Uppon my arrival found the dual capacitor has failed on the compressor side. It was not allowing the compressor to start up. I replaced the capacitor with a warranty capacitor 40/5 mfd. Performed start up procedures and cleared the drain line with CV oil cleaner and water. I ran the unit for about 20 minutes to make sure it was all working properly. I loaded my pictures to service titan and left the system in proper working condition. I would recommend installing a surge protector on this unit to help protect the control board and electrical components.
