Replacing 2008 Geocomfort GT060 (5 ton)
Forgive my poor terminology. Very new to geothermal.
Cooling quit working a week ago. Since then, 3 techs have been out and replaced 3 electrical parts, none of them addressing the root cause. As of today, they think the issue is the whatever little black piece triggers the compressor to enter “second stage.” It was tripping a fuse and literally burnt up the brand new board they were installing. At this point, I think I’m just going to replace the entire thing given it’s age.
However, my concern is whether there could be something in the underground heat loop that caused issues with the interior system. My only reason for concern is that I had a patio installed over part of the exterior system (probably stupid, I know). However, that was installed a year ago and I’ve had no issues until now. it just bothers me that their description of the root cause isn’t very clear to me.
Again, I don’t mind replacing the system. Just want to make sure I’m not going to have the same issue again if something in the loop is messed up. I’m assuming they have a way to test the loop separately to make sure that’s not a factor?
Thanks for any insight. I’ll ask them more tomorrow when they come to quote a replacement.
