Upon arrival technician found that the 15 MFD capacitor had failed. The technician replaced 15 FD capacitor. Technician also noticed that when the system froze up and defrosted, the system flooded itself. When the installers install the equipment originally they moved the circuit board down to the bottom. And when the unit flooded it corroded a little bit of the circuitboard. But the system is working properly at this time.
