Read some of the reviews and looked at the parts ordered by others. I knew that's what the problem was before reviewing the comments. Installed the thermostat and timer. So far the unit is cooling down. Let me add this. The person who helped me named Gay was very helpful. After installing the parts and waiting a day to allow the sealer to dry on the wire connectors, I started the unit and nothing happened. So I reinstalled the old timer and the unit started right up. So nothing I did with the Thermostat was wrong. Make a longer story short, when Installing the NEW timer, don't freak out because it doesn't work. The NEW time starts in the defrost mode for 30 mins before it allow the compressor to start. Thank you tech support (named Gay). Thank you. Other tool, wire strippers/crimper.
