    Econar geo source 2000

    Hi I'm been working on a econar geo source 2000 and I think I'm having issues with the expansion valve. The expansion valve is one I haven't ever seen before. Can someone explain how it operates it looks like it has 24v going to it .
    Thanks

    If it has power going to it then it’s probably a electronic expansion valve. A controller opens and closes it using data from temperature and pressure sensors in the system. What know me of problems are you experiencing?
