My GE PTS25LHRARCC's freezer wont seem to stay at 0. All of a sudden my freezer was creeping up in temp, eventually getting to 36-38. I did some trouble shooting and thought I had it nailed down to the Defrost Thermostat, unfortunatly that didnt work. I took off the metal panel in the back top of the fridge and started pressing connections to make sure they where all tight. They where, but as soon as i touched one the compressor kicked on and then brought the temp back down. I thought it was just a loose connection, but the compressor keeps on not coming on, untill I press the connections.

Now its to the point where I can press the plug and I can hear the compressor come on for about 30 seconds, then it kicks off again. Any advice would help, Thanks
