Looking for some help with my GeoComfort GS series. I bought the house 3 years ago with the geothermal already installed so I am still getting familiar with it but it has been trouble-free until this point. I currently have a "Water Flow" fault from the unit control board and the Comfort Alert is showing a "Short Cycle" error. The compressor is not running when these codes are up and my fan is running on low. If I power cycle the unit, the compressor will kick on and run for about 2 minutes and then kick off. The fan will remain running. Every once in a while, the compressor will turn on again and run for 2 minutes and then shut off again. My thermostat is a Gen. 3 Nest that I've had for about a year and haven't had any issues with, yet. I am leaning towards a bad control board or a bad freeze protection thermistor. I still need to verify control voltage out from the board to the compressor. I guess if it's there in these situations then the compressor is bad? Any help/insight would be greatly appreciated.
