Contactor
Our ac unit will not come on so I checked fuses no problems there, changed contractor and hit the reset and the unit comes on but as soon as I release the button it shuts off, I don't know what to check next any suggestions?

Welcome to the forums! It is a "contactor", not a "contractor", which may be confusing some. Have you had the refrigerant checked by an HVAC person, yet?

You hit what reset..... a little pushbutton on a pressure sensor or you pushed in the contactor ?

Ok... that isn't a reset. You manually activated the contactor by pushing it in mechanically instead of electrically.
At this point you will need a voltmeter to determine where you are losing the voltage that should activate that contactor. One thing you can do is to check for a float switch somewhere in the white drain line near the air handler. You would see maybe two small wires connected to it.
Otherwise.... the contactor won't pull in by itself if the system is low on refrigerant.
