    I live in Lewes, Delaware
    I have a 4 ton Climatemaster Geothermal
    Open loop system
    1hp variable speed well pump
    Franklin Electric Subdrive 75 constant pressure system
    York air handler
    Geo is in crawlspace, directly under master bedroom.

    I've noticed that when my geo runs and then cycles off, after being off for a few mins, there is a low motor hum, for split seconds at a time. It will come on for a split second, go off. It will do this every min or so until the geo cycles on again. Is this a cooling circulating motor? Or do I have something else going wrong. I have never noticed this hum before. My system is going on 6 years old

    Hi and welcome!

    Without being there, I will still hazard a guess that the noise you are hearing is the cooling fan in the variable speed control box, or the box itself as it ramping around the pressure setting due to a pressure leak somewhere else in the system. Good on you for taking notice of the change. Time to get a well service tech out to take a look.

    Is there a motorized valve that could be humming?

    I don't know the internal components of the climatemaster geo, but there is a geothermal valve that's motorized, that opens and closes when the geo calls for water.

    I'm sure it's not the constant pressure fan. That's a higher pitch fan noise.

    This noise is a quiet pump/ valve opening and closing.
    Good possibility that it's the geo valve.

    I think it might be some installation issues. I never heard about this before.
