How to fix it by myself ...We set the thermostat at 75 degrees.I am mechanically inclined.

There are a couple of reasons for this "short-cycling" effect. The first thing I would ask is, is this a new problem, or is this an ongoing problem and how the system normally operates?
If it is a new problem, there is definately a mechanical failure, and the thermostat is the likely culprit (although not the only possibility). Be sure to match your new thermostat to the type of equipment you have (i.e. heat pump, electric heat or gas, single-stage or two-stage heat).The instructions for installation are included with the new thermostat and easy enough to follow. (Make sure the power is off to the system)
Before you do all that, let's rule out the obvious. Is the thermostat sitting in the path of an air vent that would cause it to resolve the temperature too quickly? If so, redirecting the air flow or relocating the thermostat is your answer.
Good luck and God bless you!

Luckily, it's most likely the thermostat's problem. It operates on a principle called "hysteresis", which means that it will keep the AC on til it's a bit beyond the coldness level you set it at, so that the AC can stay off for awhile, and then it will pop on once it hits the threshold again.
Unfortunately, thermostats for AC's are generally digital. Basically, your thermostat is supposed to allow the room to cool down to a bit below the temperature you set it for, so that it takes longer for the area to heat back up.
Pop it open and see if you can find any wire coils. These are generally used for low tech thermostats, and there's a magnet that performs the hysteresis effect.

I think you have your a/c and spouse confused....
New thermostat control unit should be checked. Locate it and place a match near but not on it and see if it stays on longer. Also, check for leaks in house that may let air temp change rapidly. Had same problem with heater this past winter and used felt strips around door to stabelize.

Sounds like a compressor motor problem or a resetable fuse?(thermal type usually) Check the blower motor too same type of problem possible.)
check the interval on the thermostat too. Is the room at 75 degrees ?

first try setting it at a lower temperature.
take the cover off and watch the mercury switch
is the thermostat getting blown on by the cold air?
(move it)
is it running off a power strip that has a weak breaker?
(plug it into its own circuit with no cheap power strip to shut off on you)

This sounds like the indoor thermostat/temprature unit going bad. I have never replaced one of these but I have been told it is a simple wire-to-wire screw on the wall job.

It should reach the temp 75deg to turn off. If it turns off before reaching 75deg you need to replace the thermostat. I had the same problem.
