Climate Master 27seer tranqulity geo thermal unit not cooling

Somethings not quite right with my unit that is about 8 years old. Its blowing air but its just not cold. Ive determined the pumps arent running as there is no vibration on them. If I pull the breakers and "reboot" the unit - when it kicks on everything is good and it blows cold air (65 at the register) - it quits after about an hour or so. The first time I did this a week ago it worked that long, the past couple days it'll only run for an hour with cool air. When I notice its not cold air I notice the pumps arent running and neither is the compressor. After a reboot I can hear and feel the compressor kick on and things are good, until they arent.
Any way to pull diagnostic codes or something to see if I need a new compressor or something?

My forum partner is familiar with geo systems. I am not. I know how they operate but not their individual problems.

You have a sophisticated system that requires circulating water system maintenance. I would hope you have an experienced service company that maintains your system.

I can help you but I need a model number of your systems air handler.

That unit will go into a hard lockout if the internal condensate overflow detects a backed up drain.
It sounds like you need to clear the drain.

A good test is to pour water into the primary drain pan. It is the top panel on vertical models.

You can pull up trouble codes by jumping the 2 TEST terminals on the control board.
Count the flashes.
1- no fault
2-high pressure lockout
3-low pressure
4- freeze protecting sensor 1 lockout
5- freeze protector 2 lockout
6- drain lockout
7 - over/under voltage
9- swapped thermister

Reset power to exit.

It is hard to see the test pins. I have trouble and I know that they are there.
