What is wrong when my thermostat is turned off but the air conditioning unit fan outside is still spinning and keeps spinning all day?

If the spinning is slow, I might suggest the wind as a possible answer but I'm not sure.

Will power surge through an air conditioning unit if the unit is turned off at thermostat?
This question is a little vague, but I'll make by best attempt. I am assuming you mean a whole-house HVAC unit, and that you are concerned with a possible power surge so you want to shut the unit off at the thermostat. If this is correct, you need to know that the thermostat doesn't control the HVAC unit the way a switch controls a light fixture. As long as your HVAC breaker is on, you will have AC power at the HVAC unit. This usually includes at least a condenser unit outside and a blower either outside or inside. All the thermostat does is tell the HVAC components when to use the power applied and when to do nothing. The power does not flow through the thermostat to the HVAC like power through a switch to a light. Think of it this way: 'Off' on the thermostat doesn't mean power off. It means 'power available, but unit not running'. So, if you want to protect your HVAC from the potential of a power surge you will have to shut off the circuit breaker(s) feeding the HVAC components, not the thermostat.
What could be the cause if the central air conditioning came back on but was not cooling after there was an electrical power outage in our neighborhoood for about 15 minutes?
It is possible that the power surge/outage damaged the capacitor of the air conditioning unit. If when the A/C is turned on, and the fan on the outdoor unit (usually located at the top of the case) is not turning, or is turning very slowly and/or sporadically, it's the capacitor.
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 is air pressure inside a home greater than outside air pressure on a cool day?
If the building is not air tight the presure should be just about the same inside or outside. If all the doors and windows are shut and you turned on the heat, the presure may be slightly higher inside.

What is wrong if I turned the air conditioning off but the fan is still blowing?
It could be that the fan switch on the thermostat is turned on so the fan runs all the time not just when the A/C or heat is on. This is supposed to be the most efficient method.

The extra load imposed by the air conditioning compressor is overheating the engine. This could be caused by numerous things, but the most common would be either a broken thermostat, low coolant, or a badly tuned engine. Take it to a mechanic.
