Lg Window Unit Compressor Runs The Entire Time The Unit Is Turned On. Turning Thermostat All The Way Up Does Not Even Shut It Off. Air Is Plenty Cool. What Could Be The Problem?

Could be a number of things.
First I would check that the RY-COMP contacts are not welded together.

Here is a manual which should help
LG LWHD8000R 8,000 BTU Window Room Air Conditioner Service Manual - ApplianceDigest.com

You have to join the site to download the manual but it is free and this is a very good site for manuals and other info for the appliance repair DIYer.

RY COMP connections are not welded together and connections are tight. Manuel says to then check the RY COMP itself. How do I do that?

I am not sure what they mean.
You have checked it since the contacts are not welded together the control board is energizing it all the time so the problem is further back in the unit.
