Performed diagnostic on the main system. I found the outdoor fan motor had failed. This was causing the compressor to shutoff on thermal lockout. I also found the outdoor starter was pitted at the contacts. I spoke with Mr. Driscoll and he chose to have the motor and starter replaced. I replaced both components and cycled power at the thermostat. I also washed both outdoor coils and secured the compressor wiring on both systems. Both systems are operational at this time.
