The customer reported that their outdoor condenser was freezing up. I began the diagnostic process and inspected all line-set connections, finding no signs of moisture or leakage. The condenser was covered with several inches of ice and was not entering defrost mode. We will need to return once the ice has melted to complete the diagnostic and determine the cause of the issue. As this visit occurred the day after Thanksgiving, Fujitsu technical support was unavailable. We are scheduled to return next Friday to continue the diagnosis and complete the necessary work.
