    our geothermal pump will start up run fir maybe 5min and then quit. The fan keeps running. We have tried restarting the system several times by throwing the breaker. Have also added water and antifreeze to the system and have checked for leaks in the house. Nothing. Any ideas

    Yes, contact a pro. Is there a low pressure light anywhere? High pressure? Entering water temperature, leaving etc? Can't tell you much without data, and that's why you should call someone. There are too many variables. Geo is not simple unfortunately. Most HVAC guys are clueless but they can at least check pressures for you if nothing else.

    Just to make sure that (refrigerant) pressures are one of the last things to check. Start with flow and temperatures. More info is needed. What kind of system, when installed, as much info as you can provide.
    Sorry, but the "it shuts off after 5 min, and then does not run anymore" could be many things.
    Please help us to help you....
