I went on you tube to try and figure out what might be causing this problem. It seemed that the problem was either the temperature thermostat or the defrost timer. I figured that seeing as I had never ever seen any frost in the freezer that the problem probably wasn't the defrost timer. So I ordered the temperature control thermostat, received it the very next day and in ten minutes removed the old one and installed the new one and we were good to go. It's been working just fine for the last week.
