Answer Luis
??????? That is very odd. It sounds as though your control head is going bad. It seems to have a loose connection internally or on the plug coming out. That loose connection is shorting over to another wire and shutting off the compressor or fan when it shouldn't be. My recommendation is to take it to a reputable service shop or even, dare I say it. the dealer *shiver* to have them troubleshoot it. I am sorry but I can't do too much over this site to help you out with this type of problem. But my guess is that they will replace your control head, and you will be working fine shortly after.
Thanks for your question and good luck.
