It should be around 35 degrees F , I am storing food in it. The refrigeration is r22.The thermometer is a dial. A third tech looked at it today, and said that it needed more refrigerant. It seems to be doing fine. there was some ice on the coils, but the compressor went off and the ice went away. But if all it needed was more refrigerant, then why did the other two techs not recognize that? I am leaving for mexico in the morning, and I hope the problem is solved.
