?

The air conditioner will create extra heat. So if it's really hot to begin with turning on the AC will only make it harder on your cars cooling system. If you haven't had your coolant flushed/thermostat changed in a long time you might want to try that. Also make sure there are no obstructions in front of the radiator.
